October 2015 ABSTRACT Knowledge of the materials has always been necessary for those who design. With today’s stringent demand on quality regarding manufacture, materials and execution, it is often assumed that purchasers, architects and contractors posses the necessary knowledge of that with which they work. This paper described one of the commonly used engineering materials nowadays. Epoxy resin which is routinely used as adhesives, coating encapsulates, casting materials, potting compounds and binders. INTRODUCTION Epoxy resins were first commercialized in 1946 and are widely used in industry as protective coatings and for structural applications, such as laminates and composites, tooling, molding, casting, bonding and adhesives, and others. The ability of the epoxy ring to react with a variety of substrates gives the epoxy resins versatility. Treatment with curing agents gives insoluble and intractable thermoset polymers. Some of the characteristics of epoxy resins are high chemical and corrosion resistance, good mechanical and thermal properties, outstanding adhesion to various substrates, low shrinkage upon cure, good electrical insulating properties, and the ability to be processed under a variety of conditions. Depending on the specific needs for certain physical and mechanical properties, combinations of choices of epoxy resin and curing agents can usually be formulated to meet the market demands. HISTORY Epoxy plastic has its roots far back in history, to be specific, in 1936, when Dr. Pierre Castan in Switzerland succeeds in…...

Fusion Bonded Epoxy Coating

...Fusion Bonded Epoxy Coating Engineers and Researchers have found that fusion bonded epoxy coating is the practical and scientific way for protecting steel reinforcement against corrosion Applying an epoxy coating to steel rebar prevents the chlorides from reaching the steel surface. And since the material is applied to the rebar at a mill away from the job site, it is not weather dependent and will not cause construction delays Cracks in the concrete, allowing penetration of chloride bearing waters, is not a factor because the protection is applied on the bar surface where the problem is usually observed. The most effective form of epoxy coating is the fusion bonded method. This allows the coating to achieve adhesion as the result of the heat-catalyzed reaction. An epoxy coating is formed by combining an epoxy resin with the appropriate curing agents, filters, pigments, catalyst and leveling and flow control agents to achieve the desired characteristics It is applied from an electrostatic charged powder state to a pre-heated rebar. The powder when comes in contact with the hot bar, it melts, gets and cures to a well adhered, continuous corrosion resistant coating. The first fusion bonded epoxy coating designed specifically for reinforcing steel was put in the market in 1976. Since then, continuous research, design and testing have taken place which have enhanced and confirmed the effectiveness of fusion bonded epoxy coated rebar [FBECR] in preventing steel......

...took a piece of 12-inch PVC left over from another project and decided to use that for the box shape. This enclosure is made from 6061 aluminum, carbon fiber, and a little epoxy to hold it all together. Since I knew the radius of the PVC, the outer size was easy to figure out. I then drew up a few braces using a square, adjustable angle finder, and some Mobile Solutions templates. Once the final MDF brace template is done it can be transferred to aluminum on the router table. I'm lucky enough to work with someone who could transfer my design and CNC it, so they were all perfectly symmetrical. For the face of the enclosure I used 1/4-inch 6061 and cut it on the table saw. I cut an angle on each side, as close as possible to the angle the carbon meets it. Two holes were rough-cut with a jigsaw for our Polk Audio MM1040 woofer. I then used an MDF template to cut perfect holes on the router table. A small landing arch (slightly smaller in diameter than the end cap) was glued to the end cap. This provides a spot for the carbon fiber to be glued to the aluminum. Squares and clamps were used to ensure the end caps were straight. More clamps and pieces of MDF were used to attach the braces. A 1/2-inch square aluminum rod was glued to the back of the face for a spot to glue the carbon fiber. Duramix panel bonding epoxy was used for all aluminum/aluminum attachments. Nineteen-ounce dry carbon fiber weave was taped to the PVC then wet-out with surfboard resin. A second and a third......

(5 points) Plot the longitudinal tensile strength of an E-glass/epoxy unidirectionallyreinforced composite, as a function of the volume fraction of fiber, assuming tensile strength follows a volume rule of additivity. Use the properties from attached Tables. 4. (5 points) What is the maximum volume fraction of spherical fillers that could be obtained in the particle-reinforced composite assuming cubic packing? Please show the step. 5. (4 points) Using the Takayanagi model and assuming uniform strain in the matrix, derive a relationship for the transverse, tensile compliance of a unidirectionally-reinforced composite. 6. (6 points) Two test specimens have the same Young’s modulus in tension. However, one of the specimens is homogeneous while the other one has two layers with one layer stiffer than other layer. How will the flexural modulus of the two specimens differ? Explain. (Hint, use Parallel and Series model to calculate the modulus to compare them. Assume the modulus of stiff material is 1X109MPa as and the modulus of soft material is 1X108 , and the volume fraction of each one is 0.5) Properties will be used for solving above problems: The modulus of S-glass is 85.5 GPa, the modulus of E-glass is 72.4 GPa, the modulus of Epoxy is 3.5 GPa and the modulus of polyamide (nylon) is 3.0 GPa. The tensile break strength of E-glass is 2.4 GPa and that of epoxy is 45 MPa. The break strain for E-glass and epoxy is 2.6% and 1.28%, respectively. ...

...phenyl group, around 1600-1400 cm-1 (Figure 6 and Scheme 2). The Rf value of 0.72 confirmed that the extracted was indeed epoxide 8, with a 10% error from the literature value of 0.80.4 The NMR of 9 displays two peaks in the aromatic region, 6.5-8ppm, representing the 6 hydrogens in the phenyl group. The major difference between the NMR of diol 9 and the NMR of epoxide 8 is the peaks appearing in the 5-3 ppm. This is due to the change occurring during HKR. The hydrogens of an epoxide are in a permanent confromation and therefore Hf and He, in Figure 2, are coupled separately to Hg. However in the NMR of diol 9, the same coupling of HF and HE to HI is observed (Figure 1). Figure 2. Expanded NMR of (s)-1,2-Epoxy-3-phenoxypropane 8 The Jacobsen’s Salen (Co) Catalyst successfully yielded enantiomerically pure diol 9 and epoxide 8. The HPLC spectrum reveals that the remaining 8 contained 99.4% ee and the remaining 9 contained 93.8% ee. Although the results of specific rotation remained inconclusive, HPLC results are considered a more accurate chiral categorization tool. The Jacobsen’s Catalyst synthesized by initially reacting amine 1 with L-(+)-tartaric acid yielded an (R,R) chiral resolution of the Jacobsen’s Salen(Co) Catalyst 6. When amine 1 is initially reacted with the D-(-)-tartaric acid the final product of the synthesis is an (S,S) chiral resolution of the Jacobsen’s Salen (Co) Catalyst. According to Eric Jacobsen, the each......

...PST 522E – Synthesis and Characterization of Macromolecules CHAPTER 4 DYNAMIC MECHANICAL ANALYSIS OF EPOXY-CARBON FIBER COMPOSITES 1. THEORETICAL PART Composite materials have been used widely for daily life applications for many years. Polymer composite systems have a large scale for industry or research area due to their light weight, design flexibility, and processability [1,2]. Using polymer composite is widespread to use for special engineering materials such as aerospace industry, automotive and civil engineering structures because of their outstanding mechanical properties. Polymer composite theories were established on properties of composite constituents, volume fraction, shape, matrix-inclusion interface [3,4,1,2]. Mechanical properties of polymer composites are significant when they use for a building or an instrument which has critical points about temperature and strength properties [5-7]. Composite materials properties have been developed such as chemical, physical and mechanical, so their application area comes much bigger. Because of improvements on composites materials, their industry are growing on automotive, aerospace, electronics and biotechnology [8,9]. The important point of using nanocomposites is large scale, low cost, easy applicable [10]. In composites, two materials are mixed to make improvement in the mechanical properties. Matrix material is dominant and including material. The second material is particle, filler or fiber. Composites are......

The Use of Composite Materials in Aerospace, Wind Power and Automotive Technologies

...– able to resist neutral chemicals very well. The properties are all dependent on the structure, arrangement and geometry of the fibres, and since there is such a large variety of fibres, it is not possible to make a generic statement about the properties, although of course, for most industrial applications, the fibres have to high tensile strength and a composite modulus (see section 1.3). 1.3 Matrices Matrices tend to be thermosetting isotropic materials that allow load transfer between fibres [1]. The matrix acts as a protective layer for the fibres so that they are not so easily scratched, damaged or oxidised and affect the overall properties of the composite, or cause malfunction. Even though the most common thermoset resins are epoxy, vinylester and unsaturated polyester among others, a relatively new but growing area is in metal matrix composites (MMC’s), which comprises of a continuous metallic phase as the matrix, with other phases artificially introduced into it [5]. The most advantageous reason for the interest in MMC’s is due to their capability to resist thermal distortion. Another type is the ceramic matrix and when used as ceramic matrix composites (CMC’s) then there are four main classes: glass, conventional, cement or concrete and carbon/carbon [5]. The main advantage to CMC’s is their relative ease of process. The properties of an overall composite material depend on the relative quantity of fibres and matrix [1]. One property is the composite modulus, Ek...

Oven cured Epoxy application and connector assembly 3. Oven cured epoxy polishing General Guidelines The following contains information on the placement of fiber optic cables in various indoor and outdoor environments. In general, fiber optic cable can be installed with many of the same techniques used with conventional copper cables. Basic guidelines that can be applied to any type of cable installation are as follows:     Conduct a thorough site survey prior to cable placement.     Develop a cable pulling plan.     Follow proper procedures.     Do not exceed cable minimum bend radius.     Do not exceed cable maximum recommended load.     Document the installation. Conduct a Site Survey The purpose of a site survey is to recognize circumstances or locations in need of special attention. For example, physical hazards such as high temperatures or operating machinery should be noted and the cable route planned accordingly. If the fiber optic cable has metallic components, it should be kept clear of power cables. Additionally, building code regulations, like the National Electric Code (NEC)** must be considered. If there are questions regarding local building codes or regulations, they should be addressed to the authority having jurisdiction, such as the fire marshal or city building inspector.

...1. Who is the genesis of the e-Epoxy project? While Epoxy can be viewed as a company that is constantly looking to explore and is open to new ideas, the credit for the successful launch of the e-Epoxy project should be given to Ian Telford. Ian took advantage of the training and tools provided to him and showed the initiative to work on a new venture for his organization. 2. If you were a member of the e-Epoxy leadership team, would you support Ian? Yes. Ian displayed confidence and ensured that he was always well-informed about the market. As a team member, I would feel extremely comfortable working with a knowledgeable leader who could motivate the team and always look out for the team members no matter what the outcome may be. The case also describes the positive responses towards Ian’s attitude in making the e-Epoxy project a success and places particular importance on his ability to lobby for the ideas he believed in as well as building a good support team. Ian ensured that he knew how to take tough decisions and displayed incredible leadership skills. 3. What are the differences in the process of developing an opportunity within a corporate environment as opposed to independently? In my opinion, developing business ideas within an organization have more pros than developing an idea independently. While it is quite difficult to take radical decisions when working within a structured organization, it is a relatively safer environment if you have the sources and...

...Unit 8. Lab 1. Fiber Optic Connector Assembly Fiber Stripping “The outer sheath of fiber cables can be removed using electrical cable stripping tools, and scissors or a razor blade can trim the Kevlar strength member. However, the fiber coating must be very carefully removed to avoid damaging the fiber, surface flaws and scratches are the cause of most fiber failures. The coating can be removed using fiber strippers.” (Newport, nd) Fiber Termination “End-face surface quality is one of the most important factors affecting fiber connector and splice losses. Quality end-faces can be obtained by polishing or by cleaving. Polishing is employed in connector terminations when the fiber is secured in a ferrule by epoxy.” (Newport, nd) Fiber Cleaving “Fiber Cleaving is the fastest way to achieve a mirror-flat fiber end and it takes only seconds. The basic principle involves placing the fiber under tension, scribing with a diamond or carbide blade perpendicular to the axis, and then pulling the fiber apart to produce a clean break.” (Newport, nd) “Once the optical fiber is terminated with a particular connector, the connector end-face preparation will determine what the connector return loss, also known as back reflection, will be. The back reflection is the ratio between the light propagating through the connector in the forward direction and the light reflected back into the light source by the connector surface.” (Newport, nd) “Minimizing back reflection is of great......

...to the CNT. Potential topics of oncoming focus are highlighted. 2003 Elsevier Ltd. All rights reserved. 1. Introduction Since the documented discovery of carbon nanotubes (CNTs) in 1991 by Iijima [1] and the realization of their unique physical properties, including mechanical, ther-mal, and electrical, many investigators have endeavored to fabricate advanced CNT composite materials that exhibit one or more of these properties [2,*3,*4]. For example, as conductive filler in polymers, CNTs are quite effective compared to traditional carbon black micro-particles, primarily due to their large aspect ratios [5]. The electrical percolation threshold was recently re-ported at 0.0025 wt.% CNTs and conductivity at 2 S/m at 1.0 wt.% CNTs in epoxy matrices [6]. Similarly, CNTs possess one of the highest thermal conductivities known [*7], which suggests their use in composites for thermal management [2]. The main focus of this paper, however, will be on the use of CNTs as discontinuous reinforce-ment for polymer matrices. The CNT can be thought of as the ultimate carbon fiber with break strengths re-ported as high as 200 GPa, and elastic moduli in the 1 TPa range [8,**9]. This, coupled with approximately 500 times more surface area per gram (based on equivalent volume fraction of typical carbon fiber) and aspect ratios of around 103, has spurred a great deal of interest in using CNTs as a reinforcing phase for polymer matrices. * Corresponding author.
