Presently there are lot of materials that can be used in the fabrication of any item, so choosing a material is a major criteria. So the materials are chosen depending on the properties desired by the resulting item. The composite materials have better properties when compared with its individual components, metals and ceramics. The overall appeal of the product depends mainly on its durability, aesthetics and its final cost. Composite materials are cost effective and significantly satisfy the needs of the clients. By utilizing composite materials we can obtain high strength to weight ratio at a relatively economical cost. Moreover, they can be produced easily by basic part forming. Hybrid polymer composites have been studied of late which improves a specific property of the composite that is under question. Here a hybrid composite made of laminate of Nomex and HS glass sheets with varying percentage (1% - 2.5 %) of bisphenol dispersed in resin is prepared. The same samples were subjected to cryogenic treatment (24 hrs and 72 hrs). The results of tensile strength, flexural strength and hardness were compared for all the specimens 24 hrs cryogenic, 72hrs cryogenic and non-treated specimens. The results showed that the hardness of the cryogenic treated bisphenol based PMCs has increased with the weight percentage of Bisphenol indicating the fact that the laminates can withstand more loads at subzero temperatures The increase observed was about 3 – 4 % more in terms of BHN number. At the same time the tensile and flexural strengths have considerably reduced after treating the PMC cryogenically as the laminates becomes more brittle when treated. The tensile strength increased by about 10% approximately and the flexural strength reduced by 300%

Graphene, Nomex and High Silica Glass are predominantly used in many applications individually because of their distinct mechanical and chemical properties. Graphene, because of its ability to show a significant increase in the properties at low filler concentration, has fascinated the community working in academicand industrial fields. The main aim of this work is to study the polymer composite reinforced with graphene, Nomex and High Silica glass forits mechanical properties. The composite was fabricated using Hand layup process. Nomex and High Silica glass along with graphene nanoparticles of 1, 1.5 and 2% by weight were used as reinforcements. Mechanical tests were conducted on the fabricated laminates, according to the ASTM Standards, to test their properties. The results obtained from these tests reveal that properties such as tensile strength and hardness increase with the increase in weight percentage of graphene. It was observed that laminate with graphene concentration of 1.5% by weight returned superior flexural properties when compared to other concentrations of graphene. Further, the tested specimens were studied for its morphological appearance through SEM technique.

E-glass fibre and Bisphenol-A have a wide range of applications when it comes to fabricating composite laminates due to their superior chemical and mechanical properties. Bisphenol-A can alter insulation properties at lower filler volume. In the current endeavour, an investigation was made into the effect of Bisphenol concentration on mechanical and insulation properties. The composites have different compositions of Bisphenol in the range of 1% to 3%. Conventional hand layup process was used to fabricate the laminates and were tested as per ASTM. The experimental results show that there is only marginal increase in hardness and tensile strength with increase in weight proportions from 1% to 3% of Bisphenol powder and it can be concluded that the Bisphenol is not contributing to the significant changes in Mechanical properties. SEM analysis was carried out to study the morphological features of the tested specimens. Further, the stellar role played by the addition of Bisphenol is observed through the tests carried out for determining the insulation properties. It was observed that there was a significant increase in the insulation properties of the laminates with the increase in the weight proportions of Bisphenol and it is attributed that the laminates thus fabricated will find applications in the industries that manufacture thermal resistant materials. © IAEME Publication.

Fracture toughness, Hardness and Tensile Strength of the Aluminum alloy 7075-T6 coated with Cadmium with varying thickness of 10μ and 20μ were investigated. Electroplating Cadmium coating process gives excellent corrosion resistance, provides low coefficient of friction which increases the surface hardness of the material. It also provides a uniform and dense coating, in many cases, maintains surface finish as it was before plating. The specimens prepared in line with ASTM E-8M and E-399 standard were subjected to various tests. The results shows thatthe hardness of the EC coted specimens has increased by 10% and increases with increase in thickness, butthe thicker the EC coating, more brittle is the material. The Ultimate Tensile Strength also increased by 5% compared to the uncoated counterpart. There was a steep increase in plain strain fracture toughness with the increase in the coating thickness for the Aluminum 7075-T6 alloy in TL orientation. The crack growth was Unstable due to the strong adhesion between the EC coating and the alloy.

Glass fibre-reinforced plastics (GFRP) composite materials are extending the application horizons of designers in all branches of engineering. The present work is focused on development and determination of mechanical and dielectric properties of hybrid polymer composites of Nomex and High Silica Glass fabricated through handlay process. Five laminates each were fabricated for four different stacking orders with an average of 55% matrix contents. The polymeric composite was tested for mechanical and dielectric properties. It is found that the hardness was boosted in the laminate with the presence of more layers of High Silica glass fibers, presence of higher number of Nomex contributed for an increase in the compression strength and High Silica glass fibers and Nomex had an equal effect in increasing flexural strength of the composite. The Nomex and E-glass fibers present in the core of the composite covered by High Silica glass on the outer layer of the composite offered very good dielectric strength and surface resistivity for the composite and the absence of E-glass fibers have enhanced the dissipation factor. Further all laminates showed a greater stability towards chemical attack and temperature stability was observed up to 300° C. © 2017 Elsevier Ltd. All rights reserved.
