“…One possible reason is the compact structure that supports less exposure to oxygen [36]. Aramid fiber has an inherent ability to resist fire as the polymer plays an important role in determining performance behaviour [37]. Some fibers such as nylon drip and melts upon exposure to flame and can cause severe dangers.…”

Workplace accidents are very unpredictable. Protection against these risks and hazards is of utmost importance in every profession. Clothing has always been considered one of the integral parts of personal protective equipment. The present study aims at manufacturing and evaluating protective clothing materials used by chemical workers. It was experimental. Two important resistance characteristics; chemical and fire were assessed against international performance standards. The results highlighted the fact that the right selection of construction parameters was able to make a safe fabric against such hazards. The resultant fabric was evaluated at various washing intervals and was found to be resistant to four selected chemicals through penetration and repellency index. It was also able to resist fire by passing the standard after flame and char length tests. Very little research work has been done in Pakistan regarding the manufacturing and physical assessment of clothing materials used by chemical workers. This study aimed to approach the target area where the protection and safety of the worker should be a priority.

“…Addition of Nomex T410 and High silica glass fiber increased the flexural strength [20]. These laminates have proven to be more chemical stability and also possess good temperature stability up to 300°C [2,4,8]. E-Glass fiber reinforced epoxy composites shows better mechanical properties in terms of tensile strength [6,23,24].…”

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%.
