Experimental Investigation of Fire Proof Plate (Kevlar& E-Glass Fiber)

Abstract- This investigates the mechanical and thermal properties of hybrid composites made from Kevlar and glass fiber. These materials find applications in various fields including protective gear, aerospace components, and structural elements. By altering the stacking sequence of fibers and using compression molding, seven different hybrid composite plates were created. The tensile, and impact strengths in mechanical properties testing and thermal conductivity, heat deflection temperature and coefficient linear thermal expansion in thermal properties testing of produced samples were evaluated and compared using conventional testing. Mechanical tests revealed that the 8K2G plate exhibited the highest tensile strength and elongation, while the 2K4G plate showed superior impact resistance. Thermal tests revealed that 9K2G plate exhibits lower thermal conductivity, 8K2G,10K2G,7K3G plate have the higher coefficient of linear thermal expansion, 2K5G plate has the highest heat deflection temperature among the plates. These findings highlight the potential of hybridizing Kevlar and glass fiber to create materials with enhanced properties for diverse applications. Key words – kevlar fibre, e-glass fiber, epoxy ly556, hardner hy951, tensile and impact test.
