Dynamic mechanical and fracture morphology of kevlar fiber filled groundnut reinforced epoxy composites

Abstract

Abstract The present study deals with the synthesis and characterization of Kevlar fibers produced by a condensation reaction of para-phenylenediamine with terephthaloyl chloride. The composites were fabricatedusing a 5 % KFs fiber loading for groundnut/epoxy at varied filler loadings by means of hand lay-up. We have evaluated dynamic mechanical properties such as the tensile, flexural and impact strength ofgroundnut/epoxy composites reinforced with Kevlar fibers. All the dynamic mechanical properties were performed as per the essential American Society of Testing and Methods standards. The Groundnut/epoxy hybrid composite reinforced with synthesized Kevlar fibers has a high tensile, flexural and impact strength. A composite treated in this manner has high dynamic mechanical properties which make it suitable for a number of applications in engineering industries.
