Effects of the liquid natural rubber (LNR) on mechanical properties and microstructure of epoxy/silica/kenaf hybrid composite for potential automotive applications

Abstract The effects of rubber toughened epoxy/silica/kenaf composites on mechanical properties and microstructure were investigated. In this study, a combination silica, liquid rubber, epoxy was used to toughen epoxy/kenaf composite for potential automotive applications. with various MG30 (LMG30) contents from 1 7 phr fabricated by using hand lay-up method tested according ASTM standards testings, which impact flexural tests. modified fracture surfaces the test characterized scanning electron microscopy (SEM) study surface interaction. addition part per hundred resin (phr) LMG30 in exhibited highest strength, 13.83 kJ/m2 62.2 MPa, respectively. SEM analysis proved that helped lowering stress transfer resulted optimum yielded has high be
