Abstract
The impact energy attenuation and damage characteristics of woven natural silk (WNS)/epoxy laminated composite panels were evaluated. The Samples prepared in configurations of sandwich WNS/epoxy/honeycomb, WNS/epoxy/coremat WNS/epoxy/foam and reinforced WNS/Epoxy laminate panels were subjected to low velocity impact loading at energy levels of 32J, 48J and 64J respectively. Impact parameters like load- deflection, load-time and absorbedenergy-time behaviour were measured for evaluating the impact performance in terms of load bearing capabilities, energy absorption and failure modes. Evaluation of the results showed WNS/epoxy/coremat as possessing better load bearing capability qualities. In general energy absorption decreases as impact energy increases in all the composite samples; WNS/epoxy/foam was seen as better energy absorber. Damage areas increases as impact energy increases while time to response decreases with increase in impact energy in all the configurations. SEM micrographs show mode of failure as matrix crack, delamination and fibre breakage.
