Abstract
This research work examines the bending response of honeycomb core sandwich plates that have toughened and untoughened interfaces that are reinforced by using layers of Kevlar fibers. Three-point flexural strength tests were performed to determine how the interface was altered to affect the mechanical performance. The results showed that the interface toughening increases the maximum loading load and the toughness as a whole of the sandwich specimens at all loading rates considered. Failure mechanisms were studied by means of scanning electron microscopy, and the impact of interfacial reinforcement was observed. There were great improvements in kevlar reinforced specimens and the maximum load and energy absorption of kevlar reinforced specimens had improved by about 41 and 38.5 percent respectively.
