Compression resilience and impact resistant properties of fibre reinforced sandwich composites

摘要

This paper presents an experimental investigation on the compression behaviour of fiber reinforced sandwich composites. In this study, 5 different types of sandwich composites were prepared with spacer as middle layer. Also, 3 different types of woven kevlar fabric structures were used as outer layers. Sandwich composites were fabricated using epoxy resin by wet lay-up method under vacuum bagging technique. Compression behaviour, ball burst and knife penetration was tested and effect of weave type of these composites were studied using the compression stress-strain curves. We know, spacers have excellent compression elasticity and cushioning.
