Energy Absorption Characterization of Composite Tubes for Railway Application

초록

In this study, the failure modes and energy absorption characterization of four different kinds of circular tubes made of carbon, glass, Kevlar and carbon-Kevlar hybrid fibres composites with epoxy resin have been evaluated. These tubes were fabricated with unidirectional and woven fabric tape. The woven fabric carbon/epoxy tubes absorbed more energy than others. In case of carbon-Kevlar/epoxy tubes fabricated from unidirectional tape, [90K/0C] tubes failed in a local bucking mode and showed good post crushing integrity whereas [90C/0K] tubes failed in a lamina bending mode and bad post crushing integrity
