Abstract
In this study, energy absorption property of braided composite pipe was investigated. The braided composite pipes with different braiding angle, the number of laminations and cross-sectional shape were produced and the relationship between the amount of energy absorption and a fracture aspect was clarified. It was clarified that energy absorption was improved under condition that fiber fracture was caused by opening the composite layers both into inside and outside without causing backing. Further, it was found that absorbed energy for bending of the composite was improved by adopting a cross sectional shape with lager moment of inertia of area and aligning the fiber bundle in the circumferential direction.
