Abstract
In the past two decades the specific energy absorption capability of polymer composite tubes has increased steadily by using advanced fibres and tough resin matrices. Tubes based on carbon fibres in a matrix of poly(ether ether ketone) (PEEK) have displayed the highest specific energy absorption capability, of 180 kJ kg−1. The various factors contributing to the superior performance of carbon/PEEK tubes have been identified by studying the crushing process using a step-by-step crushing method. Attempts have been made to correlate microfracture features of the crush zone with energy absorption capability. The superior performance of carbon fibre/PEEK tubes is attributed mainly to (a) the higher fracture toughness of PEEK matrix composites, (b) splitting of fronds and (c) the large number of fibre fractures.
