Winding angle affects crash performance of lightweight carbon fibre tubes.
Carbon fibre-reinforced polymer (CFRP) tubes were tested to see how the angle of winding affects their ability to absorb energy during a crash. Tubes wound at different angles were compressed slowly to see how they performed. The results showed that as the winding angle increased, the tubes became less effective at absorbing energy. Tubes wound at ±45° had the highest energy absorption capacity. This study helps us understand how the way CFRP tubes are made can impact their crashworthiness.
