Optimization of circular hole patterns on crashworthiness of polyurethane foam-filled CFRP rectangular tubes

This study examines the impact of hole sizes, patterns, and polyurethane foam (PUF) filling on the crashworthiness of rectangular carbon fiber-reinforced polymer (CFRP) tubes used in crash box structures. While integrating holes for connections and sensors is common, it can compromise structural int...
