The crashworthiness of W-shaped thermoplastic composite structures made from woven carbon fiber and polycarbonate was investigated. The thermoplastic composite sheets were thermoformed into W-shaped structures. The original one with flat flange parts was called W1 type, and another was called W2 type, in which the flat flange parts were trimmed out. Additionally, the stacking sequence of the composite structures was modified from [(0/90)]6 to [(±45)]6. Impact testing was conducted using a test machine with a drop weight of an impact energy of 300 J, and the specific energy absorption of the four types of specimens was compared. Finite element simulations were also performed and compared with the experimental results.
