Abstract: To research the ballistic impact response and failure modes of carbon fiber plain woven and 2.5D woven fabric composite plates, ballistic impact tests were conducted in the gas gun employing the cylindrical projectile. The ballistic impact behavior was evaluated based on the ballistic limit velocity, total energy absorption, energy absorption per surface density, and energy absorption per thickness, and the impact damage was further analyzed by ultrasonic C-scan and CT scan. The results show that the plain woven fabric composite plates exhibit better ballistic impact performance than the 2.5D woven fabric composite plates. The plain woven fabric composite plates mainly produced delamination failure. The 2.5D woven fabric composite plates mainly produced shear stuffing failure. Compared with the 2.5D woven composite plates, the plain woven composite plates were bent and deformed obviously. A large number of fiber tensile failures caused by bending increased the energy absorption of the plate and increase the ballistic limit velocity. But the delamination led to large damage area and poor integrity of the plain woven composite plates. The 2.5D woven fabric composite plates had smaller damage area and better integrity.

Key words: 2.5D woven, plain woven, ballistic impact response, failure mode, energy-absorbing performance
