Impact of high velocity projectile to carbon-fiber fabric and alumina-fiber fabric

摘要

Carbon-fiber fabric(s) or alumina-fiber fabric(s) sandwiched between two 2-mm thick aluminum plates, are impacted by a high velocity projectile up to 2.7 km/s. The projectile penetrates into the specimen and results in a perforation hole. Based on the observations of the hole, the following is suggested. The interface affects the shape of the holes, a punch-out hole is generated in 10 sheets of the alumina-fiber fabrics, but no clear hole is made in 10 sheets of carbon-fiber fabrics.
