| Research Abstract |
High-speed(around the sound velocity) impact damage in CFRP(carbon fiber reinforced plastic) laminates was characterized. First, foreign object impact tests were conducted to obtain high-speed impact damage data. Next, modeling of damage phenomena and finite element analysis were performed to simulate the damage propagation processes. Particularly, the effect of material properties on damage size and perforation limit speed was investigated numerically. In addition, damage extension simulation was conducted using a particle method and its result was compared with experiment result to confirm the validity of the method.
