High-velocity impact characteristic of carbon fiber reinforced plastic composite at low temperature

摘要

Carbon fiber reinforced plastic composite materials have unique mechanical properties and could substitute aluminum alloys used in harsh environments. We performed high-speed impact experiments to study carbon fiber reinforced plastic fracture behavior at cryogenic temperatures for two specimens of different laminated constitution. The effect of temperature, impact velocity, and layered composition on the fracture behavior of carbon fiber reinforced plastic was examined. Perforation hole-sizes and shapes, as well as damaged regions on the specimens varied systematically depending on layered compositions. We found that carbon fiber reinforced plastic layered composition played an important role and damage regions were controllable by manipulating carbon fiber reinforced plastic layered compositions.
