Abstract
Because Carbon Fiber Reinforced Plastic (CFRP) composite materials have exquisite mechanical properties, they become a substitute for aluminum alloys in various fields. However, they are fragile to external force from antiplane due to their strong anisotropic characteristics. To clarify the effect of inserted fiber direction on the fracture behavior of CFRPs, high-speed impact experiments under cryogenic temperature were conducted on this research. As a result, it was confirmed that variables such as temperature, impact velocity, and the fiber direction have influence on the fracture behavior of CFRPs.
