Study on Impact Characteristics of CFRP Structural Member According to Stacking Conditions

Abstract:

CFRP (Carbon Fiber Reinforced Plastics) is an anisotropic material which is the most widely adapted lightweight structural member. CFRP of the advanced composite materials as structure materials for vehicles has a widely application in lightweight structural materials of air planes, ships and automobiles because of high strength and stiffness. The CFRP Square members were made of 8ply unidirectional prepreg sheets stacked at different angles and interface numbers. Based on the collapse characteristics of CFRP member, the collapse characteristics and energy absorption capability were analyzed. The impact collapse tests were carried out for each section member. The purpose is to examine experimentally absorption behavior and strength evaluation depending on changes in the stacking configuration when the CFRP Square member s with different stacking configuration is exposed to separate impact velocity.
