Crack Propagation and Acoustic Emission Evaluation of Plain Woven CFRP Laminate Composites for Fiber Orientation
섬유방향 변화에 따른 직물구조 CFRP 적층판의 균열진전 및 AE평가
Abstract
Crack propagation and AE characteristics of CFRP plain woven laminate composites are examined with acoustic sensor by AEDSP 32/16 board in PC system. AE signals are measured during the fracture behavior tests. The purpose of study is the estimation of the crack extension behavior effected between three kinds of fiber orientation for plain woven CFRP laminate composite and the relationship between AE characteristics and load-displacement curves and crack extension length.
