A Study on the Fracture Characteristics of CFRP by Acoustic Emission (2)
음향방출법에 의한 탄소섬유강화 플라스틱의 파괴특성에 관한 연구 (2)
Abstract
This study is to investigate a fracture characteristics of carbon fiber reinforced plastics (CFRP) under the tensile loading as a function of acoustic emission (AE) according to the frequency analysis (transient mode) and AE source location (location mode). It was found that the fracture mechanism of AE frequency analysis was a useful tool for the estimation of different type of fracture in CFRP, i.e., matrix(epoxy resin) cracking, delamitation and fiber breakage same as AE amplitude distribution.
