The characteristic evaluation of high frictional resistance prepreg influencing honeycomb core crush

하니컴 코어 붕괴에 영향을 주는 고 마찰 저항 프리프레그의 특성 평가

Aircraft composite structure with honeycomb core experiences core crush problem in manufacturing. To prevent core crush additional processes are needed such as core stabilization and prepreg material tie-down and this is the cause of increasing cost. Recent study shows that high friction prepreg prevent core crush without additional process. This paper presents the analysis of high frictional material which attracts lots of interests through physical property, mechanical property and microscopic morphology and the cause of friction.
