Evaluation of the Physical and the Mechanical Properties of the High Frictional Resistance Prepreg and the Low Frictional Resistance Prepreg

고마찰저항 프리프레그와 저마찰저항 프리프레그의 물리적 및 기계적 특성평가

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
