Tensile Failure and Buckling Load Improvement of Composite Plates With A Central Hole

원공이 있는 복합재료 평판의 인장파단 및 좌굴 하중 개선

In aerospace industry improvement of structural performance of flight structure without increasing weight has great advantage. In this study, an innovative design method to increase the buckling load and tension failure load at the same time without increasing the weight was investigated by using the curvilinear fiber format in composite plates with central hole. It was investigated how much gain can be obtained with curvilinear fiber format for the plates with different hole size and different stacking sequence.
