Abstract

The design of composite joint is a very important research area because they are often the weakest areas in composite structures. In this paper, the failure load of the mechanically fastened composite joint with the clamping force was predicted by the failure area index method. By the suggested failure area index method, the strength of the mechanically fastened composite joint could be predicted within $22.5\%$ when the clamping force was applied to the composite joint.

복합재 구조물에서 체결부위는 매우 취약한 부분이므로 복합재료 체결부에 대한 설계는 중요한 연구분야로 대두되고 있다. 본 논문에서는 클램핑 포스가 존재하는 복합재료 기계적 체결부의 파손강도를 파괴면적지수법으로 예측하였다. 클램핑 포스가 존재하는 기계적 체결부의 파손강도를 파괴면적지수법으로 예측한 결과, $22.5\%$ 범위 내에서 체결부의 강도를 예측할 수 있었다.
