Abstract

The hygrothermal effect on the strength of composite single-lap bonded joints were investigated. The specimens were manufactured in four different manufacturing methods and tested in three different environmental conditions. An interesting result is that the strengths of the joints in the elevated temperature and wet (ETW) conditions were found to be 11 ~ 23% higher than those in the room temperature and dry (RTD) environment. In contrast, the strengths of the joints in the cold temperature and dry (CTD) condition decrease by 8 ~ 21% compared to those in the RTD environment except for cobonded joint. The difference in the strength by testing environments is mainly attributed to the change of the material properties of adhesive by temperature and moisture. 초 록 본 논문에서는 다양한 방법으로 제작된 복합재 접착 체결부의 강도에 대한 온도 및 습 도 환경의 영향을 연구하였다. 시편은 두 가지 종류의 일체성형 방법 외에 동시접착 및 이차접착 등 총 네 가지 방법으로 제작하였고, 상온건조, 고온습도 및 저온건조 환경 등 세 가지 환경에서 강도시험을 수행하였다. 전체적으로 고온습도 환경에서의 파손강도가 상온 환경에 비해 11~23% 가량 높게 나타났고, 저온 환경에서의 파손강도는 동시접착 체 결부를 제외하고는 8~21% 가량 상온 강도보다 낮게 나타났다. 시험 환경에 따른 체결부 의 강도 차이는 환경에 따른 접착제의 물성 변화가 주 원인인 것으로 분석되었다.
