복합적 환경인자의 영향에 의한 접착제의 접착전단강도 및 화학구조 변화 = Effect of Combined Environmental Factors on Adhesive Shear Strengths and Chemical Structures of Adhesives

국문 초록 (Abstract)

본 연구에서는 유도무기의 탐색기에 적용되는 기존 접착제의 대체 가능성을 조사하기 위해 환경인자의 노출시간에 따른 기존 접착제와 대체 접착제의 접착전단강도들을 평가하고 이들의 화학구조 변화를 조사하였다. 이때 접착제는 기존 접착제와 대체 접착제에 대해 각각 구조용 접착제와 실링용 접착제의 두 종류를 고려하였다. 이들 접착제는 온도, 수분, 자외선 등의 복합적인 환경인자에 최대 1000시간 동안 노출시켰다. 환경인자의 노출시간에 따른 접착제의 접착전단강도를 평가하기 위해 접착전단시험을 수행하고 화학구조 변화를 조사하기 위해 ATR 적외선 분광분석을 수행하였다. 연구결과에 따르면 대체 접착제의 접착전단강도는 기존 접착제의 경우에 비해 높으며 환경인자의 노출에도 매우 안정적으로 나타나 대체 접착제는 기존 접착제의 대체용으로 적용이 가능함을 알 수 있었다.

Adhesive shear strengths of the established adhesives and the alternative adhesives were evaluated and their chemical structures were analyzed in order to investigate the possibility of replacing the established adhesives with the alternative adhesives applicable to the seeker for the guided missiles. Two types of the adhesives such as the structural adhesives and the sealant adhesives were considered. Those adhesives were exposed to the combined environmental factors consisting of temperature, moisture and ultraviolet over 1000 hours. Adhesive shear test was conducted to evaluate adhesive shear strengths and ATR FT-IR was utilized to investigate chemical structures. According to the results, the adhesive shear strengths of the alternative adhesives revealed higher than those of the established adhesives. Also the alternative adhesives were more stable to the combined environmental condition than the established adhesives. Therefore, it is found that the established adhesives were able to be replaced by the alternative adhesives.
