Abstract

In this paper the radial stiffness associated with stacking sequence effects, and the dimensional stability issue associated with thermally induced surface deformation in quasi-isotropic laminates due to the effect of stacking sequence and additional resin layer technique, are numerically investigated. Finally, the influence of surface resin layer techniques for fiber print-through mitigation in a composite mirror is tested for evaluation of surface accuracy across varying thermal conditions.

본 논문에서는 단방향 섬유복합재료를 사용하여 만든 준등방성 라미네이트 반사경내의 표면정밀도 문제에 대하여 기술하였다. 복합재 반사경내의 방사형 방향의 굽힘강성계수의 변화로 발생할 수 있는 국부적 표면변형의 형상/패턴 및 반사경 표면에 섬유패턴 효과를 감쇠시키기 위해 추가 수지층이 도포된 반사경에 온도변화 발생시 굽힘강성의 불균일성으로 인하여 발생하는 표면의 굴곡을 수치해석과 실험으로 검토하고 문제점 해결을 위한 방향을 제시하였다.
