FE Analyses of the Compressive Characteristics of Carbon Fabric/Polymeric Foam for Sandwich Structure

유한요소해석을 이용한 직조 탄소섬유 발포 고분자 샌드위치 구조의 압축특성

In this paper, compressive characteristics of carbon fabric skin with polymeric foam core sandwich structure were investigated by FE analyses and compressive tests of polyurethane foam were also conducted with respect to temperature changes, which were determined by curing processes of epoxy or polyester resin to obtain mechanical behaviour of polyurethane foam. FE analyses indicated variation of parameters with respect to manufacturing pressure, which have comparatively massive effect upon mechanical properties of sandwich structures, i.e. wavelength as well as crimp angle of carbon fabric
