Abstract
The waste FRP occured in the fabrication of SMC(sheet molding compound) bathtubs and the wste polyurethane foam occured in electronic manufacture and waste insulator were applied as a soundproof and light weght, pannel in the waste FRP unsaturated polyester matrix resin composites to recycle, The effect of filler contents on the mechanical properties and interfacial phenomena of the filler and matrix on the composites was evaluated. The tensile strength of composites reached its maximum value of 82.34MPa when the filler content was 70wt%, and the more content of reinforcement is increased, the more tensile modulus was decreased. The flexural strength and modulus of composites, reinforced 70wt% with filler content, were dominant compared to the other samples to 72.5MPa, 958. 4MPa respectively. When composite of reinforced 70wt% with filler content, it was confirmed that pull out phenomena and cracks did not occur in the interface of reinforcement and matrix reisn through the SEM observation. Also, waste FRP and urethane foam were dispersed well into matrix resin as filler.

욕조 생산시 발생하는 폐 FRP와 냉장고 등 가전품과 폐단열재로부터 발생하는 폐우레탄폼을 흡음 및 경량판재로 재활용하기 위하여 불포화 폴리에스테르 매트릭스 수지에 보강하여 복합재를 제조하였다. EH한 충진제의 함량의 변화가 복합재의 기계적 물성에 미치는 영향과 기지와 보강재간의 계면현상을 관찰하였다. 충진제의 함량이 70wt%인 복합재의 인장강도는 82.34MPa로 가장 우수하였으며, 인장탄성율은 보강재의 함량이 증가함에 따라 감소하였다. 또한 굴곡강도와 굴곡탄성율은 폐FRP의 함량이 70 wt%충진된 복합재가 가장 우수하였으며, 그 값은 각각 72.5, 958.4MPa이었다. SEM관찰 결과 70wt %충진된 충진제 매트릭스 수지의 계면에서 pull out 현상이 확인되지 않았으며 균열도 발생하지 않았고, 매트릭스 수지내에 충진된 폐 FRP/우레탄폼 충진제가 잘 분산되어 있음을 확인할 수 있었다.
