초록

장섬유강화 열가소성 고분자 복합재료 (FRTP)의 난연성과 내약품성 개선을 위하여 polyphenylene sulfide (PPS)를 첨가한 polyamide 6 (PA6)/glass fiber (GF)의 FRTP를 제조하였다. 고점성 수지내에 보강섬유를 균일하게 분산시키고, 함침성을 높임과 동시에 보강섬유의 손상을 방지하기 위하여 섬유상 수지와 보강섬유를 분섬비동장치에서 직접 혼방시키고, 이를 압축성형하는 독특한 공정을 도입하였다. 제조된 복합재료의 유변학적 특성, 형태학적 특성, 인장 및 충격 특성, 열적특성, 난연성, 내약품성에 관한 연구를 수행한 결과 복합재료의 기계적 특성을 약화시키지 않으면서도 난연성과 내약품성을 현격히 향상시킬 수 있는 FRTP의 제조가 가능함을 확인하였다.

Investigation was carried out for the processing methods and relevant properties of FRTP prepared from Nylon 6 and glass fiber, with or without addition of polypheylene sulfide (PPS) to improve the flammability and chemical resistance. FRTP sheets have been fabricated using a special equipment so called "Fiber Cutting, Flying and Mixing Apparatus", which directly mixes Nylon 6 fibers with reinforcing glass fibers. This specially designed apparatus gives rise to improved impregnation of highly viscous Nylon 6 resin into reinforcing glass fibers, resulting in high dispersion of the fibers without damage in the matrix. Specimens were fabricated according to the prescribed experimental design, in order to examine their mechanical, rheological, thermal properties as well as morphology, flammability and chemical resistance.

Keywords:Fiber commingling;PA6/GF composite. PA6/PPS blend;morphology;rheology.
