제목 Preparation and characterization of CF/PI composites by the vacuum bagging process
초록 The carbon fiber (CF) reinforced plastics (CFRP) can be maximize the advantage by applying the characteristics of CF such as high strength and lightness etc. Polyimide (PI) have been widely applied in various industries due to their excellent chemical resistance, heat resistance and high mechanical properties etc. Recently, hand lay-up prepreg and vacuum assisted resin transfer molding (VARTM) techniques have been used to fabricate CFRP for high-temperature serving environments. In this study, CF fabric was impregnated with poly (amic acid) (PAA) using hand lay-up technique. PAA was synthesized by ODA and PMDA in DMAc. The preform was sealed around the perimeter of the mold by vacuum bag and a vacuum was drawn within the mold cavity using a vacuum pump. CFRPs were prepared by thermal imidization in a near-infrared (NIR) oven. The morphological, thermal and mechanical properties of CFRPs were characterized by SEM, TGA, flexural strength and izod impact strength.
