Title: ASSESSMENT OF A HIGH TEMPERATURE RESISTANCE POLYIMIDE AS A SELF-SIZING POLYMER MATRIX FOR CARBON FIBER-BASED COMPOSITES
Abstract: In addition to the requirement of maximum fiber and matrix performance, interfacial adhesion between the fibers and the matrix plays a major role in attainment of high specific properties in structural composites. High performance thermoplastics such as polyetherimide (PEI) require high processing temperatures above 300°C and prolonged mold time to obtain adequate penetration of the matrix within fiber tows. In this research, a recently developed N-methyl-2pyrrolidone (NMP) solvated polyimide (TetrimideTM, Tetramer Technologies LLC) was investigated as a self-sizing agent as well as the polymer matrix for carbon fiber-based thermoplastic composites. Mini-composite coupons were prepared by using T300 carbon fiber tow (Cytec Inc.) in NMP diluted polyimide solution. The superior heat resistance and mechanical properties of the resulting composite materials are reported.
