Abstract: Legacy epoxy resin and carbon fiber systems have been key to achieving where the general composite industry is today, however new emerging applications require increased performance at higher temperatures. This requires new optimized product systems incorporating organic high temperature matrices that can operate from 230°C to over 500°C. Characterization of candidate composite systems with optimized fiber/matrix interface, fiber sizing, and effects of processing cycle on material performance as well as the generation of reliable initial data will all contribute to a comprehensive understanding of material behavior for a wider operational range. This foundation is critical for the continued advancement of these ultra-high performance material systems into future operational platforms. Toray Advanced Composites (TAC) is exploring the integration of U.S. domestically produced T800 and T1100 Toray fibers with surface treatments and sizings tailored to optimize performance with several high temperature (HT) Toray resin systems. These systems include bismaleimides (BMI), high temperature cyanate esters (CE), and polyimides (PI) to give the operational user a wider platform for material design trades. Incorporating these HT resin choices with the most advanced ultra-high strength (UHS) intermediate modulus (IM) and intermediate modulus plus (IM+) carbon fibers will maximize the elevated temperature strength performance benefit. As part of this integration, HT resin systems were evaluated with variants of an IM T800 carbon fiber as well as IM+ T1100 reinforcement into a standard TAC unitape format. Initial mechanical screening properties included axial tension, compression, short beam shear at room temperature dry (RTD) conditions. Glass transition temperature (via DMA) and char yield (TGA) were also evaluated as an indicator of HT property retention. The properties derived here provide a baseline for high temperature testing and can be tailored to the specific end-user and application. The data available herein can be used to inform designs and expedite the transition to higher MRL/TRLs for rapid insertion into other programs.
