Tackification of Textile Fiber Preforms in Resin Transfer Molding
Department of Chemical Engineering, The Ohio State University, 140 West 19th Ave., Columbus, OH 43210 Tackified textile fiber preforms are used widely in resin transfer molding (RTM) to produce aerospace-grade composite parts. To optimize the preforming process, a thorough understanding of many important material and process issues, such as fabric formability, preform dimension control, preform permeability, fiber wetting, and tackifier compatibility with the matrix resin, is essential. These issues are investigated based on a commercial tackifier (PT 500 from 3M). The results show that tackifier concentration, tackifier powder size, and the application conditions all play important roles in governing the moldability of tackified fiber preforms.
