Solid epoxy resins are mainly used as protective coatings e.g. in marine applications, and have had limited use as composite matrices. Solid epoxy formulations are typically much cheaper than liquid epoxy resins commonly used in composite production. The development of a novel manufacturing method with solid epoxies could therefore lower the overall cost of high performance composites. Different resins were formulated by mixing solid epoxies, hardeners and accelerators at elevated temperatures. These mixtures were then ground into uncured, resin powders. The resin powders were applied directly onto carbon fibers, which were then heated, infused with the melted resin system and cured (curing times of <10 min were achieved by using accelerators). The laminates manufactured without accelerator had competitive mechanical properties (flexural modulus, 80 GPa; flexural strength, 1270 MPa) when compared against other high-performance composites. However, the addition of accelerator led to higher void content in the matrix, which affected the mechanical composite properties. In order to prevent a high void content flow media was successfully introduced into the process.
