AB - We aim to lower the cost of composite manufacturing by formulating solid epoxy resins. Cured solid epoxies are typically used as protective coatings e.g. in marine applications, and are in general much cheaper than the liquid epoxy resins used in composite production. The development of a cost effective composite manufacturing technique using cheaper starting materials, such as solid epoxy resins, will increase the likelihood of composite uptake in sectors where cost and feasibility have previously limited their adoption. Powdered, uncured solid epoxy resins were formulated by mixing solid epoxies, hardeners and accelerators at elevated temperature. The resulting mixtures were then ground into powders that were applied directly onto carbon fibres. The fibres were then heated, infused with the melted resin system and subsequently cured. The following laminates have competitive mechanical properties when compared against other high performance composites. The laminates have a flexural strength and modulus of 919 MPa and 70 GPa, respectively. Using the same fibre format with a liquid epoxy resin results in a composite with a flexural strength and stiffness of 940 MPa and 80 GPa, respectively. Demonstrator 3D composite panels have been produced showing that is possible to mould the laminates during manufacturing.
