Abstract: A thermally conductive curing process adds conductive additives to create pathways for dissipating heat during a curing process, thereby reducing the cure time, increasing the output capability, and reducing cost. Conductive particles or short fibers can be dispersed throughout the resin system or composite fiber layers in pre-impregnated or RTM-processed composite material. By disposing conductive particles or short fibers in a resin as part of the curing process, heat generated during the curing process can dissipate more quickly from any type of composite, especially thick composites. Conductive additive examples include multi-walled carbon nanotubes (MWCNTs), single-walled carbon nanotubes (SWCNTs), graphene/graphite powder, buckyballs, short fibrous particulate, nano-clays, nano-particles, and other suitable materials.
