▎ 摘  要

NOVELTY - Manufacturing fiber reinforced polymers using fast curing epoxy resins involves producing a powder resin comprising a polymer precursor and a thermal initiator. A fiber structure is packaged with the powder resin, resulting in a resin-packed structure. The resin-packed structure is heated to a curing temperature high enough to melt and cure the resin-packed structure to form a final structure. USE - Manufacturing fiber reinforced polymers using fast curing epoxy resins, where polymers are used for fabrication of lightweight structures. ADVANTAGE - The Fiber Reinforced Polymers (FRPs) made by solid epoxy has clear advantages from using solid oligomer epoxy instead of liquid monomer, including higher crosslink density from the use of novolacs epoxy. Finally, due to the controllable viscosity from heating and short path length, using solid resin allows high filler loading of the fibers. This increases the performance of FRPs.
