Abstract:
1. A method of forming a fiber reinforced polymer composite comprising: impregnating continuous fibers with a resin system; pulling the resin-impregnated fibers through a die; and at least partially solidifying the resin system in the die; wherein the resin system comprises nanoparticles and a curable resin; wherein the nanoparticles are present in an amount of 0.5 to 8 wt. % of the resin system; wherein the nanoparticles are selected from surface-modified silica nanoparticles and surface modified calcite nanoparticles having a silica or calcite core and a reactive surface modifying agent associated with the core; wherein solidifying the resin system comprises reacting the curable resin with the reactive surface modifying agent; and wherein the fiber reinforced polymer composite comprises at least 66 volume percent of the continuous fibers.
