Abstract:
Sizing agent-coated reinforcing fibers include reinforcing fibers and a sizing agent containing a polyrotaxane, the reinforcing fibers being coated with the sizing agent. Provided are sizing agent-coated reinforcing fibers that provide a fiber-reinforced composite material with excellent mechanical properties, a method for producing the sizing agent-coated reinforcing fibers, a prepreg including the sizing agent-coated reinforcing fibers, and a fiber-reinforced composite material with excellent mechanical properties including the sizing agent-coated reinforcing fibers.
