摘要:
Tough laminated composite material which comprise (A) long reinforcing fibers, (B) a matrix resin mixed with the long reinforcing fibers and (C1) a resin, preferably in the form of fine resin particles, forming a phase separate from said matrix resin which is localized in inter-layer zones, wherein 90% or more of said resin (C1) is localized in inter-layer zones and/or wherein the border length factor in the inter-layer zones is 2.5 or more and prepegs used to form the composite materials.
