MODIFIED RESIN SYSTEMS SUITABLE FOR LIQUID RESIN INFUSION

摘要

A curable composition for liquid resin infusion (LRI) and a manufacturing process for producing a molded article. The curable composition includes:
a) no more than 5.0 wt % of a thermoplastic polymer;b) no more than 5.0 wt % of nano-sized core-shell particles;c) no more than 5.0 wt % of nano-sized inorganic particles;d) an epoxy resin component; ande) one or more amine curing agent(s),

wherein the initial viscosity of said curable composition is no more than 5 Poise at a temperature within the temperature range of from about 80′ C. to about 130′ C.
