METHOD FOR PRODUCING POLYURETHANE TYPE COMPOSITE

摘要

A method for producing a polyurethane type composite obtained by injecting a formulated liquid comprises an organic polyisocyanate, a polyol and a curing catalyst into a mold in which a fibrous reinforcing material is previously set, followed by curing, by means of a reaction injection molding machine, characterized in that: (1) a polyol component having a hydroxyl value of 300 to 800 is used as the polyol, and (2) an organic acid salt of a tertiary amine is used as the curing catalyst.
