Abstract: The present invention relates to a process for the production of a polyurethane reinforced composite including mixing (A) a Polyisocyanate component including di- or Polyisocyanates (a) and (B) a polyol component including compounds having at least two groups reactive toward isocyanates (b), catalyst (c) and optionally further additives, to form a reaction mixture, contacting the reaction mixture with the reinforcing material at temperatures of less than 100° C. and curing the reaction mixture at temperatures of more than 100° C. to form a polyurethane reinforced composite. The catalyst (c) includes microencapsulated polyurethane catalyst which includes a capsule core, containing polyurethane catalyst, and an acrylic copolymer capsule shell. An average particle size D(0,5) of the microcapsules is 1 to 50 μm. The invention further relates to a polyurethane reinforced composite obtainable by a process according to the invention.
