摘要
A two component chemically thermoset composite resin matrix for use in composite manufacturing processes includes a solvent free polyisocyanate component and a solvent free polyol component. The solvent free polyisocyanate component is either an aromatic polyisocyanate, an aliphatic polyisocyanate or a blend of both. The solvent free polyol component is either a polyether polyol, a polyester polyol or a blend of both. The polyisocyanate component and the polyol component are in relative proportions in accordance with an OH/NCO equivalent ratio of 1:1 to 1:2. The components form a relatively low cost polyurethane composite resin having a useful range of physical properties, without the emission of volatile organic compounds during curing.
