ABSTRACT:
The present invention relates to a composite made by the process of melt mixing (a) a polymer having at least one isocyanate reactive group, wherein the polymer is from 30 to 90% by weight of the composite; (b) a thermoplastic polyurethane at from 0.1 to less than 10% by weight of the composite; and (c) a reinforcing fiber at from 9.9 to 60% by weight of the composite, wherein the sum of the weight percentages of components (a)-(c) is equal to 100%, wherein the polymer (a) is not a polyamide. The invention further relates to a composite prepared by the process of melt mixing (a) a polymer having at least one isocyanate reactive group, wherein the polymer is from 25 to 90% by weight of the composite; (b) a thermoplastic polyurethane at from 0.1 to 10% by weight of the composite; (c) a reinforcing fiber at from 9.8 to 60% by weight of the composite, and (d) an epoxy compound at from 0.1 to 5% by weight of the composite, wherein the sum of the weight percentages of components (a)-(d) is equal to 100%. The invention further relates to the methods for making the composites of the present invention. The invention further relates to articles containing the composites of the present invention.
