Abstract
Abstract A high tenacity fiber for reinforcing plastic composites, the fiber being selected from the group consisting of polyester, aliphatic polyamide, and combinations thereof. The fiber is treated with a composition consisting essentially of an organofunctional silane in an amount sufficient to achieve 0.02 to 1.0 weight percent of the silane on the fiber, and a diluent which provides for the hydrolysis of the silane to a silanol. The fiber is used to reinforce a plastic composite additionally comprising a resin matrix.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
83 words
A fiber reinforced plastic composite comprising: a. a resin matrix; and b. a high tenacity reinforcing fiber selected from the group consisting of polyester, aliphatic polyamide, and combinations thereof, and treated with a composition consisting essentially of (i) an organofunctional silane in an amount sufficient to achieve 0.02 to 1.0 weight percent of the silane on the fiber, and (ii) a diluent which provides for the hydrolysis of the silane to a silanol; to enhance compatibility of the fiber and the resin matrix.
