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.
一种用于增强塑料复合材料的高韧性纤维,该纤维选自聚酯、脂肪族聚酰胺及其组合组成的组。纤维用一种组合物处理,该组合物主要由有机官能团
硅烷和稀释剂组成,前者的用量足以使
硅烷在纤维上的重量百分比达到 0.02 至 1.0,后者可使
硅烷水解为
硅烷醇。这种纤维可用于增强由
树脂基质构成的塑料复合材料。
