    Abstract: This invention relates to a process of making a fiber-reinforced composite. Glass fibers may be provided. These glass fibers may be treated with a sizing composition that has a coupling-activator compound with the formula: S—X-(A)n, where S represents a silicon-containing coupling moiety capable of bonding to the surface of glass fibers, X represents a linking moiety, and (A)n represents one or more polymerization activator moieties. The treated glass fibers may be combined with a resin to make a fiber-resin mixture. The resin may have a monomer, a catalyst, and an activator compound capable of initiating a polymerization of the monomer. The monomer may be a lactam or lactone having 3-12 carbon atoms in the main ring. The fiber-resin mixture may then be cured so that the monomer polymerizes to form a thermoplastic polymer matrix of the fiber-reinforced composite. The thermoplastic polymer matrix may be formed by in situ polymerization initiated from both the surface of the glass fibers and the resin. The fiber-reinforced composite formed may be at least 70 wt. % glass fiber.

    Abstract translation: 本发明涉及一种制备纤维增强复合材料的方法。 可以提供玻璃纤维。 这些玻璃纤维可以用具有下式的偶联活化剂化合物的施胶组合物处理：S-X-（A）n，其中S表示能够结合到玻璃纤维表面的含硅偶联部分，X 表示连接部分，（A）n表示一个或多个聚合活化剂部分。 经处理的玻璃纤维可以与树脂组合以制备纤维树脂混合物。 树脂可以具有单体，催化剂和能够引发单体聚合的活化剂化合物。 单体可以是在主环中具有3-12个碳原子的内酰胺或内酯。 然后可以将纤维 - 树脂混合物固化，使得单体聚合形成纤维增强复合材料的热塑性聚合物基质。 热塑性聚合物基质可以通过从玻璃纤维的表面和树脂两者引发的原位聚合形成。 形成的纤维增强复合材料可以至少为70wt。 ％ 玻璃纤维。
