FIBER REINFORCED COMPOSITES MADE WITH COUPLING-ACTIVATOR TREATED FIBERS AND ACTIVATOR CONTAINING REACTIVE RESIN |
摘要 |
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. |
