    摘要: Methods of making fiber-resin compositions are described. The methods may include the providing of a thermoplastic resin to an extruder, where the thermoplastic resin may include at least one reactive moiety capable of forming a covalent bond with a coupling agent on a plurality of reactive fibers. The methods may further include combining the thermoplastic resin with the plurality of reactive fibers also supplied to the extruder. The reactive fibers are sized with the coupling agent that reacts with the thermoplastic resin to form the fiber-resin composition, which may be extruded from the extruder. Methods of making fiber-reinforced composite articles from the fiber-resin composition are also described.

    摘要: Methods of making a fiber-reinforced composite are described. The methods may include applying a sizing composition to a plurality of fibers to make sized fibers, where the sizing composition may include at least one of a curing agent or an accelerator for a resin composition. The sized fibers may be contacted with the resin composition to form a resin-fiber amalgam, where the resin composition includes 50 wt. % or less of a total amount of the curing agent and the accelerator that is also present on the sized fibers. The resin-fiber amalgam may then be cured to form the fiber-reinforced composite.

    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.
