摘要： A thermoplastic prepreg includes a web or mesh of fibers in which the web or mesh of fibers includes chopped fibers. The thermoplastic prepreg also includes a thermoplastic material that fully impregnates the web or mesh of fibers so that the thermoplastic prepreg has a void content of less than 5%. The thermoplastic material is polymers that are formed by in-situ polymerization of monomers or oligomers in which greater than 90% of the monomers or oligomers react to form the thermoplastic material. The thermoplastic prepreg includes between 5 and 95 weight percent of the thermoplastic material and the chopped fibers that form the web or mesh of fibers are un-bonded.

摘要： According to one embodiment, a system for manufacturing a polymethyl methacrylate (PMMA) prepreg includes a mechanism for continuously moving a fabric or mat and a resin application component that applies a methyl methacrylate (MMA) resin to the fabric or mat. The system also includes a press mechanism that presses the fabric or mat during the continuous movement subsequent to the application of the MMA resin to ensure that the MMA resin fully saturates the fabric or mat. The system further includes a curing oven through which the fabric or mat is continuously moved. The curing oven is maintained at a temperature of between 40° C. and 100° C. to polymerize the MMA resin and thereby form PMMA so that upon exiting the curing oven, the fabric or mat is fully impregnated with PMMA.

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： A curable formaldehyde-free binding composition for use with fiberglass is provided. Such curable composition comprises an aldehyde or ketone and an amine salt of an inorganic acid. The composition when applied to fiberglass is cured to form a water-insoluble binder which exhibits good adhesion to glass. In a preferred embodiment the composition when applied to fiberglass provides a sufficient blackness required in facer products.
