  • Process and apparatus for producing sheet-shaped prepreg
    Patent number: 9238336
    Abstract: A process for producing a sheet-shaped prepreg includes: a fiber bundle introduction step in which tape-shaped reinforcing fiber bundles are disposed in a multilayer arrangement in the thickness direction and introduced into a die to which a molten thermoplastic resin has been supplied; a fiber bundle thickness reduction step in which each of the tape-shaped reinforcing fiber bundles is widened by means of spreading to reduce the thickness; a resin impregnation step in which the tape-shaped reinforcing fiber bundles are impregnated with the molten resin in the die; and a lamination step in which the plurality of resin-impregnated tape-shaped reinforcing fiber bundles are laminated in the die.

  • THERMOPLASTIC RESIN PREPREG, MOLDED PREFORM AND MOLDED COMPOSITE USING SAME, AND METHODS FOR PRODUCING THEM
    Publication number: 20140154472
    Abstract: A thermoplastic resin prepreg includes: a constituent element (I): 20-60 parts by weight of a thermoplastic resin (A) having a linear or branched polymer structure; a constituent element (II): 2-10 parts by weight of a thermoplastic resin (B) which is unevenly distributed to a surface site and has a melting point lower than that of the thermoplastic resin (A); and a constituent element (III): 30-78 parts by weight of reinforcing fibers.
