  • Flexible, composite thermoplastic filament which contains endless fibres and process for preparing it
    Patent number: 5747137
    Abstract: A flexible, composite, thermoplastic filament, which contains continuous fibers, and which filament contains a flexible sheath of a thermoplastic polymer which coats a fiber bundle of fibers, which fiber bundle is impregnated with a thermoplastic powder, which is made of the same thermoplastic polymer coating the fiber bundle, wherein the filament has a substantially elliptical cross-section.
    Type: Grant
    Filed: November 6, 1995
    Date of Patent: May 5, 1998
    Assignees: Eniricerche S.p.A., Enichem S.p.A.
    Inventors: Domingo Cutolo, Erminio Zoppi
  • Process of making a composite article
    Patent number: 5614139
    Abstract: A process for preparing a composite, continuous-fiber-containing filament which entails:a) unwinding a continuous fiber bundle from a bobbin,b) loosening the fiber bundle, in order to separate the bundle substantially into individual fibers,c) impregnating the individual fibers with a thermoplastic polymer powder, andd) recompacting the fiber bundle and providing a flexible sheltering sheath around the bundle, whereby the fiber bundle is caused to have a substantially elliptical cross-section.

  • Mixed-matrix composite thermoplastic and thermosetting material reinforced with continuous fibres
    Patent number: 5380583
    Abstract: A mixed-matrix composite material reinforced with continuous fibre comprising a flexible sheath of thermoplastic polymer covering a multifibre filament impregnated with a powder consisting of:1-99% by weight, and preferably 50-95%, of a thermoplastic polymer;99-1% by weight, and preferably 50-5%, of a reactive monomer and/or prepolymer which on thermal stressing is able to undergo crosslinking and/or molecular weight increase.
    Type: Grant

  • Process for preparing shaped bodies of thermoplastic polymers reinforced with long fibres
    Patent number: 5362431
    Abstract: Process for preparing shaped bodies of thermoplastic polymers by means of extrusion, injection, or spin molding of granules having a length within the range of from 2 to 100 mm, obtained by cutting a continuous calendered filament constituted by a bundle of fibres impregnated with a thermoplastic polymer in powder form and coated with an outer sheath constituted by a thermoplastic polymer which is the same as, or different from, the polymer which constitutes said powder, and having a melting point equal to or higher than the powder polymer.
