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.

Flexible, composite thermoplastic filament which contains endless fibres

A process for preparing a composite, continuous-fiber-containing filament which entails:

Process of making a composite article

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:

Mixed-matrix composite thermoplastic and thermosetting material

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.
