Process for preparing shaped bodies of thermoplastic polymers reinforced with long fibres.

摘要

Process for preparing shaped bodies of thermoplastic polymers by means of the extrusion, injection molding, spin molding of granules having a length comprised 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 of said powder polymer.
