METHOD AND APPARATUS FOR MAKING A COMPOSITE EXTRUDED PROFILE FORMED WITH THERMOPLASTIC ORGANIC MATERIAL REINFORCED WITH REINFORCING FIBRES

摘要

A process for manufacturing a composite profile based on a thermoplastic organic material reinforced by reinforcing fibres includes making a multiplicity of continuous reinforcing yarns come into contact with a thermoplastic organic material and shaping the composite profile. Continuous yarns based on continuous glass fibres and on a first thermoplastic are brought together to be parallel and at least one consolidated tape is formed by heating them, in which tape the reinforcing fibres are impregnated with the first thermoplastic. The at least one tape is introduced into a die sized to the cross-section of the profile and at least one second molten thermoplastic organic material is simultaneously introduced into the die in contact with the tape, to obtain a profile of at least one second thermoplastic organic material reinforced by the at least one tape.
