PROCEDE DE FABRICATION CONTINU D'UN PROFILE EN MATERIAU COMPOSITE A BASE DE POLYMERE THERMOPLASTIQUE A HAUTE FLUIDITE

摘要

A method for the continuous production, by injection-pultrusion, of a composite material profile section (30) from at least one reinforcing fabric (14) and at least one thermoplastic polymer having high fluidity, said method comprising the following steps: • - i) said fabric (14) is pulled continuously at a pulling speed of at least 0.4 m. min-1 during said method; • - ii) the impregnation step is carried out by injecting a polymer composition having high fluidity through said fabric (14); • - iii) the profile section (30) is then shaped with a specific thermal profile. The invention also concerns a profile section (30) obtained according to the method and a composite item comprising such a profile section (30) of which the curvature can be modified by bending and/or the profile can be modified by rotomoulding.
