Beschreibung
Zusammenfassung:	The invention relates to a method for continuous production of a composite material profile by injection-pultrusion from at least one reinforcing fabric and at least one thermoplastic polymer having high fluidity, said method being characterized in that:i) said fabric is continuously pulled with a pulling speed of at least 0.4 m.min−1 in the course of said process;ii) the impregnation stage is performed by injection of a polymeric composition having high fluidity through the fabric;iii) the profile is then shaped with a specific thermal profile.The invention also relates to a profile obtained according to the method of the invention and a composite article comprising such a profile the curvature whereof may be modified in its curvature by bending and/or its profile by rotational molding.
