  • Publication number: 20210339487
    Abstract: 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.

  • Patent number: 10611094
    Abstract: An assembly method between a part made of metal material and a part made of organic matrix composite material, said method having a step of providing two parts, each including a surface to be welded, and the surface to be welded of said composite part is made up, at least partially, of an exposed portion of at least one metal insert which is partially embedded in said composite part; positioning said surfaces to be welded opposite and separated from each other; and projecting, at high speed, the surface to be welded of the metal part or the exposed portion of the metal insert, onto one another, to obtain high-speed clamping to one another and to obtain a weld between the exposed portion of the metal insert of the composite part and the complementary portion of the surface to be welded.
