Structure of the shell plastic material army of fibers, 2004, or containers, in particular for the bodies of the railway vehicle

摘要

Structure as a shell made of an outer skin and of longitudinal and transverse reinforcement, manufactured by injection under vacuum by means of an external mold giving the contour and an inner mold. & br / reinforcement profiled elements are made of prefabricated sections (4) forming a core, gripped by the reinforcing fibers (5) and having at least one hollow space (6) which is parallel to the longitudinal axis and which, by overflow openings (7), allow the passage of the resin in order to impregnate the fibers of the frame (1, 5) of the profiles forming the core and / or of the outer skin. & br / , the invention may be applied to the bodywork of the vehicle, the structures of the airplane, the hulls and superstructures of the ship and to the containers.
