Abstract: A method for the hot stamping of a composite part with continuous fiber reinforcement in a thermoplastic matrix. A blank including a laminated structure of plies consisting in unidirectional tapes of fibers pre-impregnated with thermoplastic polymer is obtained. The blank is heated in the open to a temperature greater than or equal to the melting temperature of the polymer making up the matrix. The blank is then stamped.

Abstract: A laminated composite structural panel with fiber reinforcement comprising a skin with a thickness e1 and a localized reinforcement or patch. The skin is made up of a stack of fibrous plies in a matrix made of a thermoplastic polymer. The localized reinforcement or patch is joined to the surface of the skin and rises to a thickness of e2 in a direction that is locally normal to the skin, which is made up of a stack of fibrous plies in a matrix made of thermoplastic polymer. The surface of the plies that make up the patch is decreasing from the ply of the patch in contact with the skin so that the edges of the patch have a slope p greater than 0.5. The patch and the skin is joined by a weld.

Abstract: A stiffened panel and method for producing such a panel comprising a laminated skin extending in two directions, made of a resin and a continuous fibers reinforcement. A first stiffener in the form of a beam is made of a resin with continuous fibers reinforcement and extends on a first side of the laminated skin in a first direction. A second stiffener in the form of a beam is made of a resin with continuous fibers reinforcement and extends on a second side of the laminated skin in a second direction. The resins which make up the skin and the stiffeners are thermoplastic in nature and the stiffeners are closely joined to the skin by welding.
