A method of forming members of fiber reinforced thermoplastic members via molding, the members including at least one hollow chamber, formed by water injection into the melt in the mold, to stiffen the finished member. The thermoplastic is preferably selected from a group comprising polypropylene, Nylon, PET, ABS, TPO, and thermoplastic polyurethane, while the reinforcing fibers are preferably selected from a group comprising glass, aramid, carbon, and natural fibers. Preferably, the extruded melt is produced such that the average length of the reinforcing fibers is less than four millimeters.

L'invention concerne un procédé pour former des éléments appartenant à des éléments thermoplastiques renforcés par fibres, à l'aide d'un moulage. Ces éléments comprennent au moins un compartiment creux formé par une injection d'eau dans la matière en fusion, dans le moule, pour rigidifier l'élément fini. La matière thermoplastique est de préférence sélectionnée dans un groupe comprenant: polypropylène, nylon, PET, ABS, TPO et polyuréthanne thermoplastique, tandis que les fibres de renforcement sont de préférence sélectionnées dans un groupe comprenant: verre, aramide, carbone et fibres naturelles. De préférence, la matière extrudée est produite de sorte qu'une longueur moyenne des fibres de renforcement est inférieure à quatre millimètres.
