A frictionally welded, filled thermoplastic article is strengthened by restricting lateral flow of molten material out of the gap between the workpieces, so that a molten pool of substantial depth is maintained from the beginning of melting to the onset of solidification. The restriction to lateral flow of material is provided by dams (projections) of essentially rectangular cross-section at each lateral edge of one of the workpieces, while the other workpiece has a substantially flat mating surface.
L'invention concerne un article thermoplastique chargé, soudé par friction, renforcé par restriction du flux latéral de matière fondue en-dehors de l'espace situé entre les pièces à souder, de façon qu'un bain de fusion de profondeur importante soit maintenu du début de la fonte au début de la solidification. La restriction du flux latéral de matière est obtenue à l'aide de barrages (projections) de section transversale principalement rectangulaire situés sur chaque bord latéral d'une des pièces à souder, alors que l'autre pièce à souder présente une surface de contact sensiblement plate.
