Title (EN) IMPROVED PERFORMANCE OF VIBRATION WELDED THERMOPLASTIC JOINTS
(FR) PERFECTIONNEMENT POUR LA REALISATION DE JOINTS THERMOPLASTIQUES VIBRO-SOUDES
Abstract:
(EN) The invention provides an improved method of vibration welding of thermoplastic joints. Such welding is conducted by vibrating two fiber reinforced thermoplastic parts under pressure along their common interface to generate frictional heat to melt and fuse their surfaces together. Fibers from at least one surface penetrate both into the weld and into the other surface. As a result, the welded, fibre reinforced thermoplastic surfaces have increased tensile strength than heretofore achievable. Vibration welds of reinforced thermoplastic surfaces according to this invention achieve a maximum tensile strength as high as about 120 % of a weld formed by the unreinforced surfaces of corresponding thermoplastic materials.
(FR) La présente invention concerne un procédé perfectionné de réalisation de joints thermoplastiques vibro-soudés. On réalise un tel soudage en faisant vibrer sous pression deux pièces thermoplastiques armées de fibres, la vibration s'exerçant le long de leur interface commune de façon à obtenir par friction une chaleur faisant fondre leur surfaces qui fusionnent ensemble. Les fibres de l'une au moins des surfaces pénètrent dans la soudure ainsi que dans l'autre surface. Ces surfaces thermoplastiques armées de fibres et soudées présentent une résistance à la traction supérieure à ce qui était jusqu'à présent réalisable. Le vibro-soudage de surface thermoplastiques armées selon la présente invention permettent d'obtenir une résistance maximale à la traction d'au moins 120 % égale à celle d'une soudure formée par les surfaces non armées des matériaux thermoplastiques correspondants.
