VERGRÖSSERTE ZUVERLÄSSIGKEIT VON VIBRATIONSVERSCHWEISSTEN THERMOPLASTISCHEN VERBINDUNGEN
摘要
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.
