eiss et al of Friedrich-Alexander University of Erlangen-Nuernberg, Germany developed a vibration-assisted hot melt bonding technique was developed with short cycle times using the technology from vibration welding. It is suitable to join thermoplastics with thermoset materials or thermosets using a thermoplastic interlayer, by taking advantage of short cycle time and good lap shear strength. (RDC 12/16/2010).

Thermoplastic vibration welding: Review of process phenomenology and processing–structure–property interrelationships
(1–22)Polymer Engineering & Science 51 #1 (2011)
Patham and Foss of General Motors of India and Michigan describes vibration welding which offers a robust method for physically joining thermoplastics to fabricate complex hollow assemblies from simpler injection-molded articles without using an external heat source, adhesives, or mechanical fasteners. Vibration welding involves a complex interplay of several phenomena—solid (Coulomb) friction, melting, high strain-rate, pressure-driven, strong (high-strain) melt flows, solidification, and microstructure development—which ultimately govern the strength and integrity of the weld. The interrelationships between the microstructure in the weld region and the resulting weld strength and fatigue behavior are then discussed in the light of this phenomenological information for neat polymers, filled polymers, polymer blends, and foams.(RDC 2/2/2011)
