“…Just as in the case of neat polymers and fiber‐reinforced polymers, high degrees of orientation parallel to the vibration plane are often detrimental to the weld strength. In a comparative study of hot plate welding and vibration welding of a PC/ABS blend (Shieu and Wang [85]), the hot plate welded samples developed a weld strength of about 14 MPa, while the vibration welded samples showed a weld strength of 36 MPa, which was equivalent to a weld factor of 0.8. This significant difference in weld strengths was related to the morphology of the welds, assessed through transmission electron microscopy.…”

“…The low strength hot plate welds showed a drastic change in the weld morphology at the weld interface compared to the bulk morphology, with pronounced orientation and laminar morphology near the welds. The morphology difference between hot plate welding and vibration welding observed by Shieu and Wang [85] is surprising, given the fact that vibration welding typically results in a stronger flow‐field and narrower heat affected zones compared to hot plate welding [15]. Shieu and Wang [85] do not indicate if the two welding techniques resulted in comparable flow conditions or overall penetrations.…”

Vibration welding 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. Defects in the weld region may lead to catastrophic failure of the welded assembly. In this article, the current understanding of the processing–structure–property relationships in the context of vibration welding of thermoplastics and polymer‐matrix composites is reviewed. Experimental as well as analytical methods of investigation of the vibration welding process phenomenology are presented. 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. This review is also aimed at identifying the areas requiring further investigation with regard to understanding vibration welding phenomenology and weld structure–property relationships. POLYM. ENG.

“…Although the mechanical properties of PC/ABS blends, such as tensile strength, fracture toughness etc. [7][8][9] have been widely studied, their tribological characteristics have been insufficiently reported. For example, numerous attempts to connect wear to hardness have been made [10][11][12].…”

Polycarbonate (PC) and acrylonitrile-butadienestyrene (ABS) were blended by varying ABS content. The thermal, mechanical and tribological properties of the PC/ ABS blends were systematically characterized. Increasing ABS content in the PC/ABS blends decreased thermal stability of the blends, as a result of the lower thermal stability of the ABS than that of the PC. Although the tensile strength of the PC/ABS blends apparently decreased with increased ABS content, the PC/ABS blend with 10 wt% of ABS had the highest tensile strength, because of improved processability of the blend. The friction and wear of the ABS measured against a steel ball of 6 mm in diameter were higher than those of the PC. As a result, a higher ABS content in the PC/ABS blends resulted in higher friction and wear of the blends. The scratch results showed that scratching with a 5 mm steel ball generated a scratch with a shorter length and lower depth on the PC than on the ABS, which indicated better scratch resistance of the PC. Therefore, the PC/ABS blend with 50 wt% of PC had better scratch resistance than the ABS, due to the influence of the PC embedded in the blend.

“…After Elastic stage, the figure gives two totally different curve tendencies. The curves have Yielding stage when the failure is break in the base polymer around joints, and the loads become slightly decreasing until the specimen failure [6]. While the failure emerges as joints lapped area pulled apart, the curves step in Damage stage directly which have a sharply decrease with the increasing loads.…”

ABSTRACT Dissimilar materials jointing is an increasingly important method to get lightweight construction in the development of nowadays manufacturing industry. In this article, ABS plastic and Q235 steel overlap jointing was achieved by means of RSW (Resistance Spot Welding). we studied the effects of the main process parameters, welding current, welding time and electrode force, on joint shaping and strength, and the result showed that in the range of 0.9kA~1.3kA, 4~6s, 0.1~0.4Mpa, elegant and strong lap joints were obtained. With the heat input getting higher, the effective lap area of joint become larger and the strength are improved, whereas the high input makes the welding joint shape worse and deformation in ABS get aggravating critically. Besides, Ultrasonic Assistance was used in experiment to aid welding process based on its high-frequency ultrasonic vibration, which made joints shaping better and improved tensile strength visibly contrast to joints with the same lower heat input parameters.
