对由短纤维和热塑性塑料组成的碳纤维增强塑料与SUS 304异种材料进行了连接。材料通过串联电阻点焊连接。将电极压在金属/碳纤维增强塑料搭接接头的金属板上。通过电阻加热对SUS 304板进行加热，由于热传导，使得界面附近的热塑性塑料略微熔化。SUS 304可以直接与碳纤维增强聚酰胺和改性聚丙烯连接，但不能与聚苯硫醚连接。随着焊接电流和焊接时间的增加，接头面积增加，拉伸剪切断裂载荷也增加。另外，对SUS 304进行硅烷偶联剂处理，在提高接合强度方面也非常有效。
Dissimilar materials joining of SUS304 and carbon-fibre-reinforced plastics consisting of short fibres and thermoplastics was performed. The materials were joined by series resistance spot welding. The electrodes were pressed on the metal plate of the lap joint of metal/carbon-fibrereinforced plastics. The SUS304 plate was heated by resistance heating, causing the thermoplastic near the interface to melt slightly because of heat conduction. SUS304 could be joined directly to carbon-fibre-reinforced polyamide and modified polypropylene, but not to polyphenylene sulphide. The joining area increased with an increase in the welding current and welding time, so did the tensile shear fracture load. Furthermore, the silane coupling agent treatment of SUS304 was highly effective in increasing the joining strength.
