With the growing industrial demand for carbon fiber-reinforced thermoplastic polymers (CFRTPs), there is an urgent need to improve their adhesion to conventional metal substrates. In this study, the effect of plasma gas and Ar incorporation on the shear strength between CFRTP and Al was examined. Although NH₃ plasma had a greater effect on the surface properties of CFRTP than O₂ plasma, the incorporation of Ar into O₂ plasma showed a 280% improvement in shear strength relative to the untreated reference. Plasma treatment proved effective only on the CFRTP surface, with the failure mode switching from adhesive to substrate failure. Spectroscopic analyses revealed that functional groups like CO, OCO, or H₂NC were either newly generated or their quantity increased on the CFRTP surface. Additionally, CFRTP itself acts as an oxygen source, and its shear strength improved significantly under Ar plasma treatment, even without external O₂ supply.

随着工业上对碳纤维增强热塑性聚合物（CFRTP）的需求不断增长，迫切需要提高其对常规金属基材的粘合力。在这项研究中，研究了等离子体气体和Ar掺入对CFRTP和Al之间的剪切强度的影响。尽管NH ₃等离子体对CFRTP的表面性能的影响大于O ₂等离子体，但将Ar掺入O ₂等离子体相对于未处理的参比样品，剪切强度提高了280％。等离子体处理仅在CFRTP表面上证明有效，并且失效模式从粘合剂转变为基材失效。光谱分析表明，官能团如C O，O C O或H ₂N C要么是新产生的，要么在CFRTP表面增加了数量。另外，CFRTP本身可作为氧气源，即使没有外部O ₂供给，其在Ar等离子体处理下的剪切强度也显着提高。
