塑料已被用于汽车和飞机工业，以实现有效的减重。重点介绍了塑料与钢的直接连接技术，以使塑料在更广泛的应用中得到应用。在这项研究中，塑料与钢通过摩擦搭接(Flj)连接。实验材料为尼龙和聚乙烯(各150 mm×75 mm×3 mm)和普通碳钢(SPCC，150 mm×75 mm×10 mm)。SPCC固定在塑料板上，使用WC-Co工具(直径15 mm)摩擦。在恒定刀具转速下，选择了不同的连接速度，范围为200-1000 mm·min-1。Flj技术使6尼龙能够直接连接到SPCC上。然而，不能实现聚乙烯与SPCC的有效连接。对于6尼龙/SPCC接头，当连接速度为600℃·min-1时，拉伸剪切强度最大，拉伸剪切断裂发生在6尼龙基体上。对连接速度为600 mm·min-1的6尼龙/SPCC接头的断面微观结构分析表明，该接头具有良好的界面结合性能。
Plastic has been used in the automobile and aircraft industries to achieve effective weight reduction. Direct joining technique of plastics to steel is focused so as to use plastics in a wide range of applications. In this study, plastics were joined to steel via friction lap joining (FLJ). Experimental materials were 6nylon and polyethylene (150 mm × 75 mm × 3 mm each), which were selected as plastics, and plain carbon steel (SPCC, 150 mm × 75 mm × 2 mm). SPCC was fixed on a plastic plate and frictionized using a WC-Co tool (15 mm diameter). Different joining speeds, in the range 200–1000 mm · min- 1 at constant tool rotation speed, were selected. The FLJ technique enabled the direct joining of 6nylon to SPCC. However, effective joining of polyethylene to SPCC could not be accomplished. In the case of 6nylon/SPCC joints, the maximum tensile shear strength was obtained with a joining speed of 600 mm · min- 1, and fracture in the tensile shear test occurred in the 6nylon matrix. Favorable adhesion at the 6nylon/SPCC interface was observed by cross-sectional microstructure analysis of the joint with a joining speed of 600 mm · min- 1.
