摩擦压力连接（FPJ）是在搅拌摩擦焊（FSW）的基础上发展起来的一种制备铝-热塑性复合材料搭接接头的方法。在连接过程中，旋转的圆柱形工具被压到铝表面上。由此产生的摩擦产生的热量被传导到结合区，导致热塑性塑料的局部软化。结合工具的轴向力和铝表面的适当预处理，产生弹性复合化合物。本文介绍了用激光对铝进行表面预处理的结果。纹理对于牢固的连接至关重要，因为它们可以显著影响有效的连接机制，例如微观和宏观形状配合。实验进行了使用不同的表面处理，通过单模激光器的接头铝（EN AW-6082 T6）和玻璃纤维增强聚酰胺（PA 6 GF 15）。该研究的目的是增加对过程行为和连接机制的理解。与以前的研究相比，采用所提出的激光表面处理，剪切强度可以提高40%。
Friction Press Joining (FPJ) is a suitable method for producing composites of aluminum and thermoplastics in lap joint configuration, which is based on modified Friction Stir Welding (FSW). During the joining process, a rotating cylindrical tool is pressed onto an aluminum surface. The resulting friction generates heat that is conducted to the bonding zone, leading to localized softening of the thermoplastics. In combination with the tool’s axial force and a suitable pre-treatment of the aluminum surface, a resilient composite compound is created. This paper presents the results of a surface pre-treatment of aluminum using laserradiation. The textures are essential for a strong connection, as they can significantly influence effective joining mechanisms, such as microscopic and macroscopic form fit. The experiments were carried out using different surface treatments by means of a single-mode laser for joints of aluminum (EN AW-6082 T6) and glass fiber reinforced polyamide (PA6 GF15). The aim of the study was an increased understanding of process behavior and joining mechanisms. The shear strength could be increased by 40 % compared to previous studies with the presented laser surface treatment.
