Abstract

This article presents investigations into the weldability of high-performance polymers and carbon fiber reinforced thermoplastics (CFRP) using laser transmission welding techniques. Fundamental studies of the absorption characteristics of CFRP as joining partner and the heat distribution within the surface due to laser impact have been performed. The welding process has been analyzed with respect to the properties of the weld seam and lap shear strength tests have been realized for different material combinations.
