UV-Laser Treatment of Thermoplastic CFRP Parts for Paint Applications Open
The surface pre-treatment of a high performance thermoplastic CFRP for improved paint adhesion was investigated with a 30 W KrF UV-excimer laser (248 nm). Surface analysis showed no fiber release or visible removal of the thermoplastic mat…

Heat Accumulation-Induced Surface Structures at High Degrees of Laser Pulse Overlap on Ti6Al4V Surfaces by Femtosecond Laser Texturing Open
In this work, femtosecond laser pulses at high repetition rates were used to fabricate unique microstructures on the surface of Ti6Al4V. We investigated the influence of pulse overlap and laser repetition rates on structure formation. Lase…

Effect of re-depositions and fiber exposure on the adhesive bond strength of CFRP after UV excimer laser treatment Open
Adhesive bonding of CFRP is one major approach to join this class of compound materials with other components, e.g., metals. The necessity to clean CFRP parts after fabrication and generate a bond-ready interface without damaging the imple…

Investigation of the Microstructure and Properties of Aluminum–Copper Compounds Fabricated by the High-Pressure Die Casting Process Open
The material combination of aluminum and copper is increasingly coming into focus, especially for electrical contact applications. Investigations of different casting processes show that a significant influence for the formation of a mater…
