Although knowledge about the laser processing of CFRP is continuously increasing, deeper process knowledge is of importance for the development of automatable and controllable industrial processes. Furthermore,
CFRP [6]. V. Tagliaferri [7] proposed that the width of the upper surface cut (kerf width) could be one of the indicators to evaluate effective utilization rate, accuracy, and removal efficiency, which are important parts of processing quality. Both continuous wave and pulsed laser generate ...
By setting stepped process parameters, the method sequentially completes the separation and cleaning of the CFRP layers, recovering carbon fibers that retain their original weave structure in just 147 s. The study delves into the characteristics of the products from the rapid laser pyrolys...
The implementation of CFRP is limited by the lack of automatable, reliable and costefficient processing. One main research focus within the field of laser processing of CFRP is the influence of laser and process parameters on the process quality. In terms of laser cutting, the extent of the ...
To reduce the thermal effect of laser processing CFRP, this paper investigates the use of siphoned water mist to cool the material. This involves directing a water mist jet at the CFRP, which forms a flowing water film on the surface. The droplets in the mist evaporate and convectively ...
A taper of approximately 0.3 was achieved with a combination of 99 W, 50 mm/s, 13 ns and 1500 kHz. The experiments indicate that laser power and pulse width are crucial factors that affect the quality of micro-hole processing. However, nanosecond laser drilling can result in thermal damage...
The results reveal that the CFRP composite plate could be rapidly drilled with highly qualified processing surface by the nanosecond short-pulsed laser with rotary drilling method. The figures such as circle, square, triangle, and regular hexagon could be processed with minimum hole...
CFRPLaser machiningRaman spectroscopyWe aim to develop a high quality laser processing technology for CFRPs using a pulsed laser at a wavelength of 258nm. We previously reported high aspect ratio (>80) laser cutting with no heat-affected zone (HAZ) and high-speed laser piercing for 1.6mm ...
SUPERIOR CRACK BEHAVIOR OF CFRP PROCESSED WITH NANOSECOND UV LASER PULSES: Paper Number Macro #501We aim to develop a high quality laser processing technology for CFRPs, we focused on UV laser pulses. We previously reported high aspect ratio (>80) laser cutting with no HAZ and high-speed ...
Furthermore, the operation is cumbersome while processing fine patterns and tends to damage fabric with low thicknesses. Hence, it is of great necessity to develop a better method to improve laser cutting for non-woven fabric. In this study, a UV nanosecond pulsed laser with a wavelength of ...
