Photonics meets textile engineering: faster CFRP

Carbon fiber reinforced polymer (CFRP) components are usually assembled using fasteners. These are typically glued into the CFRP component once it has been cured and drilled. The consortium behind the CarboLase project came up with a new method, using an ultrashort pulsed laser to drill the holes for the fasteners in the textile preform with micrometer-scale accuracy.

Momentum and velocity of the ablated material in laser

The automation in fabrication of CFRP (carbon-fiber-reinforced plastics) parts demands efficient and low-cost machining technologies. In conventional cutting technologies, tool-wear and low process speeds are some of the reasons for high costs. Thus, the use of lasers is an attractive option for cutting CF-preforms. A typical effect degrading the quality in laser cutting CF-preform is a bulged

Drilling Strategy for Thick Carbon Fiber Reinforced

The laser machining experiments were conducted to identify the potential of fiber laser machines to cut thick CFRP due to their superior laser beam quality. The results showed that choosing the appropriate drilling strategy in mechanical drilling is essential for reducing damage when drilling thick CFRP.

Laser Beam Machining

The term "laser" is an acronym for the physical effect (light amplification by stimulated emission of radiation) but is often also used to refer to the beam source. The first laser was demonstrated in 1960 by Th. H. Maiman, and it has since then been developed into various fields of applications, e.g., production engineering, medicine, measurement, science, and data recording.

Laser Micromachining

Both the laser beam profile and the performance of the beam delivery optics are of critical importance for laser micromachining applications. It is necessary for the laser output beam profile to be a single spatial mode, i.e., TEM 00, with a near-Gaussian profile in both axes, a circular shape, and a low astigmatism to realize a tight, round focal spot at the sample.
