Composite materials are often characterized by anisotropic mechanical properties. But also the thermal and optical behavior is orientation dependent. The knowledge about these characteristics is important when the material will be treated with high power lasers.
Lasers are flexible and wear-free tools and also suited for the processing of composite materials, if the laser ray will be absorbed at the material.
Within this paper fundamental research results will be shown, where composite materials like carbon fiber reinforced polymers were treated cyclically or simultaneously with 10,6 and 1,07 micrometer laser radiation. A laboratory setup to realize multi-wavelength remote cutting with one scanner equipment will be characterized. The cutting and ablation results will be compared with conventional remote cutting results at defined material compositions.
