“…Furthermore it is obvious, that smaller geometrical dimensions lead to a minimized interaction time between laser and material. Previous investigations have shown, that a minimized HAZ is a result of short interaction time between laser and material . The results, given in Table are in accordance to the state‐of‐the‐art.…”

The development of appropriate processes aims to shorten the cycle time of the production of parts, based on fiber reinforced polymers. Here, the laser can be a tool for the future, because the wear‐ and tool free processing expands the area of treatment processes. But laser processing is a challenging process due to the strong differing thermo‐optical properties of fiber‐ and matrix material. The present paper shows a solution to take these limitations into account. An experimental setup is applied to combine radiation with 1 and 10 μm. Thereby, the parameter and application window is expanded by the mixing ratio of radiation with both wavelengths. The present paper will show optimized parameters for different kind of materials as a result of this novel type of processing.
