Influence of laser irradiation on the failure behavior of unidirectional fibre reinforced polymers

To increase the acceptance of fibre reinforced polymers (FRP) in the industry, near net shape preforms with a minimum of material consumption are required. This should be accompanied by appropriate, fast and flexible processes. The remote laser processing expands the area of possible kinds of processing strategies, wherefore the laser can be a tool for the future. But the development of remote laser processing is accompanied with the understanding of the interaction between tool and material and the influence of laser irradiation to the failure behavior of FRP, to which this paper contributes. An tensile test method of an adapted specimen is introduced. Hence the test method is able to allegorize to the failure mode of inter fibre fracture as a function of laser cutting parameters.
