Remote Laser Processing of Composite Materials with Different Opto–Thermic Properties

Near net shape preforms with a minimum of material consumption are required to increase the acceptance of fibre reinforced polymers in the industry, This should be accompanied with appropriate, fast and flexible processes. The 21/2 D beam deflection expands the area of possible kinds of processing strategies, wherefore the laser can be a tool for the future. The development of remote laser processing is strongly connected with the understanding of the interaction between tool and material. Within the paper investigations on opto – thermic properties of the components as a function of the wavelength of the beam source were shown. The results of the measurements are fundamental for processing composite structures made of glass- or carbon fibre and polymer matrices.
