Removal of polymer matrix material of fiber-reinforced plastic by laser

The business unit Microtechnology of the Fraunhofer Institute for Material and Beam Technology IWS works on selective matrix ablation of fiber-reinforced plastic (frp). A process is developed, which realizes a fiber-protecting removal of matrix material by laser. With this pretreatment it is possible to apply a rib like reinforcement structure afterwards on consolidated frp components for instance.
