Analysis of process-induced damage in remote laser cut carbon fibre reinforced polymers

In this paper, an approach is presented that allows for a linkage between cutting process induced damage and the mechanical properties of machined structures. For carbon fibre reinforced polymers, milling remote laser processes are analysed. Open hole tensile test specimens, either milled or cut with three different parameter configurations tested. With two-dimensional heat conduction simulation, temperature field resulting from determined thus thermally quantified. Those results compared to micro-sections. The following structural analysis based on anisotropic model taking thermal pre-damage into account. purpose two modelling approaches, variables material reduction, compared. influence experimental results.
