Abstract

Fiber reinforced composites are often manufactured using cost-effective fiber spraying processes. As quality fluctuates during manual manufacturing, a robot-based automation is advantageous. The automation could be greatly improved by a prior simulation of the material deposit to minimize overspray and to ensure a homogeneous material distribution. Even so, currently, specific simulation models for fiber spraying processes are unavailable. Thus, this paper investigates in which respect existing spraying process models are able to predict the material deposit, as they do not include variables such as fibers and compressed air. As a use case, we consider a thermal spraying model for the manufacturing of short fiber reinforced oxide fiber composites. We evaluate the model by simulating the deposit on a planar workpiece. The evaluation reveals that this model can only be applied to a limited extent. For higher accuracy, the model must consider further fiber spraying characteristics.
