Numerical Simulation of The Over-braiding Process.

Braiding is one of the oldest textile manufacturing technologies. It is a suitable process for manufacturing reproducible preforms for resin transfer molding. The method provides a fast fibre lay-down due to the simultaneous fibre deposition. The highly interlaced structure of braids makes it possible to cover components with sharp curvatures and non-circular cross-sections, varying along the length of the component.

Important parameters characterizing yarn alignment are the braiding angle and the spacing between the yarns. The prediction of these parameters is not straight forward due to the high number of process parameters and the arbitrary geometric shape of the braided part. Furthermore, these process parameters also need to be adapted to achieve certain preform properties. Thus, a numerical simulation of the braiding process is necessary. It is a promising method to avoid time-consuming and cost-intensive braiding tests with subsequent analysis of the preform.
