Abstract

The optimum mold tool design for the consolidation of textile reinforced thermoplastic components requires the calculation of process times in development stage. A reduction of modeling effort can be achieved by homogenization of the thermal model parameters heat conductivity, specific heat capacity and density. On the example of braided hollow sections, consisting of glass-polypropylene-hybrid yarn, which includes reinforcement fibers and matrix material, the homogenization of these thermal model parameters is described. The comparison of simulated and measured temperature profiles of the consolidation process shows the applicability of this homogenization technique.
