Abstract

During the compression molding of long fiber reinforced plastics, significant deviations in fiber content have been observed. These can lead to a decrease of mechanical properties, which could ultimately lead to component failure. Experiments in compression molding with long fiber reinforced plastics in a complex structure show significant fiber jamming and decrease in fiber content in ribbed sections. The occurring Fiber Matrix Separation (FMS) during processing is assumed to be caused by intensive fiber interaction. The governing mechanisms on FMS are evaluated and a mechanistic model is applied to simulate and predict the effect of FMS during compression molding. View Full-Text
