Abstract

Our study deals with the recycling and strain rate effects on the dynamic mechanical behaviour of polymer composites. We particularly focus our study on high impact polypropylene and talc filled high impact polypropylene. Virgin specimens have been reprocessed (extruded) from 1 to 12 times in order to evaluate the degradation due to recycling. Dynamic compression tests have been performed for different strain rates. A comparison between experimental data obtained for both materials, virgin and recycled, have been carried out. These have permitted to quantify not only strain rate sensitivity but also the degradation of the mechanical properties after the recycling. These data have been used to propose a first modeling of the yield stress, which include strain rate effects, temperature effects and recycling effects. Preliminary results of our simulations have been compared with the experimental data for virgin (none recycled) materials only and good agreements have been found.
