Substitution of Virgin Material by Recycled Material from End-of-Life Vehicle (ELV)

Abstract:

The main objective of this study is the substitution of a part of virgin polypropylene with recycled polyolefin from part of End-of-Life Vehicle (ELV) to be used in automobile applications while respecting existing material specifications. First, the recycled plastic sources were characterized by ThermoGravimetric Analysis (TGA), Fourier Transform Infrared Spectrometry (FTIR), Differential Scanning Calorimetry (DSC) and X-ray Fluorescence. As the sources have almost the same properties, the one, with the easiest supply, was selected. During the second step, the study allows comparison of mechanical performance of several formulations with three specific additives made in two injection process conditions. A higher heat temperature and smaller dosage speed reduced the degradation of fibre glass during processing. Moreover, the additive improving the adhesion between the fibre and the polymeric matrix increased by 3% the flexural modulus. This study has enabled the elaboration of a global method coupling sampling methodology, formulation and process optimisation to substitute a virgin material with recycled plastics from ELV.
