Extrusion and injection moulding induced degradation of date palm fibre - polypropylene composites

The use of date palm fibres, which are an abundant by-product agriculture, as natural reinforcement in polypropylene (PP) was studied. Because odour emissions one the major challenges for fibre-based composites, emission Volatile Organic Compounds (VOC) generated at different processing steps analysed online. severest degradation on fibre morphology observed injection moulding step, but even when occurred fibres were effective PP and increased Young's modulus significantly. Generation odorous compounds caused by thermal such furfural alcohol or methyl astonishingly low during twin-screw extrusion granulation process. In coherence with evolution morphology, most critical step conclusion, a promising production composites. Adapted conditions allow minimizing VOC emissions, particular attention needs to be given optimization
