MECHANICAL PROPERTIES AND PERFORMANCE EVALUATION OF RECYCLED POLYPROPYLENE AND TREATED MENGKUANG LEAVES COMPOSITES

Due to environmental friendly, light weight, low cost, renewability and adequate mechanical properties, natural fiber composite is preferred in many applications such as automotive, aerospace, civil and sports. Locally, mengkuang leaves (ML) has great potential to be used as reinforcement. However,...

The highest tensile strength was observed on r-PP/TML/MAPP composite with an improvement of 27.8%. The results also indicated that MAPP dominantly improved tensile and flexural strength while NaOH treatment dominantly contributed to improvement in tensile and flexural moduli.
