However, the rapid growth of water hyacinth not only encroaches on river beds, obstructing circulation, but also causes environmental pollution and affects domestic water sources. This research aims to take advantage of plastic waste and natural materials to manufacture composite materials and evaluate its mechanical properties. Through optical microscope (OM), Fourier transform infrared (FT-IR) to study and analyze the properties of water hyacinth fibers, evaluate the influence of water hyacinth fiber sizes on the mixing ratio between materials with matrix material and reinforcement phase on the tensile properties of treated water hyacinth fiber-reinforced polypropylene (PP) composites, comparing them with glass fiber composites, raw fibers, sample M0 containing 100% resin PP. The results show that the most optimal ratio is 95% wt PP combined with 5% wt fiber, fiber size is 5mm, which will help solve environmental problems, take advantage of waste sources, and bring technical benefits, technical and economic, contributing to the sustainable development of related industries.
