Fibrous plants are renewable resources that are abundant in nature. Economically and ecologically, it is especially advantageous to create high-performance composites using inexpensive natural fibres like water hyacinth (Eichhornea crassipes). As a composite matrix, remarkable thermosetting resins like polyester are frequently utilized because polymer composites have excellent dimensional stability, thermal stability, and mechanical qualities. For this investigation, hot curing and solution impregnation procedures were used to create several composites from water hyacinth fibre and polymer. This study's objective is to ascertain how the textures alter when PVC and bio composite components are included. This research is being done to find out what changes polymer materials with fiber-reinforced nanoparticles make. This study uses the water hyacinth (Eichornia crassipers) as a bio-composite material. This type of water hyacinth is usually only seen when the rivers are overflowing. The crystallinity index of water hyacinth fibre composite is 54.82%. The outside of the hyacinth composite is examined under a transmission electron microscope. Hyacinth fibre composite heat degradation is measured using the thermo gravimetric research technique. Additionally the result of this study is to find mechanical, chemical resistance, and morphological properties.
