摘要

The developing nature of global society largely demands on heavy weighted, fossil fuel–based petro-chemical products, which create pollution and harming the biodiversity. Thus, research scholars and scientist are producing new lightweight composite material over the decades. Among those composites, the polymer biocomposite is getting attention in recent years, due to their light weight, cost effective, corrosion resistance, and high strength to weight ratio. The present research also aims to investigate the bio-based polymer composite; using polyester matrix natural bamboo fiber cassava biomass extracted biosilica particle has reinforcement. The study found that reinforcement of biosilica particle from the waste biomass into composite enhances the mechanical, thermal conductivity, and wear properties of the composite, and it makes a novelty to this study. Using such basic raw material, the composite material is fabricated under hand layup method. The prepared composite is tested after post curing process. In accordance to the ASTM (American Society for Testing and Materials) standard, the composite material is tested; the mechanical, wear, thermal conductivity, water absorption tests are carried out. The composite material (A5) reinforced with fiber of 40 vol.% and biosilica particle of 5 vol.% shows maximum tensile, flexural, impact, and hardness properties of 139 MPa, 165 MPa, 5.98 J, and 86 shore-d respectively, and tensile modulus of 5.5 GPa, 6.05 GPa, and 6.9 GPa and flexural modulus of 12.78 GPa, 13.4 GPa, and 15.27 GPa against to A1. In addition, the thermal conductivity, specific wear rate, and coefficient friction properties and water absorption properties also increased to 0.956 W/Mk, 0.005 mm3/Nm, and 0.48 respectively, with same 5 vol.% biosilica reinforcement. Thus, the active reinforcement of biofiller and bamboo natural fiber provides strength features to the composite material. Due to such high-performance features, the polymer biocomposite is utilized in areas such as automobile, aviation, defense, biomedical, and various industrial applications.
