Abstract:

Rising environmental awareness is encouraging the development of sustainable materials from agricultural waste, such as natural fibers, which offer cost-effective and mechanically sound alternatives to synthetic counterparts. The study investigated the use of bio-composites in the automotive industry, specifically focusing on natural fiber reinforced polymer matrix composites. The research highlights the application of cashew nut shell liquid (CNSL) and flax fiber as key raw materials. It covers aspects such as fiber structure, surface treatments, mechanical properties, and real-world applications. Three different samples with varying compositions of CNSL and epoxy resin, Sample no.1 (50:50), Sample no.2 (60:40), and Sample no.3 (70:30), were fabricated and evaluated for tensile strength, compressive strength, and shear strength, co-efficient of friction, hardness, thermal conductivity, water absorption, and density. For Sample 1, the tensile strength was 5.05 MPa, compressive strength 3.895 MPa, shear strength 6.295 MPa, hardness 76 Shore-A, coefficient of friction 1.24, thermal conductivity 0.0524 W/mK, water absorption 2.34%, and density 1040 kg/m³. Sample 2 showed tensile strength of 2.99 MPa, compressive strength 9.648 MPa, shear strength 2.970 MPa, hardness 82, coefficient of friction 0.78, thermal conductivity 0.0531 W/mK, water absorption 2.17%, and density 1050 kg/m³. Sample 3 demonstrated tensile strength of 3.11 MPa, compressive strength 1.153 MPa, shear strength 3.719 MPa, hardness 69, coefficient of friction 0.71, thermal conductivity 0.0488 W/mK, water absorption 2.65%, and density 1010 kg/m³.
