Investigation and Fabrication of Thermo-mechanical Properties of Ceiba Pentandra Bark Fiber/Poly (Vinyl) Alcohol Composites for Automobile Dash Board and Door Panel Applications

In the present study, Ceiba pentandra bark (CP) fibers, owing to their low weight-to-high strength ratio and recyclable features have been selected as reinforcement in thermoplastic polymer. i.e., poly (vinyl) alcohol (PVA) for fabrication of composites to find its application in automobile dash boa...

description In the present study, Ceiba pentandra bark (CP) fibers, owing to their low weight-to-high strength ratio and recyclable features have been selected as reinforcement in thermoplastic polymer. i.e., poly (vinyl) alcohol (PVA) for fabrication of composites to find its application in automobile dash board and door panel. The bark fibers were chemically modified with NaOH to enhance its bonding property with hydrophobic polymer. The mechanical properties increases at the early stage with the increase in fiber content till optimum (20 wt% of fiber) fiber loading following that it declines. The mechanical properties obtained at optimum fiber loading are 98.49 MPa of flexural strength, 32.01 kJ/m2 of impact strength, 85.92 MPa of tensile strength and 98.49 MPa of flexural strength. The composites were further characterized by thermogravimetric analysis (TGA), dynamic mechanical analysis, and scanning electron microscopy for analysis. The thermal stability of the composites increased as compared to neat PVA matrix which was concluded by TGA. 20 wt% fiber content composites were found to be highly suitable for making dash board and door panels by automotive industries as it reveals better mechanical as well as thermal properties compared with other fabricated composites.
