摘要

Globally, the importance of using less dense and bio-based compound in domestic and transport vehicles applications are increased, because of reducing the usage of fossil fuel and petro chemical based product. The utilization of less dense material improves reduced fuel consumption, which eventually reduced global emission. Thus the present study developed a lightweight composite material using bamboo fiber, and barnyard millet husk extracted Bio ceramic particle. The primary goal of this research is to investigate and analyze mechanical, fatigue, creep, water absorption and wear resistance of surface modified and angle oriented bamboo fiber and varying concentrations of Si3N4 reinforced vinyl ester composites. Results observed that, composite VBS1 with 40 vol% of oriented fiber, 1 vol% of Si3N4particle shows better mechanical properties such as 178.2 ± 1.8 MPa for tensile, 225 ± 2.6 MPa for flexural, 6.32 ± 1.6 J for impact strength. On contrast, the specimen VBS2 with 3 vol% Si3N4 attained least fatigue life counts of 28,743 at 50% UTS, creep strain of 0.0040 at 5000s, 0.0089 at 10000s and 0.0190 at 15000s, wear resistance with Specific Wear rate of 0.32 mm3/Nm and Coefficient of friction (COF) of 0.26. Similarly, in terms of water absorption, the specimen VB with 40 vol% fiber shows least water absorption of 0.21% compared to filler reinforced composites. Moreover, the SEM analysis offers insignificant insights on the in depth microstructure of the composites. Due to such great benefits and properties, these composite acts as a suitable replacement to synthetic materials in various kinds of applications including outer body parts in automotive, aviation sector, construction, interior and exterior works such as furniture and kitchenware etc.
