Mechanical property analysis on bamboo-glass fiber reinforced hybrid composite structures under different lamina orders

Abstract

Natural fiber composites are playing the leading role in the recent research fields for their abundance of availability and comparable strength to weight ratio with the synthetic fiber composites. With this motivation, a low modulus fiber (bamboo fibers) hybridized with a high modulus fiber (Glass fibers) epoxy composites are taken for this work to evaluate their desirable mechanical properties. Usually strength of composite specimens is optimized by changing the ply orientation and volumetric ratio of fiber and matrix. But, in this analytics, a novel approach has been followed in which the hybrid composite laminates have been fabricated with five different lamina orders (B/B/B/B, B/G/B/B, G/B/G/B, G/B/G/G and G/G/G/G) using compression moulding machine. Various strength tests such as tensile, flexural and impact strength analyses have been performed. The strength values of the five specimens have been compared under the proposed loading conditions for choosing the better combination of hybrid composite structure exhibiting high strength. To validate the results, numerical analysis has also been made using ANSYS software.
