Static and dynamic mechanical behavior of intra‐hybrid jute/sisal‐reinforced polypropylene composites: Effect of stacking sequence

Abstract

In the current research investigation, jute and sisal intra‐hybrid woven fabric were specifically tailored to maintain jute and sisal in weft and warp directions, respectively. Jute sisal intra‐hybrid composites were prepared with four layers of intra‐hybrid woven fibers using a compression molding technique. Physical, mechanical (static and dynamic), and thermal stability behavior were investigated, and their structure–property relationship has been established. The obtained results showed that jute‐sisal cross‐interplay‐based hybrid composites recorded maximum tensile and flexural modulus values with minimum anisotropy. It can be concluded from the current experimental investigation that weft/warp orientation and stacking sequence play a significant role in defining the mechanical performance and anisotropic nature of woven fiber‐reinforced laminated composites. Also, the anisotropic properties can be minimized by investigating the effect of fiber orientation and hybridization of natural fibers‐based laminated composites.Highlights Woven mats were tailored to orient different fibers in warp and weft directions. The influence of the fiber's orientation and stacking sequence was analyzed. Fiber orientation and hybridization have influenced mechanical performance. The alternative stacking sequence has shown the highest mechanical properties.
