Abstract

Recently, research activities are oriented towards natural fibers that seem to be the best candidate to replace synthetic fibers (i.e., carbon, glass, and Kevlar). Particularly, bamboo fiber is a promising candidate in several industries due to its low cost and important specific mechanical properties. However, a limited attention is devoted to its contribution to the mechanical properties of polymer composites. Herein, the current paper reports on the finite element and micromechanical modeling of the tensile behavior of continuous bamboo fiber composites. More importantly, the experimental tensile test is performed for validation purposes. First, bamboo fibers are isolated from stems using combined mechanical and manual techniques. Composite specimens are manufactured using hand layup and compression techniques. Interestingly, the findings show that the addition of 30 wt.% of bamboo fibers drastically improves the tensile strength of the composite. SEM (Scanning electron microscope) observations of the fractured surface reveal adequate fiber-matrix interfaces indicating the good stress distribution between matrix and fibers. More, the rule of mixture model validates the experimental data due to the low void content of the considered composites. Attractively, the anisotropic finite element model correctly predicts the tensile strength of composites.
