Effect of Fiber Length and Loading on the Mechanical Characterization of Cyperus Pangorei Fiber Reinforced Vinyl Ester Composites

Abstract

Polymer composites fabricated using plant fibers have become a dominant role in number of industries due to the outstanding results of their physical and mechanical characteristics when compared to traditional materials. The current study aims to develop lightweight and affordable composite materials using Cyperus pangorei fiber (CPF) and a vinyl ester (VE) resin matrix. Comparing the characteristics of composite materials created with different fiber lengths (3 to 11 mm) and contents (10 to 50% weight). The composite with 7mm fiber length and 40% of fiber content demonstrated the highest level of stability among the various fiber weight and lengths percentages tested. A composite system's fiber contents have a significant impact on its overall performance. The bonding of fibers and matrix of the specimens were good, according to SEM analysis. As a result, the current study suggests that the optimal CPF-reinforced VE composites would be a capable substitute to traditional materials for value-added engineering products.
