Tensile Test of High Strength Thinner Curaua Fiber Reinforced Polyester Matrix Composite
In recent years natural fibers, especially those lignocellulosic extracted from plants, have gained attention owing to their engineering performance as polymer composite reinforcement. It was found that some of these lignocellulosic fibers, such as the curaua, ramie and sisal may reach tensile strength above 1000 MPa in association with very thin diameters. Therefore. the objective of the present work was to fabricate polyester matrix composites with the highest tensile strength possible, by reinforcing with the thinnest continuous and aligned curaua fibers. Tensile tests results of composites reinforced with 30% volume of these thinnest curaua fibers showed a tensile strength of 135 MPa, which corresponds to one of the highest strength attained for lignocellulosic fiber composites.
