摘要

Banana fibers are among the lignocellulose with great potential for use in polymer composites, such as the variety from the Musaceae family, due to its low density and high mechanical resistance. In this work, polyester matrix composites incorporated with continuous and aligned banana fibers were tested for their flexural behavior. Specimens with up to 30% in volume of fibers were bend-tested until rupture. The results showed an increase in both the composite mechanical strength and the stiffness with incorporation of these fibers. A fractographic analysis by SEM disclosed a moderate adhesion mechanism between the banana fiber and the polyester matrix. This mechanism is apparently responsible for the improved performance of the composites.
