Flexural mechanical characterization of polyester composites reinforced with ramie fibers

Abstract

Ramie fibers have in the past decades being investigated as possible reinforcement of polymer composites. However, information is still needed on the fiber interaction with a polymeric matrix for a complete evaluation of the capacity of load transference inside the composite. The present work investigated the interaction of ramie fibers with polyester matrix through tests of strength. Separate sets containing 0, 10, 20 and 30% by volume of ramie fibers were aligned along the entire length of a mold and plates of these composites were obtained with polyester matrix. The fractured specimens were analyzed by SEM and the results showed an improvement in some properties of flexion with the incorporation of ramie fiber.
