Fibra de mocora como refuerzo de resina poliester para aplicaciones mecánicas

Abstract

INTRODUCTION. The reinforcement of resins with natural fibers is used worldwide and due to the biodiversity of Ecuador it’s natural origin fibers would suppose a contribution to the manufacture of parts as composite materials. OBJECTIVE. Characterize the mocora fiber as reinforcement of unsaturated polyester resin, determine the properties of the material and find the viability of applications in the mechanical area. METHOD. This research begins with the collection and documentation of fiber information. Characterization of the fiber taking measurements, performing microscopy, SEM, analysis of moisture absorption, observation of the reaction of the fiber with the resin, mechanical characterization of the composite material, designing molds for test pieces and mechanical tests based on ASTM standards. RESULTS. It is shown that the fiber has different lengths in 90º orientations with a coating, the fiber has impermeable layers and internal grooves, has an average moisture absorption of 61%, the wood mold resists the pressure, there is encapsulation of the fiber, but It hasn’t wettability with polyester resin. DISCUSSION AND CONCLUSIONS. The mold obtains samples without spills, but the fiber is unfeasible as a composite material under natural conditions, suggesting future investigations with enzymatic treatments to the fiber.
