Caracterización mecánica de un material compuesto con fibra natural de banano y resina de poliéster para la aplicación en una moldura del panel del optra 1.8.

Abstract

The following research work studies the mechanical characteristic of the material composed of a polyester resin matrix and a reinforcement such as banana fiber with two types of configurations in which we use 5% and 25% fiber respectively, mechanical tests As the results of the standard ASTM 3039 and 7246, To do this, an applied methodology is used, thus seeking a material that replaces the conventional ones, which responds to the requirements of the original material, with the results are determined the probabilities with greater amount of fiber presents the best mechanical characteristics, the values in the test of the traction in its maximum effort is of σmax = 11.22 MPa and an E = 138.20 MPa. Continue to use the CAD in the software Inventor of Autodesk with the characteristics of the original molding, for further simulation, obtaining safety factors greater than 1, therefore, the compound with the highest amount of fiber is suitable for the elaboration of the dashboard panel molding in the Chevrolet Optra1.8.
