Preparation and mechanical characterization of hybrid materials based on natural fibers, wood, and Biopoxy resin.

Abstract

This research was carried out with the purpose of obtaining and characterizing the mechanical behavior of hybrid materials, consisting of wood sheets with biocomposites formed between bioresin, modifying the natural fibrous reinforcement such as flax, jute, and fique. The preparation stage of the hybrid materials was carried out using the vacuum infusion process, commonly used in the preparation of conventional composite materials. For the mechanical characterization, five formulations were tested, combining for each system the type of fiber under ASTM D3039 standard. The results showed greater efficiency in mechanical properties such as modulus and tensile strength in systems containing fiber reinforcement with oak sheets, with the jute/oak system presenting the best mechanical performance. Density was estimated using the displacement method. The values showed an increase in density for combinations containing fiber/oak reinforcement. Likewise, it is noteworthy that the densities closest to the resin without reinforcement were obtained for the fique/oak system.
