Abstract:
Nowadays, there is a constant concern to develop products that are environmentally friendly. This is largely due to the constant threat of oil shortages, the emission of greenhouse gases and inadequate waste disposal. In view of this urgency for the development of alternative products to those of synthetic origin and increasingly sustainable, composite materials reinforced by vegetable fibers have emerged, consisting of a polymeric matrix and reinforcement, the latter of natural origin. The use of polymer composite materials reinforced by natural fibers has advantages and disadvantages. The main advantages are the greater lightness of this material, the reduction of greenhouse gas emissions and the reduction of the carbon footprint. And as disadvantages, they present poor interfacial adhesion between the matrix and fibers and high moisture absorption. The study of these advantages and disadvantages makes it possible to investigate properties in the natural fiber composite based on technical standards, such as ASTM D3039 used for the tensile test of the material, thus obtaining resistance and elastic modulus values. Therefore, promising results in the use of natural titic vine fiber as reinforcement in epoxy matrix polymer composites were obtained, showing an improvement in tensile strength with the incorporation of natural fiber into polymer resin, mainly for the volumetric fraction of 70% of reinforcement.
