Resumen
Composite materials are a fundamental part in the manufacture of elements in different fields of engineering, among them are those made from Glass Fiber Reinforced Plastic, which are widely used in industries such as aeronautics, naval, bodywork, civil, among others, due to their properties that combine the characteristics of fiberglass and resin. In this sense, it is important to know the mechanical properties of GRP, depending on the relationship between the base material and the reinforcement material, in order to guarantee the expected performance in each of the industries. Therefore, this paper seeks to experimentally verify the tensile mechanical properties in a composite material of polymer matrix and glass fiber and compare them with the properties provided by ANSYS Workbench software. To achieve the above, specimens of polyester resin/fiberglass composite material were fabricated at different volume fractions (10%, 20% and 30%) and then subjected to a mechanical tensile test, according to ASTM D3039 test method; while simultaneously, a system was modeled in ANSYS Workbench software, using the finite element method, to subject the specimens to tensile loads under the same parameters of the mechanical test.
