Abstract
The analysis of reinforced polymers is one of the most important sources of information for materials properties designers. In this regard, due to their intrinsic properties, the fabrics play an essential role when they are used as reinforcement elements. The composites properties can be designed by alternating various types of fabrics, by modifying the orientation of every reinforcement layer, by modifying the matrix properties or by choosing the matrix. This study regards the tensile behavior of four fabric reinforced composites with four different epoxy resins as matrix. All the materials have the same reinforcement structure but the matrix is, in each case, another epoxy resin and more two classes of materials had been studied one is containing the natural polymerized matrix materials and the other one the materials that had been thermally treated according to technical sheet of each polymer. The tests were done one year after the materials formation.

The analysis of reinforced polymers is one of the most important sources of information for materials properties designers
New materials design will always be in development for the industry of aeronautics, automotive, shipbuilding, military and aerospace
Because during the research carried out over a long period of time it was determined that the polymeric composites reinforced with fabrics and epoxy resins showed very good mechanical results [2,3,4,5], this paper aims to analyses the behavior of the composite materials reinforced with carbon fibers [6], aramid fibers, glass fibers [7], and homogeneous epoxy matrix
Summary
The analysis of reinforced polymers is one of the most important sources of information for materials properties designers. The increasingly widespread use of heterogeneous materials, obtained by macroscopically combining two or more homogeneous materials, justifies the interest in finding the most suitable combinations to satisfy certain requirements, as well as in characterizing the behavior of the resulting composite materials [1]. By designing such materials, the combinations of constituents that can achieve the physical and mechanical characteristics necessary for a certain use can be chosen and have, under given operating conditions, a predetermined lifetime. Glass fabrics have high corrosion resistance, good mechanical properties, dielectric properties, lower impact energy absorption capacity compared to aramid fabric and low cost [7, 20]
