    In this work, an experimental investigation of a composite material for the determination of the mechanical properties made up of polyester resin reinforced with fiberglass and steel mesh was carried out. In this composite material, the steel mesh reinforcement has 2 different types such as: galvanized steel mesh and stainless steel mesh, the number of fiberglass layers was varied, the preparation of the test pieces was carried out by compression stratification with a mold Constructed of A36 steel material. In this research the purpose is to find the best configuration that provides high mechanical properties, the specimens are tested and manufactured according to ASTM standards, for tensile testing the ASTM D3039 standard was implemented, in the bending tests the ASTM D7264 standard and test to impact according to ASTM D5628. After being tested the specimens, tabulated and collected the data. The configuration that presents the best results is that of 2 layers of fiberglass, 1 layer of stainless steel mesh cured at 25 degrees centigrade in the environment, made with compression stratification, resulting in a maximum tensile stress of 64.01 (MPa), maximum bending stress of 145.85 (MPa) and mean failure energy of 0,910 (J).

    Diseño y construcción de máquina rotativa de corte longitudinal de planchas de acero galvanizado de 1 mm de espesor en la empresa Carrocerías “IBIMCO S.A.”
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Carrera de Ingeniería Mecánica, 2017) Iza Carrillo, Edgar Vinicio; Guamanquispe Toasa, Jorge Patricio
    For the execution of the project the shear cutting process was investigated by means of an unconventional system which allows longitudinal cuts of dimensions larger than those established for a standard metal plate, from which different design alternatives were determined. Of these, the circular blade cutting system was selected as the main mechanism, which consists of a combined transmission of chains, catars, pulleys and belts, as well as a power reducer and a three-phase electric engine. The parameters specific to parts and components were designed taking into account the actual conditions on which the machine will work in addition to safety factors recommended by entities such as ASTM-HANDBOOK. Once the design and construction were carried out, the functional tests were carried out where it was verified that with the implementation of the machine clean cuts can be made with minimum tolerances, reducing the 40% of time during the cutting process in relation to the conventional process used in the company.
