    Análisis del proceso de ranurado del material compuesto de matriz polimérica con resina epoxi y poliester reforzado con fibra de abacá

    The following research has as an objective to study the behavior that the material composed by the polymeric matrix with epoxy resin and polyester reinforced with abaca fiber has, at the moment to be subject of a grooving process, changing mechanization process parameters such as the cut speed and the advance speed, as well as the kind of tool to use. It is based on the surface response method to design the experiment, obtaining 52 combinations, each with its respective replica, giving a total of 104 grooves with cut-off speed values between 25.13 and 75.4 m/min, and an advance between 0.08 and 0.12 mm/rev, it is also applied the use of two different milling tools; the first tool 103-S (Super Acabado “Plexiglas”) and the second 107-M (Diamond serrate with front cut), the obtained results were entrance delamination factors, exiting factors and rugosity, allowing to know the superficial quality of the mixture. At the moment to develop a simultaneous optimization of the parameters used in the machining with a combination of a 85.81 m/min cut speed, advance of 0.12828 mm/rev, kind of tool 103-S, and a polyester resin matrix, entrance and exiting delamination factors are obtained similar to 1.0281 and 1.0707 respectively, and a rugosity of 2.3460μm; such values could be the best surface quality for this mixture. To complement the research, UV degradation essays were elaborated with 50, 100 and 150 exposure hours, concluding as the maximum effort traction capacity for the epoxi resin which is in the 100 hours and the polyester one to the 50 hours.
