Diseño y construcción de un prototipo de máquina de pultrusion y estudio experimental de las variables para la obtención de perfiles “O” de material compuesto con matriz termoestable

Abstract

The work presents a design and construction of a prototype pultrusion machine, which is a process to obtain "O" profiles based on composite materials by means of FRP Fiber reinforced plastic, for the design Was developed by the concurrent engineering, establishing technical specifications, according to the needs of the client, and later a functional analysis was done according to the prototype modules and resulting in an optimum design, which finally was reflected in the construction of the same. Once the machine was developed, an experimental study of the variables of the pultrusion process was established. This was done according to the tests performed. The main parameters were the concentration of the mixture (resin), mold heat zones and The speed of the pullers, with which in the end it was possible to obtain the ideal parameters with which an optimum profile was obtained taking into account that the profile has necessary physical characteristics, that is to say, that it has its desired shape and thickness; It should be noted that the main materials used were the polyester isophthalic resin, catalyst, accelerator, roving thread among others. Subsequently, the material was characterized by the tests developed in the LANUM of the EPN, the tests carried out were tensile and flexion to three points, achieving acceptable values within the characteristics of the machine.
