Elaboração de material didático-instrucional de processos de fabricação de material compósito de matriz polimérica utilizado na indústria aeronáutica

Abstract

The use of composite materials are ever more common in the industrial sector, especially in the construction of several structures of modern aircrafts. The high demand for materials with elevated strength and stiffness and reduced specific mass, drives the search for new combinations between matrix and reinforcement elements, aiming to build a composite that presents not only specific and inherent characteristics for each type of application, but also superior mechanical properties when compared with other conventional materials. The development and application of composite material are wide, reaching several sectors, which makes it necessary to know their characteristics and generalities. Considering the how important is the use of composite materials in aircrafts, this work aims to compile information about polymer matrix composites, its types and main manufacturing processes, as well as applications in the international aeronautical industry. The fundamental purpose of this work is to compose a didactic-instructional material for students, especially Aeronautical Engineering graduates, with information originated from researches and current applications, mainly because the national aeronautical industry is modest when it comes to applications of composite materials in structural components. We believe that the applications sample collected will be very useful to, not only consolidate the learning and teaching capabilities of the referred context, but to instigate in the student the interest for research. It is a “one way street” because certainly the use of composite material in aircrafts structural components will grow over the years, allowing gains in lightness and geometric innovations, with more daring and efficient aerodynamic shapes, when compared with conventional materials.
