Estudo da utilização do nitinol em materiais compósitos

Abstract

The opportunity to unite two or more different materials in order to achieve structures capable of adapting to the operational context has guided the development of intelligent composites with functional properties capable of controlling shape, rigidity and vibration. In this scenario, hybrid composites reinforced with shape memory are excellent alternatives, since the wires of these alloys have the ability to modify the stiffness and/or elasticity of a composite through external stimuli such as thermo-mechanical, electrical and magnetic. However, in addition to the difficulty related to controlling the behavior of shape memory alloys, hybrid composites also present the intrinsic complexity of manufacturing and characterizing this class of materials. Thus, this work addresses hybrid composites with nitinol reinforcement and aims to present a study on the effect of shape memory, the development and manufacture of these structures in applications of smart materials, expanding national scientific research on the subject.
