Comportamento Termoelástico de Vigas SMAHC sob Flexão em duas Temperaturas

Abstract: RESUMONeste trabalho, foi desenvolvido e caracterizado um compósito híbrido com memória de forma (SMAHC) por meio de uma análise teórico-experimental, no regime elástico, envolvendo a fabricação de vigas laminadas. A viga híbrida foi confeccionada em matriz de epóxi reforçada com fios de SMA e mantas de fibras picadas de vidro-E, com e sem bolsa de vácuo, de cura a frio e quente. A viga possui duas camadas de fios, com e sem roving, afastadas simetricamente o máximo possível do plano médio. Também foram produz… Show more

“…The bending modulus of composite cylindrical beams with Ni-Ti bar, showed increases of 18% to 31% that are associated to the effects of the phase change of Ni-Ti wire, from martensite to austenite, induced under conditions of temperature increase in the composite, from 21° C to 56° C. This effect gave the composite the adaptive character and can be used in environments where it is required and under two preferential orientations of 0° and 180° degrees with respect to the axis of application of the load [14].…”

“…One of the most important parameters in the research on composites is the manufacturing methods, so important aspects such as the repeatability of composite characteristics are guaranteed [13], [14]. With regard to the manual winding device, the manufacturing time and the geometric arrangement of the fibers to be wound in the process are the major drawbacks.…”
