Abstract

The area of multifunctional composites is constantly expanding, since its use allows the design of materials that do not only have the function of mechanical support, but also add thermal, electrical, magnetic, improvements. In addition, it is essential that the laminate obtained promotes a reduction of the mass and volume of the system, thus increasing its efficiency. In this work, buckypapers of carbon nanotubes (BP) will be obtained from the vacuum filtration technique. Subsequently, two types of semipregs (Poly (aryl ether ketone) (PAEK)/Carbon fiber and Polyetherimide (PEI) / carbon fiber will be evaluated and the material with the best characteristics, including impregnation of buckypaper will be used for the processing of multifunctional composites by hot compression molding. After processing, the materials will be subjected to the environmental conditioning of UV radiation, in which the material will be subjected to radiation for 8 hours and condensation for 4 hours. With the conditioned materials, the influence of the BPs on the thermal conductivity, which will be realized by DSC, and the contribution on the viscoelastic properties of the composite will be evaluated, which will be evaluated by DMA. In addition, the influence of the BPs on the interlaminar fracture resistance of the laminates will be studied via DCB and ENF tests. After the mechanical tests, a study will be carried out involving the fractographic evaluation of the laminates in order to verify possible changes in the failure modes due to the incorporation of the BP. Finally, this research will explore the feasibility of using bukypaper of carbon nanotubes in the processing of multifunctional polymer composites with structural applications in the aerospace sector. In this way, the novelty of this proposal is the use of buckypapers to obtain structural composites with aerospace applications, which is a subject rarely explored in Brazil and considering aerospace applications in the world.
