Arnaldo Carlos Morelli

He holds a degree in Materials Engineering from the Federal University of São Carlos (1979), a master's degree in Materials Science and Engineering from the Federal University of São Carlos (1995) and a PhD in Materials Science and Engineering from the Federal University of São Carlos (2000). He has experience in the area of Materials and Metallurgical Engineering, having worked mainly in the following areas of knowledge: Refractories for the Steel, Metallurgical and Petrochemical industries; technological knowledge of production and manufacturing processes for ceramic slips and deflocculants, special refractory concretes and Portland cement; chemically bonded and ceramic alloy refractories, in addition to other types of refractories for applications in the areas of continuous and indirect casting, gate valves, sintering and reheating furnaces in general, steel ladles and pig iron, torpedo cars and converters; thermomechanical properties of refractory materials; mechanical properties of composite materials and manufacturing processes of composite materials for the aeronautical industry.He is currently a full professor at the Federal Institute of Education, Science and Technology of São Paulo, in the Area of Materials for the Aeronautical Industry, on the Aeronautical Engineering course, having completed an internship in France at the Lycée Saint Exupéry, in the area of Composite Materials for industry aeronautics, obtaining knowledge in the areas of manufacturing, recovery and repair processes of aeronautical structures made of composite materials, consisting of carbon fibers, glass fibers and Kevlar fibers in matrices of epoxy resins, polyester resins and phenolic resins, construction and repairs of structural composites, made up of aluminum honeycombs, cork and cardboard.Three-dimensional composite materials, consisting of glass fiber fabrics, three-dimensionally reinforced with Kevlar fibers, nylon fibers and carbon fibers, obtained by the resin infusion process,Research in the areas of composite materials, consisting of polymer-ceramic, ceramic-ceramic and ceramic-metal.Refractory ceramic composite materials, consisting of cement-free concrete, with carbon nanoparticles and carbon fibers, for applications in small and medium-sized rocket nozzles, to withstand temperatures of up to 1800C, carbon carbide crucibles for casting aluminum parts.Silica aerogel ceramic fibers, obtained by sol-gel technology with silica nanoparticles, for insulation temperatures of up to 1600C.Research is being developed with sol-gel technology in the production of hybrid aerogels obtained by crosslinking via the liquid phase or vapor phase, through epoxy resins and polyurethanes, aiming for applications in large aeronautical and aerospace structures.Thermoacoustic insulation materials in the form of sandwich-type composites containing materials in the shape of central honeycombs covered with composite laminate sheets consisting of ceramic fibers with resins for applications in internal linings of large and small aircraft structures.
