Abstract
Carbon is ubiquitous in every activity of modern life. In various allotrope forms, graphite and diamond are the most well known since ancient times of humanity. Currently, carbon fibers and nano-structured carbons plays an important role in many engineering systems, covering areas from energy to medicine, due to their excellent specific properties. The various ways to obtain solid carbon materials make them versatile and the aeronautical/space areas are the ones that most benefit from this virtue. Multidisciplinary processes and the variety of raw materials allows to obtain amorphous and crystalline carbon morphologies which results in wide industrial uses. Steel and aluminum would not exist without Carbon. The pursuit of lightweight materials in aerospace area, looking for structural optimization, lower maintenance costs and energy savings, resulted in large-scale use of composites. The search for the unknown outside the ship Earth, resulted in the development of structures that can withstand the extreme rigors of operational service and design requirements for those environments. For non-oxidizing atmospheres Carbon materials are unbeatable, keeping properties at temperatures up to 3000 oC. For oxidizing environments synergy with conventional ceramic materials, particularly silicon carbide, is necessary due to the instability of Carbon above 500 oC. In this context, the presentation addresses the processing of Carbon/SiC materials and the resulted properties.
