Abstract
The composite materials are born to obtain a good balance between weight, strength and ductility. In addition, the processing systems and new methods of reuse made it more and more convenient. Now we are bringing the extreme use of the composite with the production of advanced ceramic composites Carbon/Carbon and Carbon/SiC. These products have a temperature resistance at about 3000°C and the opposite up to -200°C. It is a monolith that does not deform or melt when subjected to thermal shock as is the case for metals. Furthermore, in addition to being much more hard and non-deformable resistant they are much lighter than steel or titanium. Chevron industries have developed a number of products in Carbon/Carbon with complete proposal of HT items in the world market with the brand name Bluesteel™, Dura™, Ultimate™ and Quantum™. Our company is also sensitive to weight reduction in the cost of manufacture of the components that are the driving forces for the new composite that must be developed by the cost-effective process. In fact, we use a process with Triple Thermal Treatment (exclusive plasma combined named TTT® IPR) that uses the combination of microwave/infrared reducing energy consumption by 85%, CO2 emissions by 87% below the traditional method and with faster processing times 40% (here under one of the operating diagram of a Chemical Reactor CVI/CVD with TTT® methodology).
