Composite materials used in the aerospace industry must meet severe requirements such as dimensional stability, high stiffness and high temperature resistance. Fire resistance and ablative composites are used in nozzle turbine construction and other components of rockets and airplane engines, exposed to very high temperatures. Phenolic resin/Carbon fiber reinforced composites are indicated for these applications due to its high mechanical and thermal performance. When exposed to flame and high temperatures, these materials form a carbonaceous layer called ?char? that radiates heat and acts as an excellent insulating element that protects the bulk material of the components. In turn, to achieve the necessary standards of mechanical properties, it is essential to ensure a minimum content of bubbles in the material. The best technique for this is the processing by autoclave, that uses prepregs as raw materials for placing resin and fibers in the necessary amount in the mold.The aim of this work is to obtain and to characterize phenolic resin/carbon fiber- prepregs and its composites, which can be used in the aerospace industry. Nanoclays (bentonites) were added to phenolic resin in order to evaluate their effect on the performance of the material. The fire performance of the composite materials obtained was characterized in a cone calorimeter
