Process for obtaining oxidised poliacrilonitrila felt and felt of carbon fibres, from poliacrilonitrila felts.Applied in the manufacturing of composite carbon reinforced with carbon fibers (crfc), with hu00ecbrido configurations and sanduu00ecche ".Patent of invention of a process for obtaining felt poliacrilonitrila oxidized (PANOx) and felt of carbon fibres from felt poliacrilonitrila (Pan).The achievement of PANOx starts with the process of oxidative stabilization of felt of pan at temperatures between 100 and 200.This material is subsequently treated at high temperatures (800 - 2500u00b0c), with elimination of elements not carbonic, for obtaining the carbon fibre felt.The carbon fiber felts are used together with carbon fiber fabrics, such as reinforcement in composites manufacturing crfc, in two types of configurations: hybrid and sandwich.The phenolic resin of the type resol material used as matrix precursor of carbon.
