Carbon fibres can be affected by strong oxydizing agents. Some of the key factors are: Type of carbon fiber and resin Fiber to resin ratio (fiber amount, fiber volume) Thus the attractive properties of carbon are combined with the high strength, versatility and toughness of composites. 4- Carbon fiber is Electrically Conductive. Carbon Fiber Composite is also referred to as Carbon-Carbon Composite, CFC, or Carbon Reinforced Matrix Composite. In my January 2019 column, I discussed methods to determine whether properties obtained from mechanical testing of composites are correct — or even reasonable.One of the methods focused on comparing test results in question to those available in public databases for similar composite materials. The properties of Carbon-Carbon (C-C) composites are Main raw materials of carbon composites are polymeric resins and carbon fibers.
