Composites (such as carbon-fiber-reinforced polymers) have the properties of both metals and plastics. true or false

The given statement is true.  

The CFRP or carbon fiber reinforced polymer refers to an extremely light and strong fiber-reinforced plastics that comprises carbon fibers. The CFRPs are generally used in aerospace, automotive, the superstructure of ships, sports equipment, civil engineering, and an enhancing number of technical and consumer applications.  

The CFRPs are the composite substances that exhibit the properties of both plastics and metals. The CFRPs comprises two components, that is, a reinforcement and a matrix. Carbon fibers act as a reinforcement that offers the strength, and the matrix is generally a polymer resin like epoxy, which is used to hold the reinforcements together.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
