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.

Explanation:
Following are the kinetic theory of gases postulates:
1) Space-volume to molecules ratio is negligible.
2)There is no force of attraction between the molecules at normal temperature and pressure. The force of attraction between the molecules build when the temperature decreases and the pressure increases.
3) There is large space between the molecules resulting in continuous motion.
4) The free movement of molecules results in collision which is perfectly elastic.
5) The molecules have kinetic energy due to random movement. But the average kinetic energy of these molecules differs with temperature.
6) Molecules exert pressure on the walls of the container.
