The results of experimental studies of the mechanical characteristics of carbon fibers (CFRPs) before and after their exposure at seawater are presented. The choice of seawater as an operation medium is due to the fact that this carbon fiber is intended for the manufacture of power elements of a manned underwater vehicle. Carbon fibers were made using vacuum infusion technology based on an epoxy binder, and biaxial carbon fabric was used as a reinforcing material. The prepared samples were kept in seawater for 384 h, which made it possible to estimate the amount of water absorption, as well as the change in mechanical characteristics after exposure to seawater. It has been established that the strength of CFRPs does not change during interlayer shear, decreases by 14% during bending, and the value of the elastic modulus, after exposure to seawater, decreases by 17%.
