摘要：
Results of theoretical and experimental studies of the nondestructive testing of the strength properties of polymer composite materials (fiberglass) and articles produced thereof (cylindrical shells) are considered. Most attention has been paid to the ultrasonic propagation-time and acousticemission methods as well as an ultrasonic method based on measuring the velocities of longitudinal and transverse elastic waves in the tangential and axial directions of a cylindrical shell. Analytical and correlation equations have been derived that establish connection between destructive and nondestructive testing.
