Determination of the elastic constants of some composites by using ultrasonic velocity measurements
An ultrasonic immersion technique was used to determine the velocity and amplitude of sound waves in composite materials. The materials under study were E-glass/IPN, E-glass/PET, Kevlar 29/IPN, Dyneema/PE and Dyneema/Kraton. The velocity and amplitude of longitudinal and transverse sound waves at the frequency of 1 MHz were measured in three planes of symmetry at several angles of incidence. The complex stiffness matrix for the composites was calculated.
