Technology of composite materials is fast developing and promising direction for solution of operational, economic and ecological tasks of substitution of previous generations’ materials. Measurement of the elastic properties of the composites during their development is necessary to confirm that they meet requirements. The paper shows possibilities of measurement of velocities of longitudinal and shear pulses, which are induced by optoacoustic conversion in metallic composites. The feature of suggested approach is non-contact detection of ultrasound by electromagnetic acoustic transducer.
