Shock wave consolidation of materials

摘要

A composite structure comprises several layers of various materials which are to be united by welding and simultaneously consolidated. The method resides in that the densities and moduli of elasticity of the various layers are adapted by composition, shape, state and temperature in such a way that the velocity of sound is considerably modified upon penetration of the composite structure. A shock wave is applied to one or both sides. This shock wave breaks down into harmonic vibrations that can sum up, concentration of energy resulting on the respective interfaces, ensuring the union within and between the layers.
