The possibilities of increasing the performance of shaped charges by using lens assemblies made of high-modulus ceramics are considered. In this case, an increase in the loading parameters of a shaped-charge liner can be achieved if the detonation wave enveloping the lens propagates in a pre-compressed but unreacted explosive. Pre-compression of an explosive charge without detonation initiation can be achieved by its shock desensitization with the advanced wave transmitted through the ceramic lens. Numerical simulation of detonation wave propagation in a shaped charge with different lens assemblies have shown the potential for using composite lenses in which the inner part adjacent to the axis of symmetry is made of high-modulus ceramics and the outer part is made of an ordinary inert material.
