INFLUENCE OF BORON STEEL/ALUMINIUM HYBRID COMPOSITE STRUCTURE ON THE ENERGY-DISSIPATION THEREIN/

The technological conditions for making polyreinforced composites by h ot pressing stacks consisting of boron/aluminium monolayers and knitte d nets of stainless steel have been studied. Improvement of mechanical properties, and especially behaviour under cyclic loading, was achiev ed as a result of introducing additional loop elements of thin steel w ires into the macrostructure of the composite. It was found that the a rrangement of net layers, the number of wires in a bundle and the stee l content considerably affected the cyclic strength and energy dissipa tion factor.
