The aim of this work was to obtain structural reactive materials from high-energy mixtures. The effect of various additives on the parameters of the burning rate and the ignition temperature was studied. The object of the study was a powder mixture based on nickel and aluminum in a stoichiometric ratio with a particle size of less than 50 microns. Boron and tungsten fibers were used as reinforcing and energy elements. Mixtures of powders were compacted to a relative density of 0.7 and 0.8. Specimens were made in the form of a parallelepiped. The strength of the samples was studied using three-point bending. It was possible to increase the initial strength of the samples by 9 times when reinforced with tungsten fibers.
