Study of the processes of hot extrusion of composite materials reinforced in the longitudinal direction and alloyed with diamond grains

It has been established that fiber hardening makes it possible to obtain a more effective strength of composite materials in metallic and non-metallic matrix systems. To obtain the required physical and mechanical properties, hardening with discrete fibers or grains is preferable. The dependence of the laws of extrusion on the initial parameters of the fibers and on the extrusion coefficient is revealed on individual samples. The technology for producing a composite material by extrusion has been developed. The internal structure of the diamond-bearing tool at using certain extrusion modes is studied which leads to a high working capacity of the working surface of the tool
