Conclusions

  1. 1.

    In the manufacture of VKA-1 composite material the diffusion welding of the semifinished product is accompanied by the formation at the fiber/matrix interfaces of the AlB2 phase in the form of spherical inclusions at sites of Al2O3 film disintegration on the matrix foils.

  2. 2.

    To each diffusion welding temperature there corresponds a certain period of time during which no AlB2 phase is formed at the fiber/matrix interfaces.

  3. 3.

    A method of assessing the defectiveness of the surfaces of reinforcing fibers is described, which can be effectively employed for studying the reaction in the CM, particularly its early stages.
