Possibility of application fibrous additives of a natural origin in an ice matrix as the reinforcing additives is investigated. As a matrix, fresh ice water was used, reinforcing additives — hay fiber 10 mm long and 0.5–1 mm thick and basalt fiber produced by Plant of Basalt Materials LLC (Pokrovsk, Sakha Republic (Yakutia)) with a thickness of 9–12 µm and 40 mm long. The volume content of hay fibers was 10, 20, 30%. The density of chaotic styling of basalt fiber in a single layer was about 3 mm / mm 2 . Magnitude of breaking load was determined experimentally when tested according to three-point bending pattern. It is shown, that introduction fibrous additives a natural origin leads two - to triple increase of ultimate bending strength of fresh ice. During the tests, unreinforced ice samples fractured brittle along the loading force, and reinforced samples showed viscous fracture and an increase in breaking load due to the mechanical adhesion of reinforcing fibers to ice matrix.
