FIELD: chemistry.
SUBSTANCE: invention relates to composite materials which can be used in aircraft construction. The composite material is made from aramid type fibre reinforcement (bundle) and a composition consisting of a mixture of epoxy resins as a polymer matrix and an aromatic amine as a hardening agent, with the following ratio of components in wt %: epoxy resin UP-610 17.6-24.7, aliphatic epoxy resin DEG-1 3.1-4.4, aromatic amine UP-0638 4.2-6.0, aramid type fibre reinforcement 65-75.
EFFECT: composite material has better elastic and strength properties, particularly Young's modulus of elasticity of 123 GPa and ultimate tensile stress of 2,57 GPa.
