building materials. SUBSTANCE: invention relates to epoxy resin-base building materials and can be used for protection of building constructions and technological capacities from the corrosion. The composite comprises epoxy diane resin ED-16, polyethylenepolyamine, calcium fluoride, polyethyleneterephthalate fiber of length 20 mm and diameter 0.5-1.0 mm and polytrifluorochloroethylene 12F. The combination of components taken in the definite ratio provides the enhanced impact resistance and tensile strength limit value. The impact resistance of articles is 690-1120 J/cm3, tensile strength limit value is 91-100 MPa, mean density value 2180-2200 kg/m3. EFFECT: improved quality and indices of composite. 2 tbl, 3 ex
