FIELD: manufacture of fibre- reinforced products: pipes, vessels, filter casings, etc. SUBSTANCE: multilayer casing has several layers of mix of binder and fibrous filler taken in various relations. Internal layer uses carbon fabric, and external layer - glass- fibre filler, and an intermediate layer. internal layer is formed by application of layers of carbon fabric impregnated with phenol- formaldehyde binder, intermediate layer is made of thermoplastic polymer, and external layer contains glass fibre impregnated with diana type epoxy resin with relation of layer thicknesses within 1:1: (1-45) to 6:6:(10-45) mm; in addition, casing is furnished with protective layers of thermoplastic polymers, temperature control, heat-insulation and electric-insulation layers imparting new service properties to the casing. EFFECT: enhanced strength. 4 cl, 1 dwg , 1 tbl
