FIELD: chemical industry. SUBSTANCE: in manufacturing a composite material, carbamidoformaldehyde resin (CFR) is added to the compound prior to the addition of a coagulant. CFR having a gelatinization time of 140-260 s is used in the form of a dispersion which represents a product of suspension polycondensation of carbamide and formaldehyde in the presence of a protective colloid such as a copolymer of butylacrylate, butylmethacrylate and methacrylic acid, their weight ratio being 1:(0.41-0.45):(0.15-0.19) and the carbamide to protective colloid ratio being 1:(0.05-0.12). EFFECT: improved properties of the composite material. 1 tbl
