The invention «The method to produce binder based on phenolformaldehyde resol resin for stratified material, binder and stratified material based on binder and reinforcing fiber base (RU 2594014)» refers to polymer composite materials that can be used in manufacture of products designed for aircraft, construction, automobile and household industries. This method is based on component mixing. Resin and fospoliol are taken in dissolvent that is a mix of ethyl alcohol and dimethylformamide. This is the ratio of the components (mass.%): resin - 23,7, dissolvent - 75,3, fospoliol - 1,0. Nanomodifier - mechanically activated diamond - is dispersed into the obtained mixture. The mechanically activated diamond is produced in ball crusher when ration of ball mass and initial detonation nanodiamond is 20:1 respectively and the speed of ball rotation is 900 rotations per minute for 5 minutes. Stratified material based on binder and reinforcing paper fiber is based on aromatic polyamide and possesses finishing layer which composition contents polyamide, ethyl alcohol and water. The binder is applied evenly on the surface of finishing layer, its quantity is equal to the mass of fibers.
