FIELD: engines and pumps.
SUBSTANCE: proposed method comprises cutting out circular and lengthwise work pieces from glass fabric impregnated with binding agent, and streaks of BK-3-grade adhesive tape to be processed by solvents, for example, acetone. Inner and outer layers are composed of annular work pieces on female die corresponding to plug shape. Flange inner and extra annular layers are composed of lengthwise work pieces. At least, one adhesive tape streak is laid between fiber glass lengthwise layers. Then, produced multilayer pack is subjected to hot moulding. In moulding, said pack is heated at pressure to 115-125°C to be maintained for an hour. Then heating is performed to 155-165°C to be maintained for 1.5 h. Then heating is performed to 175-165°C to be maintained for 2.5 h. Thereafter, said pack is cooled to 50°C and pressure is released.
EFFECT: higher quality.
