FIELD: production of aviation and ship component structures. SUBSTANCE: method of production of multilayer panel from composite material includes placing of prepreg on the surface of mold, laying of drainage member and airtight vacuum bag, giving rise to vacuum in the hollow which is confined by the mold surface and vacuum bag, holding of multilayer panel with rarefaction under vacuum bag of 0.04-0.01 MPa, at least, 24 h at the temperature of 15-30 C, subsequent molding with heating of multilayer panel up to the temperature of setting of polymer binder. In course of holding, it is additionally suggested to communicate periodically 1-2 times at and hour the hollow under vacuum bag for several minutes with atmosphere repeatedly give rise to vacuum in the hollow under vacuum bag, and to continue holding. EFFECT: higher quality of multilayer panel from composite material. 3 cl, 1 tbl |
