Description

Methods for the manufacture of layered cocoa are known. cellular filler, for example, a blade) airborne and propelled intosis, wing, feathers and other publications. isAieiouinx glass fiber tovayuyuchku (skin) and metal honeycomb, based on primekepii glue as a mixture of yush, its prodredstva and pressokanin with pop and terature and increased pressure.

The described method allows to increase the reliability of the connection while increasing the strength and rigidity of the structure. To do this, the glass-cloth laminated cloth impregnated with glue is laid (wrapped) along the E "at the cellular perimeter edge; ln; 1tel, and then, with their temperature and pressure, it is subjected to processing until full polymerization; connected to the most classic honeycomb.

For the manufacture of hollow structures, the example ;: South is a process insert that can be removed at the end of the process /: a field of hydration.

FIG. 1 shows the propeller blade manufactured by the described method; in fig. 2 is a cross section of the structure, which is in the process of testing, with the use of a technotological removable insert.

The blade is formed from a core, made; in the form of met. l. p. com honeycombs / wrapped with layers of impregnated polpmer 1b: M glue of a glass textolite fabric that forms the casing 2. By 01 011-11 wrapping, the spade is enclosed in a mold and, at appropriate temperatures and pressures, is processed to complete : 1sri;:.; Ideas:, -; e; i, as a result of which the etekloketotolitic shell acquires the necessary strength and turns out to be reliable1 0 skrele: i; s with cep; ie4HiiKOM, No. 127911

A technological insert 3 is used to form the hollow construction (Fig. 2), which is initially wrapped with proppant glue with a glass-xftolit fabric forming the inner sheath 4, and then the honeycomb core 5 is wrapped around it with the outer sheath 6. Thereafter, the design is replaced with a suitable thermocline processing and onressovkn in the press-fo). But at the end of the polymer, the glue liner 3 is removed, which results in healing of the emptiness of the structure;

Subject invention

I- A method of making layered structures with honeycomb filler. H, for example, blades for air propellers, wings, onrenp and nrochnyh products having a glass-cloth textolite shell (plating) and metal honeycomb, based on glue as a media: tva It has a temperature and increased pressure, characterized in that, in order to increase the reliability of the joint, at the same time increasing the rigidity and rigidity of the structure, the glass-cloth laminate fabric impregnated with glue is laid ( vayut) but the outer perimeter of the cell for. the filler, and then at the appropriate temperature and pressure, it is subjected to processing until complete polymerization, as a result of which a glass-cloth-textolite shell (skin) is obtained, firmly connected to metal honeycombs.

2. Method but also. 1, characterized in that, in order to manufacture hollow structures, a technological insert is used that can be removed during the polymerization process.
