FIELD: technological processes.
SUBSTANCE: invention relates to method of forming articles of composite material. Technical result is achieved by method of forming articles of composite material, which involves lining of fibrous material, impregnated with binder, in recess of production equipment and use of sealing elements of thermally expanding rubber to create molding pressure, package, heating, supply of pressure, cooling of hardened product and its extraction from tooling fixture. Wherein volume of tooling cavities is equal to or greater than volume of non-compacted fibrous material, impregnated with binder, forming article. Sealing element is made of strip-like uncured thermally expanded rubber covering recess of tooling. Wherein pressure is transmitted to rubber element via stiff saddle overlapping strip of uncured rubber, which partially fills tooling cavity during heating and pressure supply via saddle, thus sealing fibrous material, impregnated with binder and creating molding pressure during curing.
EFFECT: technical result is reduced labor input, power consumption and shorter production cycle of making article.
