METHOD OF MOULDING ARTICLES FROM COMPOSITE MATERIALS BY AIR FORMING USING INFLATABLE CHAMBER MADE FROM LIQUID RUBBER AS PUNCHEON Russian patent published in 2020 - IPC B29C43/10 B32B27/00 B32B17/00 

FIELD: chemistry.

SUBSTANCE: invention relates to methods of forming articles from composite materials, in particular, to methods of compaction of composite material, and can be used for production of structures in aircraft and space equipment. Method of pressing articles from composite materials, including using a sealing element from rubber to create moulding pressure, supplying pressure, hardening of article and its removal from process equipment (matrix), is characterized by that in process of pressing sealing element is covered with tooling - matrix cavity, pressure is created on the rubber element, which in the process of pressure supply is partially filled with the recess of the tooling tool - matrix, sealing the material and creating moulding pressure when it is cured, it differs from known designs in that puncheon is made up of sealing element with its edges locked by lid. At that, at least, compressed gas supply branch pipe is fitted inside said cover to inflate said sealing element to press preset-shape material thereon.

EFFECT: technical result of the invention is the ability to manufacture products having a complex geometric shape, and composite products of complex shape of fabric materials, such as glass fabric, industrial fabric, non-woven polymers.
