METHOD OF PRODUCING ONE- OR MULTI-LAYER FIBROUS PRODUCT, FIXING THREAD AND BEARING LAYER Russian patent published in 2009 - IPC B29C70/48 B29C70/04 D04H3/04 

FIELD: process engineering.

SUBSTANCE: invention relates to production of production of one- or multi-layer products in TFP-process from fibrous strands oriented along load direction. Proposed method comprises laying fibrous strands on bearing layer and fixing them by fixing thread to make fibrous workpiece. Note that aforesaid fixing thread and/or bearing layer is made from water soluble material, and fibrous workpiece features any required thickness of material. After TFP-process, one fibrous workpiece is placed into fixing device to fix fibrous workpiece strands. To remove at least one fixing thread and/or at least one bearing layer, water is forced through fixing device acting as a solvent. Note also that water is forced through a closed-loop circuit. After removal of fixing thread, workpiece is dried in fixing device. To produce final composite component, workpiece is impregnated by epoxy resin in fixing device in compliance with RTM-process.

EFFECT: ruling out negative effects brought about by fixing thread.
