METHOD AND DEVICE FOR PRODUCTION OF COMPOSITE ARTICLE Russian patent published in 2015 - IPC B29C51/02 

FIELD: process engineering.

SUBSTANCE: invention relates to production of composite article. In compliance with this process, intermediate article is extruded fibrous stock comprises fibre and polymer-based material. Then, at least one forming tool is used to make form the composite article. At extrusion, intermediate article cross-section profile is formed with the help of at least one extrusion tool. After application of extrusion tool the temperature of intermediate article is adjusted so that various parts of intermediate article cross-section profile accommodate different temperature zones in compliance with preset target temperature ranges. Intermediate article temperature is adjusted at different parts of cross-section profile in the range of 50-250°C. Composite article is formed from intermediate article with the help of forming tool that makes the compaction.

EFFECT: production of composite article in single process step.
