METHOD OF MAKING ARTICLES FROM POLYTETRAFLUOROETHYLENE BASED COMPOSITE MATERIALS Russian patent published in 2016 - IPC C08J5/00 B29C43/56 

FIELD: materials science.

SUBSTANCE: invention relates to materials science, particularly to polytetrafluoroethylene based polymer composite materials production methods, and can be used for production of metal-polymer friction units workpieces and parts. Disclosed is method of making articles from polytetrafluoroethylene based polymer composite materials, whereby performing components mixing with polytetrafluoroethylene, workpieces cold pressing and following sintering, whereby before workpiece sintering, without extracting from mold is subjected to preliminary compression pressure within 0.2-0.5 MPa, pressed workpieces sintering is carried out directly in mold, at temperature of 355-365 °C.

EFFECT: improving sintered composite material mechanical and tribotechnical properties characteristics, as well as simplification and reducing labor intensiveness of tooling manufacturing and production of articles from polymer composite materials.
