METHOD OF MANUFACTURE OF THE LARGE-DIMENSION THICK-WALLED POLYMERIC COMPOSITE DETAILS Russian patent published in 2007 - IPC B29C70/40 C08J5/24 B29C43/02 

FIELD: electric power engineering; methods of production of the large-dimension thick-walled polymeric composite details.

SUBSTANCE: the invention is pertaining to the method of production of the large-dimension thick-walled polymeric composite details for the electric power engineering, power engineering, transport vehicles. The method of production of the large-dimension thick-walled polymeric composite details provides that from prepreg manufacture the billet of the detail with the oriented reinforcing prepreg fibers with set increased content of the volatile substances in the binding agent. Conduct polymerization of the billet in the non-sealed mold without the external pressure with formation of the open microporous structure, conduct the thermal stabilization, impregnate the microporous structure with the impregnating composition. Conduct polymerization of the impregnating composition and exercise the thermal stabilization of the finished composite detail. The method ensures production of the finished composite detail with the dimensions not dependent on the temperature variations.

EFFECT: the invention ensures production of the finished composite detail with the dimensions not dependent on the temperature variations.
