PRODUCTION OF COMPOSITE METAL PART WITH INTERNAL REINFORCING FIBRES, BILLET TO THIS END AND METAL PART THUS MADE Russian patent published in 2015 - IPC C22C47/06 C22C47/20 

FIELD: process engineering.

SUBSTANCE: invention relates to production of composite metal part, billet for said part and can be used for production of parts with high resistance to expansion and compression, say, aircraft landing gear components. Billet consisting of metal body or container 10 with support chamber 12, insert 14 with reinforcing fibres shaped to said chamber 12 and arranged therein, metal cover 16 press-fitted in said chamber 12 on insert 14. Billet 20 is placed in processing chamber for isostatic compaction in hot state. Billet cover 16 is rigidly connected with metal body or container 10 by diffusion welding in said processing chamber before isostatic compaction in hot state. Then, billet 20 is machined to get the composite metal part 30.

EFFECT: ruled out gas ingress into chamber 12, higher efficiency of the seal and welding quality.
