FIBRE PREPREG FOR MAKING WEAR-PROOF POLYMER COMPOSITE MATERIAL (VERSIONS) Russian patent published in 2009 - IPC C08J5/24 D03D1/00 

FIELD: chemistry.

SUBSTANCE: present invention pertains to machine building, and particularly to fibre prepreg, used for making objects for various purposes from wear-proof polymer composite material. The fibre prepreg is made in form of a fibre base from fusible, as well as glass or carbon fibres of infusible threads. The fibre base is made from a complex thread, weaved from fusible and infusible fibre. The fusible fibre in the complex thread is ultrahigh-molecular polyethylene, or polypropylene, or polyethylene caproamide or polyethyelene terephthalate. The infusible fibre in the complex thread is polyoxadiazole fibre and cotton fibre, or polyparaphenylene terephthalamide fibre or polymetaphenylene terephthalamide fibre. The prepreg is made in form of a sheet (fabric), ribbon, linen, non-woven material or cut thread. Part of the fusible fibre in the complex thread can be substituted with powder or granules of fusible material.

EFFECT: design of a fibre prepreg, use of which increases the longevity of different components, made from the prepreg.
