COMPOSITION OF RESIN WITH CHAIN MECHANISM OF HARDENING AND COMPOSITE MATERIAL RE-ENFORCED WITH FIBRES Russian patent published in 2014 - IPC C08G59/24 C08G59/40 C08L63/00 C08J5/04 

FIELD: chemistry.

SUBSTANCE: claimed invention relates to composition of resin with chain mechanism of hardening for composite material re-enforced with fibres. Described are versions of composition of resin with chain mechanism of hardening for obtaining composite material re-enforced with fibres, which contains: alicyclic epoxide compound (A), which contains two cyclohexene oxides in a molecule; and modified epoxy resin (B) of bisphenol type A, represented by formula (1) given below, where in modified epoxy resin (B) of bisphenol type A each R¹ represents -CH(CH₃)-, and R² represents oxyalkylene group, and content of alicyclic epoxy compound (A) constitutes from 25 to 90 wt %, where total amount of component (A) and component (B) is taken as 100 wt %: [Chemical compound 1]

in formula (1) n represents integer number, which equals 1 or more. Also described is re-enforced with fibres composite material, obtained by formation of said composition of resin with chain mechanism of hardening by method of injection transfer molding of polymer.

EFFECT: reduction of energy consumption and reduction of duration of resin hardening process in combination with good mechanical strength of obtained hardened product.
