Title:
RAPID-CURING COMPOSITION FOR THE PRODUCTION OF SEMI-FINISHED PRODUCTS ENABLING THE PRODUCTION OF COMPOSITE TYPE IV PRESSURE TANKS FOR THE ON-BOARD STORAGE OF HYDROGEN GAS
Document Type and Number:
WIPO Patent Application WO/2023/088977
Kind Code:
A1
Abstract:
The invention relates to a composition (C) comprising (A) 70 to 95 parts by weight of an epoxide resin having a viscosity of between 1 and 150 kPa.s at a temperature of between 20°C and 25°C, and (B) 5 to 30 parts by weight, per 100 parts by weight of resin present in the composition, of a curing agent dispersed in the resin, the curing agent being an ionic liquid containing a phosphonium cation. The invention also relates to a semi-finished product or towpreg, comprising a bundle of fibres (F) and a composition (C). The invention also relates to the use of a composition (C) or of a semi-finished product according to the invention for the production of a hydrogen tank, in particular a type IV pressure tank, made of composite material, for the on-board storage of hydrogen gas.
