A PROCESS FOR MANUFACTURING A FIBER REINFORCED EPOXY COMPOSITE ARTICLE, THE COMPOSITE ARTICLES OBTAINED AND THE USE THEREOF

摘要

A process for the preparation of a fiber reinforced composite article comprising the steps of: a) providing a fibre preform in a mold, b) injecting a multiple component thermosetting resin composition into the mold, wherein the resin composition comprises (b1) a liquid epoxy resin, (b2) a curing agent comprising 1,3-bis (aminomethyl)cyclohexane, and (b3) an accelerator comprising at least one compound selected from the group sulfonic acid and imidazolium salt of a sulfonic acid, c) allowing the resin to impregnate the fiber preform, d) curing the resin impregnated preform, e) demolding the cured composite part, facilitates manufacturing of composite articles with reduced cycle times, said composite articles exhibit excellent mechanical properties, especially elongation and fracture toughness, and can be used for the construction of mass transportation vehicles, in particular in automotive and aerospace industry.
