Phosphonates are of great interest, because they are able to increase the glass transition temperature of cured resins by crosslinking in a post curing step. RTM6®, which is commercially available and used by the Aviation Industries, was selected as a premixed epoxy system. The influence on the glass transition temperature was investigated.enconference paper
