Hot-curable compositions which are stable on storage contain, in specified proportions, a) polyglycidyl ether of the formula I <IMAGE> in which X is a group <IMAGE> R is hydrogen or methyl and n is an integer from 2 to 4, b) an epoxy resin having a functionality of 2-2.5, c) a diphenol curing agent, and d) an accelerator. The compositions are particularly suitable for the production of prepregs for fibre-reinforced composite materials or for the preparation of adhesive films. They have a low viscosity even at room temperature and can therefore easily be applied. The cured mouldings are distinguished by a high glass transition temperature and high impact strength. |
