Fiber-reinforced materials are produced by a process in which a heat-stable thermoplastic aromatic polyether A which contains reactive groups, preferably nitrile groups and/or sulfur bridges and/or arylthio or alkylthio groups, if necessary together with a heat-stable thermoplastic polymer B which does not contain any reactive groups, is applied onto reinforcing fibers, the resulting semi-finished product is molded and, in the molding obtained, the plastic matrix is crosslinked so that the glass transition temperature increases and it becomes virtually insoluble.

A fiber-reinforced material containing an effective amount of a heat-stable thermoplastic aromatic polyether which carries reactive sulfur groups, and from 30 to 85% by volume of oriented reinforcing fibers, wherein the plastic matrix is crosslinked via the reactive sulfur groups so that the fiber-reinforced material has a glass transition temperature of greater than 100°C. and is virtually insoluble in low-boiling chlorohydrocarbons.
