    摘要： Fiber-reinforced materials are produced by a process in which a heat-stable thermoplastic aromatic polyether A containing reactive groups, preferably nitrile groups and/or sulfur bridges and/or arylthio or alkylthio groups, if required 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 shaped, and the plastic matrix in the molding obtained is crosslinked so that there is virturally no increase in its glass transition temperature although the amount of soluble material is decreased to less than 60%, determined by extraction in boiling dichloromethane for one hour.
