Abstract: There is described a fiber-reinforced material composed of a sheetlike textile material and a thermoset resin with a fiber content of from 30 to 70% by weight, at least 30% of the fiber being synthetic fiber. The thermoset resin is preferably a phenolic resin which contains up to 25% by weight of a fluoropolymer. The sheetlike textile material is preferably 100% synthetic fiber, in particular polyacrylonitrile fiber. There are also described a prepeg formed from the textile material and the thermosetting resin and the process for producing these articles and the use of the material for producing construction elements, in particular for hydraulic systems, by application of mechanical shaping processes.
