Fiber-reinforced material and production and use thereof

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 prepreg 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.

An optical waveguide having a core-sheath structure whose core comprises a terpolymer based on vinylidene fluoride, tetrafluoroethylene and hexafluoropropylene, is suitable for transmission paths of ca. 10 to ca. 100 m and can also be used at a temperature of above 100.degree. C. without significant reduction of the transmission path.

Optical waveguide

An optical waveguide having a core/sheath structure whose sheath comprises a polymer which is based on vinylidene fluoride and at least one other vinyl monomer containing fluorine and has been modified and crosslinked with a trisalkoxyvinylsilane, is suitable for transmission paths of ca. 10 to 100 m and can also be used at a temperature above 100.degree. C. without any significant reduction in the transmission path.
