Estimating the term…
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.
A laminated article of manufacture comprising a plurality of layers of fiber-reinforced material, comprising a textile material in the form of a web and thermoset resin, said textile material being from 30 to 70% by weight of said fiber-reinforced material and consisting essentially of synthetic, organic polymeric fiber, at least 30% by weight of said textile material being polyester or polyacrylonitrile fiber and wherein the thermoset resin contains up to 25% by weight of a powder or particulate fluoropolymer, said plurality of layers being stacked on top of one another and having a shape in the form of the article of manufacture.
