Abstract: An apparatus for impregnating fiber structures with a matrix material includes a lower part having a bath for receiving the matrix material and a draining unit. The draining unit includes a wiper having a wiping edge, over which the impregnated fiber structure is guided during operation, and a surface inclined in the direction of the bath, by which matrix material draining from the fiber structure can return into the bath. The draining unit includes a cover on which a deflection unit, by which the fiber structure is pressed into the bath when the cover is mounted, is mounted. When the cover is mounted, a gap is formed between the cover and the lower part on the sides by which the fiber structure is guided into the apparatus and emerges from the apparatus. A method for impregnating fiber structures with a matrix material is also disclosed.

Abstract: Provided herein is a process for producing fiber composite materials which includes mixing an isocyanate component A and a polyol component B to afford a reaction mixture, impregnating fibers with the reaction mixture and the curing the impregnated fibers, wherein the polyol component B includes the alkoxylation product of a mixture of fat-based alcohol (i) and at least one OH-functional compound having aliphatically bonded OH groups and an OH functionality of 2 to 4 which is not a fat-based alcohol (ii). The present compound further relates to a fiber composite material obtainable by such a process and using the fiber composite material as a mast.
