摘要： The invention relates to a method and a device for producing an annular multiaxial laid fabric and to an annular object produced therewith. The object of the invention is therefore to create a method and a device for forming a multiaxial laid fabric for annular structures which has no twisting or displacement of the thread layers. Furthermore, it should no longer be necessary to close a butt join or overlap separately to form a closed ring of the multiaxial laid fabric. This object is achieved in that at least a lower thread layer (2a) and an upper thread layer in the form of an endless thread array or an endless single thread, or in the form of thread-array sections or single-thread sections, are laid around the entire circumference of two mutually spaced ring elements (3) with differing thread orientations, and the first and upper thread layers (2a, 2b) are then fixed to each other at points.

摘要： An impregnation system and a method for impregnating a textile fabric for composite components are described. A matrix 2 can be applied to a textile fabric 1 in such a way that the matrix 2 penetrates it at least partially and/or at least on one side. A first and a second endless belt 1 each designed as a belt loop are provided for the impregnation system. Between the first 4 and the second belt loop 5, the textile fabric 1 can guided on the mutually facing surfaces 6 of the belt loops and can be impregnated there. The deflection rollers 7 are provided in the respective belt loop 4, 5 of the respective endless belts at the deflection areas, with at least one roller being adjustable in the direction of the mutually facing surfaces 6 of the belt loops 4, 5. By adjusting the rollers 8 in the y direction, the wrap angle and thus the pressure exerted on the textile fabric during impregnation is controlled.
