发明名称 METHOD FOR MANUFACTURING A HOLLOW FIBER COMPOSITE COMPONENT AND INTERMEDIATE PRODUCTS FOR THE MANUFACTURE
摘要 An intermediate product for the manufacture of a hollow fiber-composite component having a shape and dimensions, includes a three-dimensional, hollow preform of reinforcing fiber material corresponding to the shape and the dimensions with a three-dimensional reinforcing fiber structure which is formed from at least one planar, single- or multi-layer blank of two-dimensional, web-like reinforcing fiber material matching the dimensions, and a closable total cross-sectional profile with at least two hollow chambers located adjacent to each other and separated from each other by a rib-like partition. The partition is formed by an overlap region of the at least one blank which is stitched in two dimensions by a compacting seam which fixes the shape and dimensions of the rib-like partition as well as its position relative to adjacent regions of the blank and prefixes, precompacts and reinforces the reinforcing fiber material in the region of the partition. In addition, a method for the manufacture of a hollow fiber-composite component by means of such an intermediate product.
