  • Patent number: 10400365
    Abstract: A two-dimensional fabric (20) used to produce a three-dimensional composite part has a binding system (21) with binding warp threads (23) and/or binding weft threads (24) and a reinforcing system (22) with reinforcing weft threads (25) and/or reinforcing warp threads (26). At least some of the inserted reinforcing threads (25) are shortened reinforcing weft threads (25a) and/or shortened reinforcing warp threads (26a). Their thread length (L) is less than that of the binding weft threads (24) or the binding warp threads (23). The shortened reinforcing thread's (25a), (26a) free ends are located in a respective thread end position (30) or (31). The respective thread length (L) and the respective thread end positions (30), (31) of a shortened reinforcing thread (25a), (26a) in the two-dimensional fabric (20) are predetermined based on the three-dimensional shape of the composite part to be produced to reduce cutting waste when producing preforms and cutting effort.

  • Patent number: 9572668
    Abstract: The invention relates to an implant and a set for producing an implant and their uses. Furthermore, the invention describes a method of making an implant as per the invention. An implant for producing bone implants with improved mechanical characteristics, especially with adjustable mechanical characteristics, is provided via the invention. The implant as per the invention made up of a fiber composite material contains resorbable mineral bone cement as the matrix material, to which reinforcing, long metal fibers and/or endless metallic fibers with an aspect ratio of at least 100:1 are added in the form of at least one fiber structure that provides a framework and that preforms the contour of the implant.
