摘要

Widespread demand for reproducible dry preforms for the production of composite parts has promoted new developments in textile techniques. Altin Naehtechnik, a former producer of industrial sewing machines in Germany has developed a system which allows the combination of continuous moving industrial robots with discontinuously operating stitching systems. The developed stitching heads are carried via the manipulator along the seam line of the fixed work piece. The various types which are described allow the application of carbon fiber threads and can be used for shaping of the structures as well as for the reinforcement through the thickness. Patented new stitching techniques which allow the approach to the work piece from only one side or the reinforcement of the structure in the mould are explained. Almost any shape of preform can be produced by stitching, avoiding the use of time consuming braiding procedures. Examples for fixture designs and produced dry preforms are given.
