Abstract

Preforming is required for complex shaped profiles manufactured in liquid composite moulding (LCM) processes. The stacking is made of dry fiber fabrics, which are infiltrated in a later process step. The complete stacking is called preform. The fixing of the textile layers can be realised through stitching or binder technology. The main disadvantage is the immense rate of manual work within the preform process. In consequence, the manufacturing is costly in terms of time and high effort for quality control. Automated preforming can reduce the costs by increasing the output and production rate while minimising waste. Preform profiles with variable outlines and non-extrudable sections are of particular interest for the aviation and automotive industry. The DLR Institute of Composite Structures and Adaptive Systems has developed an innovative device to overcome the previous limitations and to fulfil the industrial demands.
