Abstract

In stamp forming processes full-clamping systems are usually used for material infeed of textile reinforcement semi-finished products. This can result in draping errors in resulting preforms. Hence, the optical and mechanical properties of such fibre composite components are reduced. Other strategies for feeding the reinforcing layers during forming and simultaneously improving the draping quality are usually only designed for certain blanks. Such approaches cannot be automated or are customised solutions. The aim of this dissertation is the development of a flexible process for the automated and efficient production of high-quality preforms with complex shapes. The approach used to achieve this goal is the development of an innovative textile material infeeding system. A detachable textile joint enables the individual reinforcing layers to slide off during the forming process under a defined retention force. The textile material infeed allows the increase of preform quality with a near-net shape, geometry-flexible and resource efficient material infeed and thus enables a low cost, high quality solution.
