Research output: Chapter in Book/Report/Conference proceedingConference contribution


The increasing usage of CFRP components in mass production industries requires the development of efficient processes based on both existing and new manufacturing methods. The novel splineTEX process, made by superTEX composites GmbH, is related to common bladder inflation moulding techniques and enables a cost-effective production of three-dimensional curved CFRP tubes, but is currently limited to smaller series. Application areas for splineTEX structural elements range from architecture&design, sports equipment to automotive and aerospace industry. In a national-funded project, the splineTEX process is being optimised for high-series production by implementing RTM methods and automating specific sub-processes. To characterize the impregnation behaviour of the braided reinforcements, determination of textile permeability has to be done. Therefore, a new concept has been developed to measure the in-plane permeability of circular, carbon fibre braided sleeves.
