High-Performance Fibre-Reinforced Composites Prepared by a Novel Preform Manufacturing Routine
The cost-reduced manufacturing of complex textile preforms suitable for liquid composite moulding of high-performance fibre-reinforced polymer composites is of significant importance for today’s aerospace industry. In this study, modern stitching technologies combined with thermally induced preform stabilisation by incorporation of thermoplastic binder materials are demonstrated to be one of the key approaches towards achieving this challenging goal.
In order to obtain superior overall mechanical composite properties, innovative thermoplastic stitching yarns as well as binder non-woven mats were utilised here to prepare novel preforms for non-crimped carbon fibre-reinforced epoxy composites. The combination of low melting-temperature, matrix-soluble yarns and their corresponding non-woven binder mats is demonstrated to provide an excellent overall performance to the final epoxy composites as well as allowing an enhanced initial stabilisation of the dry preforms by thermo-bonding.
These promising experimental results therefore contribute significantly towards emphasising the general feasibility of using modern textile preforms for the manufacture of advanced composites as well as highlighting the benefits of adopting advanced stitching technologies for high-performance composites suitable for aerospace applications.Lesen Sie die deutsche Zusammenfassung auf Kunststoffe.de
