Objective
The overall aim of ITOOL is to increase the usage of textile preforming for composites in Aeronautics applications. It is well-known from related projects that preforming offers a potential cost saving of 20-30% in materials and processing compared with p repreg technology. But a still missing prerequisite for taking advantage of this potential are adequate design and analysis methods and especially validated simulation tools. The technical approach of the project covers this aspect by development of an int egrated solution, simulating the manufacturing and processing chain as well as the loading stage to get reliable results also for 3d fibre architectures. Focus is laid on braiding, weaving and stitching technologies including also Non Crimp Fabrics. The r esulting types of preforms will be analysed on different approximation levels (micro / meso / macro modelling) to take inhomogeneous fibre distribution and waviness into account. To fulfil the objectives within a limited time (and cost) scale, the linking and integration of different stand-alone solutions in the tool chain is proposed thus creating an open flexible interface for fluent data exchange and communication. The alternative to develop new multi purpose software would be prohibitively costly. The main value is therefore gained for the user of textile composites. ITOOL can set up a standard for testing, modelling and simulation with minimized interference and without data loss and by this reply to the market demands. Further impact of the enhanced simulation capabilities will be a distinct reduction of at least 20% in necessary testing effort as well as a lead time reduction of more than 15%. The proof of this concept will be performed for different application examples in Aeronautics and summarize d in guidelines, design rules and educational tools.
