Integrated method for process planning and structural design of composite structures.

该项目的研究假设是，通过调整方法，有可能用纤维复合材料开发出轻质结构，不仅达到低质量特性，而且还可以有效地制造。因此，与金属设计相比，可以降低较高的工程和生产成本。其目的是开发和评估一种高性能纤维复合材料结构的自动化设计及其高效生产的方法。这包括结构设计、生产计划以及它们之间的相互作用。溶液的质量由结构标准(质量)和生产标准(生产成本)决定。与传统方法相比，及早考虑生产方面可以避免在开发过程的后期阶段进行成本密集的迭代。传统方法只能在概念阶段选择有限数量的解决方案，因为所有这些解决方案都将在随后的开发步骤中得到充分开发。然而，这种方法能够考虑更多在结构和生产方面不同的解决方案。通过并行地逐步进行所有解决方案的设计，可以限制总体开发工作。在这个过程中，应用的设计和评估方法的复杂性增加了，而考虑的解决方案的数量减少了。因此，复杂方法仅用于在前面的选择中符合条件的较少数量的解决方案。作为应用实例，选择了碳纤维增强塑料(CFRP)制造的飞机机身结构的开发，因为它具有极端的要求，只有使用一种两个学科都有强烈交互作用的方法才能以最佳的方式满足这些要求。这项研究是基于两个研究所自2010年以来在高性能CFRP结构生产领域的跨学科合作成果。

The projects research hypothesis is that, with an adjusted method, it is possible to develop lightweight structures out of fiber composite material to not only reach low mass properties but also to be efficiently manufacturable. As a consequence, high engineering and production costs compared to metal designs can be reduced. The objective is to develop and evaluate a method for the automated design of high-performance fiber composite structures and their efficient production. This comprises structural design, production planning and their interaction. The quality of a solution is determined by structural criteria (mass) as well as production criteria (production cost). Compared to conventional methods, an early consideration of production aspects prevents cost-intensive iterations in later stages of the development process. Conventional methods can only select a limited amount of solutions in the concept phase since all of them are to be fully developed in the following development steps. This method, however, is able to consider a higher number of solutions that differ in structural and production aspects. The overall development effort can be limited by gradually proceeding through the design of all solutions in parallel. In the course of this process the complexity of applied design and assessment methods is increased while the number of considered solutions is decreased. Therefore, complex methods are only used for a smaller number of solutions that qualified in preceding selections. As an application example the development of an aircraft fuselage structure made of carbon fiber reinforced plastic (CFRP) is chosen, since it has extreme requirements that can only be met in an optimum way by using an approach with strong interaction of both disciplines. The research is based on achievements of an interdisciplinary cooperation of the institutes in the field of high performance production of CFRP-structures practiced since 2010.
