Shape variable composite structures having defined stiffness are subject of investigation of international research groups. One approach to avoid the contradiction between the implementation of structural flexibility on the one hand and stiffness and strength on the other hand within one and the same structure are pressure-activated cell and honeycomb structures. These include pressure-activated cellular structures (PACS), which have so far only been investigated theoretically.The aim of the research project is to gain theoretical and experimental knowledge necessary for the design, manufacture and testing of integrally textile-engineered PACS.In their joint research hypothesis, the partners are pursuing the goal of researching a theoretically designed PACS in textile-technical integral construction, to provide it with efficient pressurizing and thus to generate a flexible PACS with curvature radii of less than 250 mm, with the same aerodynamic effectiveness and an overall weight advantage of 30 %, exceeding conventional arched flaps.

具有确定刚度的形状可变复合材料结构是国际研究小组的研究课题。避免在同一结构内一方面实现结构柔性与另一方面实现刚度和强度之间的矛盾的一种方法是压力激活单元和蜂窝结构。其中包括迄今为止仅在理论上研究的压力活化蜂窝结构（PACS）。该研究项目的目的是获得设计、制造和测试一体化纺织工程PACS所需的理论和实验知识。在他们的联合研究假设中，合作伙伴的目标是研究理论设计的PACS在纺织技术一体化结构中的应用，从而产生曲率半径小于250 mm的柔性PACS，具有相同的空气动力学效率和30%的总重量优势，超过传统的拱形襟翼。
