三维（3D）间隔织物由使用热塑性高性能混合纱线的二维（2D）织造织物通过2D织造交联织物连接而构造。间隔织物在高效生产具有可调机械性能的纤维增强塑料复合材料方面具有很大的潜力，可用于轻量化工程中的特定应用。编织的结构和在编织过程中施加在纤维上的应力影响成品复合材料的机械性能。这项研究表明，可以显着控制和调整的机械性能的图案开发的个人2D复合结构从3D间隔织物预制件构造的正交多层编织（非卷曲纤维排列和温和的编织过程）。导电纤维直接编织到2D编织织物的各个层中，因此在生产过程中成功集成。这构成了复合材料中功能集成的基础。编织技术确保了导电纤维的可靠接触，允许传感器网络集成到织物中，用于在线监测纤维增强塑料复合材料部件。
Three dimensional (3D) spacer fabrics are constructed from two dimensional (2D) woven fabrics connected by 2D woven crosslink fabrics using thermoplastic high performance hybrid yarns. Spacer fabrics present great potential in the efficient production of fiber reinforced plastic composites with adjustable mechanical properties targeted for specific applications in Lightweight engineering. The structure of the weave and the stresses placed on the fibers during the weaving process impact the mechanical properties of the finished composite. This study shows that the mechanical properties can be significantly controlled and adjusted by pattern development of the individual 2D composite structures from the 3D spacer fabric preforms constructed of orthogonal multi-layer weaves (non-crimped fiber arrangement and a gentle weaving process). Electrically conductive fibers are woven directly into various layers of the 2D woven fabrics and are therefore successfully integrated during production. This forms the basis for function integration in the composite. The weaving technology ensures a reliable contact of the conductive fibers allowing sensor networks to be integrated into the fabric for online monitoring of the fiber reinforced plastic composite component.
