The goal of the proposed second phase of the project is the production in a reproducible quality of open net-shaped as well as closed-surface Multiaxial Warp Knitted Textile preforms with complex three-dimensional geometries that are ripple free. Based on the successful results achieved during the first phase of the project, the fundament of the proposed presearch activity in the second phase of the project is the Textile technological enhancement of force regulated NC- Warp yarn delivery and Doffing unit as well as the basic research on the influence of the Knitting process parameters on the 3-D surface formation. The necessary foundation for the realization of a continuous Technological process chain (Reverse Engineering) results from a better understanding of the processing behavior for the materials used, the necessary Calculation methods and the corresponding process technology developments. Furthermore, these developed methods and procedures can be transferred to other Textile technologies, such as Leno weaving or Multilayer Knitting. These novel form-based textile preforms make themselves suitable for their application as reinforced components in complex spatial composites with a mineral or a plastic-based matrix, wooden composites and elastomers.

该项目第二阶段的目标是以可重复的质量生产开放式网状和封闭表面的多轴经编纺织预成型件，该预成型件具有复杂的三维几何形状，且无波纹。 在项目第一阶段取得的成功成果的基础上，项目第二阶段拟开展的研究活动的基础是力调节NC-经纱输送和落纱装置的纺织技术改进以及基础研究针织工艺参数对 3-D 表面形成的影响。实现连续技术工艺链（逆向工程）的必要基础来自于对所用材料的加工行为、必要的计算方法和相应工艺技术开发的更好理解。此外，这些开发的方法和程序可以转移到其他纺织技术，例如纱罗编织或多层针织。这些新颖的基于形状的纺织预成型件适合作为具有矿物或塑料基体的复杂空间复合材料、木质复合材料和弹性体的增强部件的应用。
