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.

该项目拟议第二阶段的目标是以可重复的质量生产开放的网状和闭合的多轴向经编织物预制件，这些预制件具有复杂的三维几何形状，没有波纹。在一期工程取得成功成果的基础上，二期工程拟开展的PreSearch活动的基础是力调节NC经纱输送和道夫装置的纺织技术改进，以及针织工艺参数对三维表面形成影响的基础研究。实现连续工艺流程链(逆向工程)的必要基础是更好地了解所用材料的加工行为、必要的计算方法和相应的加工技术发展。此外，这些开发的方法和程序可以转移到其他纺织技术，如纱线编织或多层针织。这些新颖的基于形状的纺织预制件使其适合用作具有矿物或塑料基基的复杂空间复合材料、木质复合材料和弹性体的增强部件。
