The focus of TP4 (Research group Ziegmann) is to investigate the influence of nanoparticle (NP) in resin systems regarding the process and part manufacturing. The critical research aspects of the TP4 are focused on the process technological design of material (NP suspension and preform) regarding the important material (filament distance, permeability) and process parameters (draping, compaction) as well as development of new impregnation strategies in Liquid Composite Molding (LCM) processes for the manufacturing of complex fiber composite structures with defined nanoparticle distribution, in order to achieve targeted locally adjustable property profiles. In the second funding period, the concepts that are developed based on the plane laminates will be transferred to adjustment of the gradient in complex structures. For the manufacturing of complex structures, a binder system is necessary for the draping and fixing of textiles on the complex shaped tools. In parallel to conventional binder systems, a new, epoxy-solvable, electrospun, thermoplastic supporting fiber for nanoparticles (Nano Carrier Fiber) will be investigated (development in TP1, research group Sturm/Silbernagl), which could be used as local binder and also as local nanoparticle reinforcement in critical positions in the final structures. The research critical aspects include description of the macro/microporosity of the textiles, permeability investigation in all the three major directions, flow and filtration behavior of the nanoparticles, the flow and cure simulation, as well as visualization of the flow behavior of the nanoparticle, to more specifically, the particle movement during the impregnation process. The investigations in TP4 are based closely on the results from TP1 and TP3 and will deliver in turn the basics to research works of TP2, 5 and 6.

TP4（研究小组Ziegmann）的重点是研究纳米颗粒（NP）对树脂系统对过程和部分制造的影响。 TP4的关键研究方面集中于材料的过程设计（NP悬浮液和预成型），涉及重要的材料（灯丝距离，渗透率）和过程参数（悬垂，压实）以及在液体复合成型（LCM）中开发新的浸渍策略（LCM），以实现特定型号的配置型构造型号，以实现特定的构造型号，以实现定义的分配Nan ananopart，以实现特定的分配均匀分配。在第二个资金期间，基于平面层压板开发的概念将转移到复杂结构中的梯度调整。为了制造复杂的结构，粘合剂系统对于在复杂形状工具上悬垂和固定是必需的。与传统的粘合剂系统平行，将研究一种新的，可溶解的，可播种，热塑性支撑纳米颗粒的纤维（Nano载体纤维）（TP1的开发，研究小组Sturm/Silbernagl），可以用作局部粘液器，也可以用作局部纳米纳米机构在局部纳米机构中的核心稳定位置。研究的关键方面包括描述纺织品的宏观/微孔度，在所有三个主要方向上进行的渗透率研究，纳米颗粒的流动和过滤行为，流量和治疗模拟以及纳米粒子的流动行为的可视化，更具体地，在爆发过程中，粒子运动。 TP4中的研究紧密基于TP1和TP3的结果，然后将基础知识传递给TP2、5和6的研究工作。
