The device applied for implements a concept that does not yet exist in this form. It solves some of the most urgent problems in fiber composite manufacturing with prepregs. These are too high cycle times, too high material and unit costs, too much critical waste and too little flexibility. This results in objectives which the device applied for realizes as follows:Prepregs are produced just-in-time / just-in-sequence, the logistically and energetically complex deep-freeze storage of prepregs is no longer necessary.Prepregs can also be produced in small batch sizes thanks to flexible production (robots, separate resin mixing plant), which increases the number of feasible variants.Textile semi-finished products are cut to near-net-shape and then also impregnated to near-net-shape. The resulting waste is not impregnated with resin and can be recycled in a closed cycle.The research interest is mainly in the fields of process technology and materials science. First of all, the implementation of the outlined process and the determination of its potential are at the forefront of the considerations. Subsequently, the focus is on the suitability of semi-finished products for out-of-autoclave technologies, new repair concepts in fibre composite technology and the use of prepreg technology to introduce nanoparticles into fibre composite plastics.

所申请的设备实现了一个尚不存在的概念。它解决了纤维复合材料制造中的一些最紧迫的问题。这些都是太长的周期时间，太高的材料和单位成本，太多的关键浪费和太少的灵活性。因此，该设备实现了以下目标：预浸料的即时/即时生产，不再需要物流和能源方面复杂的预浸料深冻存储。由于灵活的生产（机器人，单独的树脂混合设备），预浸料也可以小批量生产，这增加了可行的变体数量。纺织半成品被切割成近净形，然后也浸渍成近净形。所产生的废物不含树脂，可以在封闭循环中回收。研究兴趣主要在工艺技术和材料科学领域。首先，执行所概述的进程并确定其潜力是首要考虑的问题。随后，重点是半成品对高压釜外技术的适用性，纤维复合材料技术中的新修复概念以及使用预浸料技术将纳米颗粒引入纤维复合塑料。
