Online prepreg system for the production of fibre-reinforced semi-finished products

应用的设备实现了一个在此形式中尚未存在的概念。它解决了用预浸料制造纤维复合材料的一些最紧迫的问题。这些问题包括太高的周期时间、太高的材料和单位成本、太多的关键浪费和太少的灵活性。这使得该设备的应用目标实现如下：预浸料是准时/按顺序生产的，不再需要后勤和能量复杂的预浸料深冻储存。由于灵活的生产（机器人，单独的树脂混合厂），预浸料也可以小批量生产，这增加了可行变体的数量。纺织品半成品经裁切至近净形，再浸渍至近净形。所产生的废物没有浸渍树脂，可以在封闭循环中回收。主要研究方向为工艺技术和材料科学。首先，执行概述的进程和确定其潜力是首要的考虑事项。随后，重点是半成品在非高压灭菌技术中的适用性，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。

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.
