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

申请的设备实现了一个在此形式中尚不存在的概念。它解决了用预浸料制造纤维复合材料中一些最紧迫的问题。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。这使得该设备实现的目标如下：预浸料的准时/恰好按顺序生产，不再需要复杂的物流和能量方面的预浸料的冷冻储存。由于灵活的生产(机器人，单独的树脂混合工厂)，预浸料也可以小批量生产，这增加了可行的品种数量。纺织半成品被切割成近净形状，然后也浸渍到近净形状。产生的废物不用树脂浸渍，可以闭合循环回收。研究兴趣主要集中在工艺技术和材料科学领域。首先，执行概述的进程并确定其潜力是考虑的首要问题。随后，重点讨论了半成品对非高压罐技术的适用性、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材料塑料中。

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.
