Hybrid Consolidation

该项目采取了一种新的研究方法，在很大程度上将纤维的嵌入与复合材料结构的制造分离开来。时间解耦通过粘结固结半成品来实现。该过程中的一个重要方面是关于半成品的几何质量和材料质量的质量保证。显然，材料的预固结限制了半成品的柔性，这反过来又限制了复杂结构几何形状的实现。专注于大型二维甚至略微弯曲的承重结构，如网格框架，可以应用加固带的铺设和粘合。通过这种新颖的方法避免了波动和纤维波纹。可以控制铺叠的整体精度。该项目追求的基本研究假设是，加固的狭缝带的层压产生与由预浸带制成的层压板相同的机械性能。

The project takes as novel research approach a largely decoupling of the imbedding of the fibers from the manufacturing of composite structures. The temporal decoupling is realized by bonding consolidated semi-finished products. An important aspect in this process is the quality assurance with regard to the geometric quality of the semi-finished product and the quality of material. Obviously, the pre-consolidation of the material restricts the flexibility of the semi-finished product which, in turn, restricts the realization of complex structural geometries. The focus on large two-dimensional or even slightly curved load-bearing structures like grid frameworks enables the application of the lay-up and bonding of consolidated tapes. Undulations and fiber waviness are avoided through this novel approach. The global precision of the layup can be controlled. The project pursues as fundamental research hypothesis that the lamination of consolidated slit tapes yields the same mechanical properties as laminates made from prepreg tapes.
