介绍了两种在一个工艺步骤中实现纤维金属层板(FML)部件原位杂交的创新工艺。在第一道工序中，湿法模压与拉深相结合。在第二道工序中，拉深与树脂传递模塑(RTM)相结合。这些工艺的好处之一是，由于使用了低粘度的单体混合物，直接在金属坯料之间聚合，因此FML的成型行为更好。对此类部件的制造进行了详细的概述。在论证了工艺可行性后，对三维零件的几何形状和成形行为进行了分析。结果用于设置工艺窗口和为工艺设置推荐指南。利用原位杂交技术，可以在不使用预固结锻造材料的情况下，成功地制造出三维零件，从而获得了材料选择的高度灵活性。
Two innovative processes for the in-situ hybridization of fiber metal laminate (FML) components in one process step are presented. In the first process, the wet compression molding is combined with deep drawing. In the second process, deep drawing is combined with resin transfer molding (RTM). One of the benefits of these processes is a better forming behavior of the FML due to the use of a low viscous monomer mixture which polymerizes directly between the metal blanks. A detailed overview on the manufacturing of such components is given. After showing the process feasibilities, the 3-dimensional components are analyzed regarding their geometry and their forming behavior. The results are used to set a process window and to set a recommended guidance for the process. With the help of the in-situ hybridization, 3-dimensional parts could be produced successfully without using pre-consolidated wrought material, so that a high flexibility of the materials’ choice can be obtained.
