纤维增强塑料（FRP）的使用有助于有效实现轻量化设计，因为它们具有出色的特定机械性能。RTM工艺提供了很大的设计自由度，并允许在制造过程中集成功能元件。嵌入式金属元件，即所谓的插入件，可用于处理向结构部件的载荷传递。与其他连接技术相比，这些元件具有独特的特性。例如，可拆卸的连接可以在插件的帮助下建立。由于纤维连续性未被中断，因此FRP部件不必钻孔，因此没有局部支承应力。本文旨在表征玻璃钢零件中的金属嵌件。这些部件采用RTM工艺制造，并使用专门调整的RTM模具，可更换不同刀片几何形状的刀片盒。插入件由带有焊接衬套的金属板制成，并在预成型过程中嵌入。固化FRP试样在不同的负载条件下进行测试，以评估其适用于各种应用领域。此外，插入件的金属板的直径和厚度以及FRP的厚度是变化的，以确定它们对拉伸载荷下的破坏行为和承载能力的影响。
The use of fiber-reinforced-plastics (FRP) contributes to an efficient implementation of lightweight design due to their outstanding specific mechanical properties. The RTM process offers great design freedom and allows the integration of functional elements during manufacturing. Embedded metal elements, so-called inserts, can be used to deal with the load transfer to structural parts. These elements have distinctive characteristics in comparison to other joining technologies. For example, detachable connections can be established with the help of inserts. Due to the fiber continuity not being interrupted and, subsequently, the FRP parts not having to be drilled, there is no local bearing stress. This paper aims at the characterization of metal inserts in FRP parts. The parts are manufactured using the RTM process with a specially adapted RTM mold with exchangeable cartridges for different insert geometries. The inserts are made of metal sheets with welded bushings and are embedded during preforming. The cured FRP specimens are tested under different load conditions to evaluate their suitability for various fields of application. Furthermore, the diameter and thickness of the metal sheet of the insert as well as the thickness of the FRP are varied to identify their influence on the failure behavior and load capacity under tensile loads.
