Development and modeling design and process guidelines for FDM-structures for the partial reinforcement of hybrid structures

该项目的目的是确定fdm结构的设计和工艺指南，这些指南针对特定的负载情况和应使用对轻量化部件的部分加固进行对齐。根据钢筋结构的设计，有针对性地增加强度和刚度，以尽可能低的重量轻量化应用。除了对fdm零件内部结构的特定载荷情况进行调整，采用不同的参数进行分层，fdm零件的设计也应有所变化。强度特性的分析应通过不同的机械试验（拉伸、压缩、弯曲、冲击等）来进行，以便可以确定fdm部件的现有内部结构在不同载荷情况下的强度和刚度。因此，将为fdm结构制定具体的荷载设计和工艺指南。此外，根据fdm零件的各自内部结构对强度进行建模。该模型为当前荷载情况下的强度分析提供了支持。最后将在一个真正的轻量化部件上验证设置设计和工艺指南。为此，应生产由两种不同聚合物组成的杂化组分，使fdm结构可用作局部增强。作为一个真正的组件，GITBlow部分将被使用，而较薄的材料区域被加强。对于该混合组件，将进行不同的机械测试。

The aim of this project is the determination of design and process guidelines for FDM-structures, which are aligned for specific load cases and shall be used for a partial reinforcement of lightweight parts. According to the design of the reinforcement structure a targeted increase of the strength and the stiffness shall be achieved, with the lowest weight possible for the lightweight application. In addition to the adjustment for specific load cases of the inner part structure of the FDM-part by using different parameters for the layer generation, the design of the FDM-part shall be varied.The analysis of the strength properties shall take place by means of different mechanical tests (tensile, compression, flexural, impact, etc.), so that the respective strength and stiffness for different load cases can be determined for the present inner part structure of the FDM-part. As a result a set-up of specific load design and process guidelines for the FDM-structured will be made. Additionally a modeling of the strengths according to the respective inner part structure of the FDM-parts will take place. This modeling shall be used as a support for the strength analysis against the present load cases.At last the set-up design and process guidelines will be verified on a real lightweight part. For this a hybrid component consisting of two different polymers shall be produced, so that the FDM-structure can be used as a partial reinforcement. As a real component a GITBlow part will be used, whereat the thinner material area is reinforced. For that hybrid component different mechanical tests will be made.
