Production Metal Plastic Hybrid Structure

项目摘要

The combination of different materials for the production of high performance parts allows for a broad range of functionality and applicability. Thus, the use of metals and plastics for hybrid structures has grown more and more important within the last years, as their respective complementary characteristics can be exploited in the fields of lightweight construction, acoustic damping and others. However, the number of production processes allowing for a common manufacturing of both materials is limited. Therefore, the potential of metal-plastic-hybrids is not yet fully used.The scope of this research project is to develop a new way to process metal and plastic in one single production step via impact extrusion. Such a process does not yet exist. The general feasibility of this concept has already been shown in a preceding experimental study. The first steps within this research project will be to further explore separate aspects of the process e.g. the input of mechanical energy for the plasticization of the polymer phase and its flow behavior during the deformation. From these results the design of the impact extrusion die will be deducted. In an iterative loop, parts will be produced and analyzed in regard to their properties. The findings will be used to further optimize the process and define its potentials and limitations. Finally, metal-plastic-hybrid parts will be produced with optimized process parameters and their weight specific mechanic properties and damping characteristics will be determined.

不同材料的组合可用于生产高性能部件，从而具有广泛的功能和适用性。因此，在过去的几年里，金属和塑料在混合结构中的使用变得越来越重要，因为它们各自的互补特性可以在轻质建筑、声学减振等领域得到开发。然而，允许两种材料共同制造的生产工艺的数量是有限的。因此，金属-塑料-杂化材料的潜力还没有得到充分利用。本研究项目的范围是开发一种通过冲击挤出一步加工金属和塑料的新方法。这样的过程还不存在。这一概念的总体可行性已经在之前的实验研究中得到了证明。该研究项目的第一步将是进一步探索工艺的不同方面，例如，聚合物相塑化的机械能输入及其在变形过程中的流动行为。根据这些结果，可以推断出冲击挤压模具的设计。在迭代循环中，将产生部件，并根据部件的属性进行分析。调查结果将被用来进一步优化这一过程，并确定其潜力和局限性。最后，在优化的工艺参数下，生产出金属-塑料-混杂零件，并确定其重量比力学性能和减振特性。
