Single-step production of metal-polymer-metal sandwich structures with a fiber-reinforced core: experiment, modeling and simulation

夹层结构由芯层和表层的不同材料组成，在很大程度上满足了移动结构中轻质结构的要求，同时提供了额外的功能，如吸热或吸声，这在技术应用中带来了优势。金属覆盖层和纤维增强聚合物芯材料的耦合提供了高度的功能集成，是各种研究项目的主题。在这里提交的延续提案中，计划在一个步骤中可持续和安全地整合材料组合，因此只需要一个热步骤，并大大减少了加工步骤的数量。此外，计划通过本地插入元素在本地调整功能。夹层结构生产项目的跨学科任务由三个项目合作伙伴负责。冶金研究所（IMET）和高分子材料和塑料工程研究所（PuK）的工作组将工作重点放在工艺工程和材料科学问题上。应用力学研究所（ITM）的固体力学组涉及建模和仿真领域以及相关基础实验的实现，以建模和仿真这种金属-聚合物-金属夹层结构的行为。

Sandwich structures, made up of different materials in the core and surface layers, meet the requirements of lightweight construction in moving structures to a high degree, while offering additional functionalities such as thermal or acoustic absorption, which bring advantages in technical applications. The coupling of metallic cover layers and fiber-reinforced polymer core material offers a high degree of functional integration and is the subject of various research projects. In the continuation proposal submitted here, the sustainable and secure integration of the material combinations in one step is planned, thus only one thermal step is required and the number of processing steps is significantly reduced. Additionally, it is planned to adjust the functionality locally by means of local insert elements. The interdisciplinary task of the project for the production of layered sandwich structures is being handled by three project partners. The working groups of the Institute of Metallurgy (IMET) and the Institute of Polymer Materials and Plastics Engineering (PuK) focus their work on process engineering and materials science issues. The Solid Mechanics group of the Institute of Applied Mechanics (ITM) deals with the field of modeling and simulation as well as the realization of related basic experiments to model and simulate the behavior of such metal-polymer-metal sandwich structures.
