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.

由核心和表面层中不同材料组成的三明治结构在高度的移动结构中满足轻巧结构的要求，同时提供了其他功能，例如热吸收或声学吸收，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核心材料的耦合提供了高度的功能整合，并且是各种研究项目的主题。在此处提交的持续提案中，计划了一个步骤的材料组合的可持续和安全整合，因此只需要一个热步骤，并且处理步骤的数量大大减少。此外，计划通过本地插入元素在本地调整功能。该项目生产分层三明治结构的跨学科任务是由三个项目合作伙伴处理的。冶金研究所（IMET）和聚合物材料与塑料工程研究所（PUK）的工作组集中在过程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，以及实现相关的基本实验，以模拟和模拟此类金属 - 聚合物 - 金属三明治结构的行为。
