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.

芯层和表层由不同材料组成的夹层结构，在很大程度上满足了移动结构轻量化的要求，同时还具有吸热、吸声等附加功能，在技术应用上具有优势。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。在此提交的延续提案中，计划在一个步骤中可持续且安全地集成材料组合，因此仅需要一个热处理步骤，并且显着减少了加工步骤的数量。此外，计划通过本地插入元素来本地调整功能。生产分层夹层结构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) 和高分子材料与塑料工程研究所 (PuK) 的工作组重点关注工艺工程和材料科学问题。应用力学研究所（ITM）的固体力学小组致力于建模和仿真领域以及相关基础实验的实现，以对此类金属-聚合物-金属夹层结构的行为进行建模和仿真。
