In an effort to reduce CO2 emissions and resources, more and more manufacturing companies are following the philosophy of lightweight design. Various strategies can be pursued, such as the use of components with high specific strength, load-adapted structures or functional integration. This poses particular challenges for the flexibility of the forming processes, for example to enable a local variation of the material and the adjustment of varying local material properties. Based on this, various methods arise to meet the requirements for components. These include so-called tailoring, the use of high-strength materials, thermally assisted processes and the use of composite components. Composite components make it possible to combine specific material properties in a targeted manner. The aim of this project is the production, grading and incremental forming of composite tubes in a single process step. The aim is to produce composites with oxidation-inhibiting outer tubes and hardenable inner tubes. The planned implementation is based on temperature-assisted incremental tube forming and subsequent tempering, in order to produce components with variable bending radii and cross-sections and properties adapted to requirements along the longitudinal axis. On the basis of the state of the art and the project-specific preliminary work, it will be investigated whether simultaneous composite production and forming generates synergies that lead to improved and more complex products. The process could be used to produce composite components with properties tailored to requirements in terms of mechanical loads and/or chemical resistance, which are either impossible to produce using other known processes or can only be produced at considerably greater expense. The resulting composite strength is to be described by analytical or semi-analytical models.

为了减少二氧化碳排放和资源，越来越多的制造公司开始遵循轻量化设计的理念。可以采取各种策略，例如使用具有高比强度的组件，负载适应结构或功能集成。这对成形过程的灵活性提出了特别的挑战，例如，使材料的局部变化和局部材料特性的调整成为可能。在此基础上，出现了满足组件要求的各种方法。这些包括所谓的剪裁、高强度材料的使用、热辅助工艺和复合部件的使用。复合组件使得以有针对性的方式组合特定材料特性成为可能。该项目的目的是生产，分级和增量成形的复合管在一个单一的工艺步骤。目的是制备具有抗氧化外管和可硬化内管的复合材料。计划的实施是基于温度辅助的增量管成形和随后的回火，以生产具有可变弯曲半径、横截面和性能的部件，以适应纵向轴向的要求。根据目前的技术状况和具体项目的初步工作，将调查复合材料的同时生产和成型是否产生协同作用，从而产生改进的和更复杂的产品。该工艺可用于生产具有根据机械负荷和/或耐化学性要求定制的性能的复合部件，这些部件要么无法使用其他已知工艺生产，要么只能以相当高的成本生产。所得的复合强度用解析或半解析模型来描述。
