Abstract

Efforts to enhance sustainability in all areas of life are increasing worldwide. In the field of manufacturing technology, a wide variety of approaches are being used to improve both resource and energy efficiency. Efficiency as well as sustainability can be improved by creating a circular economy or through energy-efficient recycling processes. As part of the interdisciplinary research group "Light—Efficient—Mobile" investigations on the energy-efficient friction-induced recycling process have been carried out at the department of Forming and Machining Technology at Paderborn University. E.g. using the friction-induced recycling process, different formless solid aluminum materials can be direct recycled into semi-finished products in an energy-efficient manner. The results of investigations with regard to the influence of the geometrical shape and filling rate of the aluminum particles to be recycled as well as the rotational speed of the continuously rotating wheel are explained in this paper. In addition to the recycling of aluminum chips, aluminum particles like powders from the field of additive manufacturing are processed. Based on these results, the future potentials of solid-state recycling processes and their contribution to the circular economy are discussed. The main focus here is on future interdisciplinary research projects to achieve circularity in the manufacturing of user-individual semi-finished products as well as the possibility to selectively adjust the product properties with the continuous recycling process.

摩擦诱导回收过程提高制造技术资源和能源效率的潜力

在世界范围内，加强生活各个领域的可持续性的努力正在增加。在制造技术领域，正在采用各种各样的方法来提高资源和能源效率。效率和可持续性可以通过创建循环经济或通过节能的回收过程来提高。作为跨学科研究小组“光效-移动”的一部分，帕德博恩大学成形与加工技术系对节能摩擦诱导回收过程进行了研究。例如，使用摩擦诱导回收工艺，可以将不同的无形固体铝材料直接回收为半成品，从而节省能源。本文对回收铝颗粒的几何形状、填充率以及连续转轮转速对回收铝颗粒的影响进行了研究。除了回收铝屑，还处理增材制造领域的铝粉等铝颗粒。基于这些结果，讨论了固态回收工艺的未来潜力及其对循环经济的贡献。这里的主要重点是未来的跨学科研究项目，以实现用户个人半成品制造的循环性，以及随着连续回收过程有选择地调整产品特性的可能性。

期刊介绍： The Journal publishes and disseminates original research in the field of material forming. The research should constitute major achievements in the understanding, modeling or simulation of material forming processes. In this respect ‘forming’ implies a deliberate deformation of material. The journal establishes a platform of communication between engineers and scientists, covering all forming processes, including sheet forming, bulk forming, powder forming, forming in near-melt conditions (injection moulding, thixoforming, film blowing etc.), micro-forming, hydro-forming, thermo-forming, incremental forming etc. Other manufacturing technologies like machining and cutting can be included if the focus of the work is on plastic deformations. All materials (metals, ceramics, polymers, composites, glass, wood, fibre reinforced materials, materials in food processing, biomaterials, nano-materials, shape memory alloys etc.) and approaches (micro-macro modelling, thermo-mechanical modelling, numerical simulation including new and advanced numerical strategies, experimental analysis, inverse analysis, model identification, optimization, design and control of forming tools and machines, wear and friction, mechanical behavior and formability of materials etc.) are concerned.
