The working group Biomaterials & Lightweight Construction at the University of Applied Sciences Stralsund, affiliated in the School of Mechanical Engineering - in the Materials and Manufacturing Technology division, is applying for a high-resolution X-ray microCT for the volumetric 3D reconstruction of samples or component structures. The research area Biomaterials & Lightweight Construction is embedded in two main research areas at the University of Applied Sciences Stralsund: (1) health technologies with the competence field biomaterials and (2) technical systems and energy efficiency with the competence areas lightweight construction and material science and is therefore in the special interest of the University of Applied Sciences. The focus within the field of biomaterials is on magnesium alloys as metallic biomaterial. The working group is intensively researching on biodegradable magnesium alloys, their corrosion behavior with a focus on corrosion morphology. Possible applications of this so-called biomagnesium are bone screws, clips for wound closure, bone nails, pins, stents and wires. Here a uniform corrosion rate adapted to its application is essential. First products are already available on the market. The School of Mechanical Engineering is currently planning to establish an area of specialization in health technologies; a microCT fits perfectly to the intention to strengthen this area. Lightweight construction has been in the interest of the school for many years, automotive engineering is an established specialization. Another focus of the working group is joining of fiber composite materials to high-strength wrought aluminum alloys in the context of multi-material designs as well as the joining of similar and dissimilar wrought aluminum alloys in vehicle and aircraft constructions. The working group is also experienced in the development and chemical adaptation of biocompatible materials for additive manufacturing. The focus is on the development of acrylates for photopolymerization, especially stereolithography. The requested microCT is intended to give information on the internal structure of metallic lightweight alloys based on magnesium and aluminum, as well as of fiber composite plastics and polymer-based materials. This applies both in the initial state and as a result of mechanical (static, cyclical) and corrosive testing. This enables a correlation of the state/quality of the material (microstructure, manufacturing defects) with the resulting properties and allows the best basis for material and process optimization. The University of Applied Sciences Stralsund does not have an X-ray microCT facility yet. The near region of Stralsund has not got such a devices of the requested performance class or either. In addition to the given collaborations, the new system offers the possibility to expand new research collaborations.

施特拉尔松德应用科学大学的生物材料与轻质结构工作组隶属于机械工程学院-材料与制造技术部门，正在申请高分辨率X射线microCT，用于样品或组件结构的体积3D重建。研究领域生物材料和轻质结构嵌入在施特拉尔松德应用科学大学的两个主要研究领域：（1）健康技术与能力领域生物材料和（2）技术系统和能源效率与能力领域轻质结构和材料科学，因此是应用科学大学的特殊兴趣。镁合金作为金属生物材料是生物材料领域的研究热点。该工作组正在深入研究可生物降解的镁合金，其腐蚀行为，重点是腐蚀形态。这种所谓的生物镁可能的应用是骨螺钉、伤口闭合夹、骨钉、销钉、支架和金属丝。在这里，与其应用相适应的均匀腐蚀速率至关重要。第一批产品已经在市场上销售。机械工程学院目前正计划建立一个健康技术专业领域;微型CT完全符合加强这一领域的意图。轻量化建筑多年来一直是学校的兴趣所在，汽车工程是一个既定的专业。工作组的另一个重点是在多材料设计的背景下将纤维复合材料连接到高强度锻造铝合金上，以及在车辆和飞机结构中连接类似和不同的锻造铝合金。该工作组还在增材制造的生物相容性材料的开发和化学适应方面经验丰富。重点是光聚合，特别是光固化丙烯酸酯的发展。所要求的microCT旨在提供关于镁和铝基金属轻质合金以及纤维复合塑料和聚合物基材料的内部结构的信息。这既适用于初始状态，也适用于机械（静态、循环）和腐蚀性测试。这使得材料的状态/质量（微观结构、制造缺陷）与所产生的性能相关联，并为材料和工艺优化提供最佳基础。施特拉尔松德应用科学大学还没有X射线microCT设备。施特拉尔松德附近地区没有达到要求的性能等级的设备。除了现有的合作外，新系统还提供了扩大新的研究合作的可能性。
