在这里介绍的项目中，对镁基轻金属泡沫的制备进行了研究和改进。这种泡沫塑料具有极好的质量体积比，因此非常适合作为轻质和有效的增强元件。除了其他功能特性外，它们作为能量吸收碰撞元件的适用性值得特别强调，也是这里研究的重点。在冲击载荷的情况下，在体积减小的过程中，能量很大程度上转化为塑性变形功。虽然金属泡沫本身只具有较低的绝对强度，但通过集成额外的内部增强元件，以夹层结构或复合材料等材料组合的形式使用它们是有利的。本项目采用的是后一种办法。给出了用于表征增强泡沫镁的可行性研究以及金相和力学研究的初步结果。
In the project introduced here, the manufacture of light‐metal foams based on magnesium are investigated and enhanced. Such foams possess an excellent mass‐volume ratio and are therefore perfectly suited as light and effective reinforcing elements. Apart from other functional properties, their suitability as energy absorbing crash elements is to be particularly emphasised and is the focus of the investigations here. In the case of impact loading, the energy is largely transformed into the work of plastic deformation during a reduction in volume. Although metallic foams themselves possess only low absolute strengths, it is expedient to employ them in the form of material combinations like sandwich structures or composites by integrating additional internal reinforcing elements. The latter approach is pursued in the present project. Both the initial results of the feasibility study and also the metallographic and mechanical investigations for characterising reinforced magnesium foams are presented.
