ABSTRACT

The current focus on low-cost and high strength materials for advanced engineering applications attracted the research on the development of metal matrix syntactic foams. It is due to its highly tailorable properties. They are lightweight, higher ductility, quasi-static and dynamic compressive strength, better damping and energy absorption behavior and plateau strength. Different hollow particles were tried in the development of metal-based closed-cell syntactic foams such as cenosphere, ceramic, hollow glass particles, and expanded clay particles. Many researchers studied the physical and mechanical properties of polymer matrix syntactic foam. Very few reports are available on metal matrix syntactic foams, which remain a challenge to explore the properties. This present study provides a comprehensive insight into metal matrix syntactic foams, fabrication techniques and its influence on the mechanical properties, future scope, and its applications.

摘要

目前对用于先进工程应用的低成本和高强度材料的关注吸引了对金属基复合泡沫材料开发的研究。这是由于其高度可定制的特性。它们重量轻、延展性更高、准静态和动态压缩强度、更好的阻尼和能量吸收行为以及平台强度。在金属基闭孔复合泡沫的开发中尝试了不同的中空颗粒，例如煤胞、陶瓷、中空玻璃颗粒和膨胀粘土颗粒。许多研究人员研究了聚合物基复合泡沫的物理和机械性能。关于金属基复合泡沫的报道很少，这仍然是探索其性能的挑战。本研究提供了对金属基复合泡沫的全面了解，
