Innovative Ceramic and Metallic Porous Materials

通过具有独特性能的多孔微结构结构的发展，对新型结构和生物医学材料和复合材料的研究正在创造创新突破。从汽车到医疗领域，这些材料正在得到广泛的应用。拟议的工作将对其制造和一系列应用性能背后的科学知识和理解产生重大影响。生物材料研究将研究骨支架的发展，例如，由该小组设计的新工艺产生的生物可吸收复合泡沫的形式。骨支架作为创伤或骨丢失后的临时结构替代品，在愈合后，支架具有生物相容性，可以自然地重新吸收到体内，没有副作用。分散在乳酸聚合物泡沫中的生物玻璃溶胶-凝胶纳米粉末有望增强后一过程，并且是所提出工作的一个轴的焦点。这项研究计划的另一个方面是基于改进铝合金泡沫的加工，这种泡沫正在寻找能够吸收车辆碰撞产生的巨大冲击能量的汽车车身结构部件的应用。一个新的研究方向是采用粉末冶金加工技术的创新软磁复合材料（SMCs）用于地面车辆运输电动机的新型设计。这些材料有可能通过3D打印制造出来。所有这些研究对加拿大都有价值，包括汽车供应链和航空航天工业在内的许多行业都将受益。一些结构或功能应用的多孔材料制造商已经存在，并不断寻求改进其产品和工艺的方法。此外，随着人口管理和提供更永久或更长期解决方案的医疗程序的日益复杂，对用于各种新兴和现有应用的更先进和改进的生物材料的需求继续存在。

Research into novel structural and biomedical materials and composites is creating innovative breakthroughs through thedevelopment of porous microstructural architectures with unique properties. These materials are finding a wide variety ofapplications ranging from automotive to the medical field. The proposed work will have a significant impact on theknowledge and understanding of the science behind their manufacturing and performance for a range of applications. Thebiomaterials research will study the development of bone scaffolds, for example, in the form of bioabsorbable compositefoams created by novel processes devised by this group. A bone scaffold acts as a temporary structural replacement for bonefollowing trauma or bone loss and, upon healing, the scaffold, is biocompatible and is naturally reabsorbed into the body withno adverse effects. A bioglass sol-gel nano-powder dispersed in a lactic acid polymer foam is expected to enhance the latterprocesses and is the focus of an axis of the proposed work.Another aspects of this research proposal is based on improvementto the processing of aluminumalloy foams which are finding applications as structural auto body parts that are capable of absorbing significant impact energyresulting from vehicle collisions. A new research direction includes innovative Soft Magnetic Composites (SMCs) using powder metallurgy processing techniques for novel designs of electric motors for ground vehicle transportation. These materials have the potential to be manufactured by 3D Printing. All this research is of value to Canada and a number of industries will benefit, including theautomotive supply chain and aerospace industries. Several manufacturers of porous materials for structural or functional applications already exist and are constantly seeking out ways to improve their products and processes. Moreover with anaging population and increasing sophistication of medical procedures which provide more permanent or longer termsolutions, there continues to be a demand for more advanced and improved biomaterials for use in a variety of emerging aswell as existing applications.
