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.

通过开发具有独特性能的多孔微结构体系，对新型结构和生物医学材料和复合材料的研究正在取得创新突破。这些材料被广泛应用于从汽车到医疗领域。拟议的工作将对一系列应用的制造和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，通过该小组设计的新工艺创造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骨的临时结构替代物，在愈合后具有生物相容性，并自然地被重新吸收到体内，没有任何不良影响。一种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续工艺，这是拟议工作的一个重点。这项研究的另一个方面是基于对铝合金泡沫加工的改进，这些泡沫铝合金正被应用于汽车车身结构部件，能够吸收汽车碰撞产生的巨大冲击能量。一个新的研究方向包括采用粉末冶金加工技术的创新软磁复合材料(SMCs)，用于地面车辆运输用电机的新设计。这些材料有可能通过3D打印来制造。所有这些研究都对加拿大有价值，许多行业将受益，包括汽车供应链和航空航天行业。已经有几家用于结构或功能应用的多孔材料制造商，并不断寻找改进其产品和工艺的方法。此外，随着人口老龄化和提供更持久或更长期解决方案的医疗程序的日益复杂，对更先进和改进的生物材料的需求继续存在，以用于各种新兴和现有的应用。
