Grey Ghost Gear of Canada (GGGC) is a manufacturer of protection products that incorporate ceramics, where their main function is to defeat incoming projectiles with their high stiffness and hardness, and subsequent ability to dissipate impact energy through fracture. In this proposed two-year project, the University of Alberta (UofA) will lead a project in collaboration with GGGC and Defence Research and Research Development Canada (DRDC) to define key microstructure and mechanical property metrics of silicon carbide (year 1) and alumina oxide (year 2) materials that exhibit superior ballistic performance. These metrics will be used during solicitations of materials from suppliers. To accomplish our objective, we pursue three tasks:.Material Characterization: Evaluate microstructural features (e.g., pores) and chemical c mpositions using Scanning Electron Microscopy tools. 2.Experimentation: Evaluate the strength, stiffness, fracture toughness, hardness, and failure behavior. We will also perform ballistic experiments at HP White on both bare tiles and armor packages, where we will track performance outcomes (e.g., defeat/not defeat, backface deformation). 3.Application of Results: Data from Task 1 and 2 will aid in the development of computational models of ceramic behavior at DRDC. These models will provide additional insights into ceramic \ performance through impact simulation. When complete, we will link ballistic performances with microstructure and mechanical property metrics through the development of test and models, and this will provide insights in the metrics that govern ballistic performance. The transfer of this research to industry will provide competitive advantages to GGGC and others in defense, aerospace, and natural resource industries who are seeking to develop next-generation materials. At the same time, this research will provide some of the most c mplete set of data on microstructure, mechanical, properties, failure, and impact performance in the literature.

加拿大的Gray Ghost Gear（GGGC）是融合陶瓷的保护产品的制造商，其主要功能是用高刚度和硬度击败传入的弹丸，并随后通过裂缝消散影响能量的能力。在该建议的为期两年的项目中，艾伯塔大学（UOFA）将领导一个与GGGC和加拿大国防研究与研究发展开发（DRDC）合作的项目，以定义关键的微观结构和 碳化硅（1年级）和氧化氧化铝（2年级）材料的机械性能指标，具有出色的弹道性能。这些指标将在供应商征集材料时使用。为了实现我们的目标，我们执行三个任务：。材料表征：评估微结构特征（例如毛孔）和化学 c使用扫描电子显微镜工具的mpositions。 2.经验：评估强度，僵硬，断裂韧性，硬度和故障行为。我们还将在裸露的瓷砖和装甲套件上在HP White上进行弹道实验，在那里我们将跟踪性能成果（例如，失败/不打败，背面变形）。 3.结果的应用：任务1和2的数据将有助于开发DRDC的陶瓷行为计算模型。这些模型将通过冲击模拟为陶瓷性能提供更多的见解。完成后，我们将通过开发测试和模型将弹道性能与微结构和机械性能指标联系起来，这将提供有关控制弹道性能的指标的见解。这项研究向工业的转移将为寻求开发下一代材料的国防，航空航天和自然资源行业提供竞争优势。同时，这项研究将提供一些有关C的最多C Mplete数据集 文献中的微观结构，机械，特性，失败和影响性能。
