In recent decades, the aerospace, automotive, biomedical, civil, sports equipment fields, for example, have been using composite materials. Composite materials production and use constitute a multi-billion dollar industry. Composite materials have revolutionized a number of industries due to their lightweight, high mechanical performance, and environmental resistance. Such characteristics have led to important energy and material savings. Braids are one of the oldest textiles. Recently, high end industries, have explored, or are using, braided composite materials as one possible option in product and component development. Braided composites are very versatile materials, highly adaptable to a number of applications. The uptake of braided composites has been relatively slow compared to other composite material manufacturing processes. A manufacturing technique that is as versatile as braiding comes with a large number of considerations and complexities. The reasons few industries are using braided composites is that there are a number of challenges in developing and using advanced braided composite material: quality of manufacturing, comprehensive understanding of their properties and behaviour under complex and fatigue loading, and as a result, predicting their properties. For those interested in considering braided composites, the overall costs of the systems and the research required, often makes it a low return on investment solution. However, if these challenges are successfully addressed in a state-of-the-art equipped research facility, braiding can become a staple of advanced manufacturing for a very board range of industries.**My research program in composite materials focuses on better understanding the behaviour and production of primarily two-dimensional braided composite materials, as well as translating our related discoveries to industry. In the past 10 years, my team and I at the Multipurpose Composite Group, have been making significant headway in meeting the braided composite manufacturing, mechanical testing, and mechanical property prediction challenges. This NSERC Discovery Grant proposal, which builds on the successes of previous grants, aims to address in the short term the following braided composite material challenges: using a machine vision system to improve the quality of the manufacturing process and braided composite end product; understanding the behaviour of braided composites under complex and fatigue loading scenarios; and develop new models, based on accurately measured geometry, to better predict mechanical properties as well as fatigue behaviour.**My group has an exceptional environment (equipment and collaborators) in which to learn, grow and become academic and/or industrial leaders. For the next five years I expect to train 3 PhDs and 3 MSc, as well as 2 undergraduate students per year with this grant.

近几十年来，例如，航空航天，汽车，生物医学，民用，运动器材领域一直在使用复合材料。复合材料生产和使用构成了数十亿美元的行业。复合材料由于其轻巧，机械性能和环境抵抗力而彻底改变了许多行业。 这种特征导致了重要的能源和物质节省。辫子是最古老的纺织品之一。 最近，高端行业已经探索或正在使用编织的复合材料作为产品和组件开发中的一种可能选择。 编织的复合材料是非常通用的材料，非常适合许多应用。与其他复合材料制造工艺相比，编织复合材料的吸收相对较慢。 与编织一样用途广泛的制造技术带有许多考虑因素和复杂性。很少有行业使用编织的复合材料的原因是，在开发和使用先进的编织复合材料方面存在许多挑战：制造质量，对其在复杂和疲劳负荷下的特性和行为的全面理解，结果预测了它们的性质。 对于那些有兴趣考虑编织复合材料的人，系统的总成本和所需的研究通常会使投资解决方案回报率较低。但是，如果这些挑战在配备最先进的研究机构中成功解决，那么编织可能会成为一系列董事会范围的高级制造业。在过去的10年中，我和我在多功能综合小组的团队在满足编织的复合制造，机械测试和机械性能预测挑战方面一直取得了重大进展。 这项基于以前赠款的成功的NSERC Discovery Grant提案旨在在短期内解决以下编织的复合材料挑战：使用机器视觉系统来提高制造过程的质量和编织的复合最终产品；了解在复杂和疲劳载荷场景下编织的复合材料的行为；并基于精确测量的几何形状开发新模型，以更好地预测机械性能以及疲劳行为。在接下来的五年中，我希望每年培训3次博士学位和3个MSC，以及每年的本科生2名。
