Composite materials production and use constitute a multi-billion-dollar industry having revolutionized a number of fields (aerospace, automotive, biomedical, civil) due to their lightweight, high mechanical performance, environmental resistance, and 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 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 or slow 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. A second broader challenge with braided, and other composite materials, is their environmental impact. There have been a number of efforts to shift to more environmentally friendly composites using agricultural waste products; Alberta is rich in such sources of agricultural waste materials that could benefit the industry. My research program's long-term goal in composite materials focuses on better understanding the behaviour and production of primarily two-dimensional braided composite materials and minimizing their impact on the environment, as well as translating our related discoveries to industry. In the past 10 years, our group at the Multipurpose Composite Group, has 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, and will train at least 16 HQP, aims to address in the short term, the following challenges: 1. To develop a complete life cycle analysis for green braids that could be manufactured using Albertan agricultural waste. 2. To improve the quality of the manufacturing process and braided composite end product focusing on yarn twist. 3. To experimentally determining the behaviour of braided composites under complex and fatigue loading scenarios as well as thermal effects. 4. To develop new models, based on accurately measured geometry, to better predict mechanical properties including fatigue behaviour and weathering effects.

复合材料的生产和使用构成了数十亿美元的行业，由于其轻巧，高机械性能，环境抵抗力以及重要的能源和材料节省，彻底改变了许多领域（航空航天，汽车，生物医学，民用）。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在开发和使用先进的编织复合材料方面具有许多考虑因素和复杂性：制造质量，对复杂和疲劳负荷下的性质和行为的全面了解，并因此预测其性质。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的回报率较低或缓慢。但是，如果这些挑战在配备最先进的研究机构中成功解决，则编织可能会成为一系列董事会系列的高级制造业。它们的环境影响是辫子和其他复合材料的第二个更广泛的挑战。已经做出了许多努力，使用农业废品转移到更环保的复合材料上。艾伯塔省丰富了这样的农业废料来源，可以使该行业受益。 我的研究计划在复合材料中的长期目标重点是更好地了解主要是二维编织的复合材料的行为和生产，并最大程度地降低了对环境的影响，并将我们相关的发现转化为行业。在过去的10年中，我们在多功能复合材料组的小组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，并将培训至少16个HQP的NSERC DISCOVER GANT提案，目的是在短期内解决以下挑战：1。为可以使用艾伯塔省农业废物制造的绿色辫子进行完整的生命周期分析。 2。为了提高制造过程的质量和编织的复合终端产品，重点是纱线。 3。通过实验确定在复杂和疲劳载荷方案以及热效应下编织的复合材料的行为。 4。开发基于精确测得的几何形状的新模型，以更好地预测机械性能，包括疲劳行为和风化效果。
