This project is motivated by significant demand for eco-friendly and recyclable composite structures for transportation systems in the automotive and aerospace industry, lightweight composite panels in the building industry, and spoolable composite piping for oil, gas and water applications. The objective of this partnership are to determine an application envelope for lightweight fiber reinforced thermoplastic composite structures based on their durability and thermomechanical performance under different environmental aging and long-term loading conditions. Lightweight continuous fiber-reinforced thermoplastic composites have received significant attention over the last decade due to their specific properties, such as excellent corrosion resistance, high strength-to-weight ratio, practically unlimited shelf-life of raw materials, recyclability and low cost. Significant reduction in manufacturing costs by using a rapid and continuous fabrication process, and the ability of thermoplastic matrix composites to be recycled with relative ease are two main advantages of using thermoplastic matrix materials in this project over their thermosetting counterparts. The project is in collaboration with an industrial partner: Composite Production Systems at Shawcor. The project outcomes will be (i) an application envelope for the thermomechanical performance of commercial thermoplastic-based reinforced composite structures providing details about the limitations and long-term performance of such structures; (ii) augmentation of recyclable composites in the portfolio of the industrial partner aiding in business growth and job creation in Canada; (iii) an exceptional training program driven by scientific discovery through research on material behavior under adverse environmental conditions that can transcend sectors; and (iv) effective technology and knowledge transfer through short-term placements and workshops with the partner. The project will have an impact on (a) protecting the environment by advancing the use of recyclable materials; (b) augmenting the understanding of failure mechanisms in structural materials driven by advancements in multi-scale testing; (c) innovation in design and manufacturing of made-in-Canada products for oil/gas, water, and other industries that employ identical or similar materials (e.g., automotive) leading to job creation and economic growth. Each of the outcomes and impacts are important for Canada.

该项目的激励是由对汽车和航空航天行业的运输系统的生态友好和可回收复合结构的巨大需求，建筑行业的轻量级复合面板以及用于石油，天然气和水应用的可剥离复合管道。该合作伙伴关系的目的是根据不同的环境老化和长期加载条件下的耐用性和热力学性能来确定轻质纤维增强热塑性复合结构的应用。在过去的十年中，轻巧的连续纤维增强热塑性复合材料由于其特定特性，例如出色的耐腐蚀性，高强度重量比例，实际上无限的原材料搁板寿命，可回收性和低成本。通过使用快速和连续的制造过程，制造成本的显着降低，以及热塑性基质复合材料相对轻松地回收的能力是在此项目中使用热塑性矩阵材料而不是热压对应物中使用热塑性矩阵材料的两个主要优点。该项目与肖科（Shawcor）的工业合作伙伴合作：综合生产系统。项目结果将是（i）基于商业热塑性增强复合结构的热机械性能的应用程序，该结构提供了有关此类结构的局限性和长期性能的详细信息； （ii）在协助加拿大业务增长和创造就业机会的工业合作伙伴的投资组合中增强可回收复合材料； （iii）通过对不利环境条件下的物质行为的研究驱动的一项杰出培训计划，该计划可能超越行业； （iv）通过与合作伙伴的短期安置和研讨会通过短期安置和讲习班的有效技术和知识转移。该项目将通过推进可回收材料的使用来影响（a）保护环境； （b）增强对多尺度测试进步驱动的结构材料中故障机制的理解； （c）在加拿大制造产品的设计和制造中，用于石油/天然气，水和其他采用相同或相似材料（例如汽车）的工业，从而导致就业创造和经济增长。每个结果和影响对加拿大都很重要。
