项目摘要

The transportation industry is showing a strong interest in using high performance polymer composites to achieve weight reductions that can not be achieved with metals. However, the cycle times of the traditional composite manufacturing processes are not adapted to the production of parts in large series. Recently, the development of fast curing thermosetting resins has opened the door to the mass production of composite parts using variants of resin transfer moulding (RTM) and compression prepreg processes. Few works on the manufacture of composite parts for land transport (automobile, trucks, buses) were conducted with these fast resins in an industrial environment in Quebec and even in North America. The reactivity of these resins creates manufacturing and quality challenges for moulded parts, parts design and tooling. The existing process simulation tools must also be modified to take into account the dynamic behaviour of these resins and new physical models of these materials must be developed. This project aims to solve these manufacturing problems, to develop robust, fast and efficient processes for manufacturing high-performance composite parts, to develop tools to model and predict these manufacturing processes and to validate these solutions with the manufacture of a composite demonstrator relevant to the land transportation industry, in order to minimize the risks of adoption of these composite materials by the Quebec and Canadian industry.

运输行业对使用高性能聚合物复合材料来实现金属无法实现的减重表现出浓厚的兴趣。然而，传统复合材料制造工艺的周期时间不适合大批量零件的生产。最近，快速固化热固性树脂的开发为使用树脂传递模塑 (RTM) 和压缩预浸料工艺的变体大规模生产复合材料部件打开了大门。在魁北克甚至北美的工业环境中，很少有使用这些快速树脂制造陆地运输（汽车、卡车、公共汽车）复合材料零件的工作。这些树脂的反应性给模制零件、零件设计和模具带来了制造和质量挑战。还必须修改现有的工艺模拟工具，以考虑这些树脂的动态行为，并且必须开发这些材料的新物理模型。该项目旨在解决这些制造问题，开发稳健、快速和高效的工艺来制造高性能复合材料零件，开发对这些制造工艺进行建模和预测的工具，并通过制造与制造相关的复合材料演示器来验证这些解决方案。陆路运输行业，以尽量减少魁北克和加拿大工业采用这些复合材料的风险。
