Advanced manufacturing of composites for structural and acoustic applications

增材制造（AM）在制造具有定制特性的廉价、高度定制的热塑性复合材料方面显示出无限的潜力。聚合物复合材料的轻质和高比刚度和强度与AM的灵活制造能力相结合，为需要高承载能力和精确控制结构几何形状的应用提供了独特的机会。这个大型项目主要涉及使用AM工艺制造用于结构和声学应用的复合材料。在这个项目中，我们建议（O1）开发用于熔融沉积成型（FDM）工艺的高性能材料，（O2）开发分析工具来预测FDM打印材料的机械行为，（O3）开发一种先进的FDM工艺，用于制造具有高机械强度和声学性能以及灵活制造性的高性能结构复合材料，（O4）发展一种先进的AM方法，用于在具有复杂表面的复合材料上直接沉积可磨损材料。此外，该项目还将继续（补充目标，SO1）为树脂传递模塑（RTM）制造的复合材料开发模拟工具和模型，这是NSERC与Safran S.A.（法国）。这个多学科项目将是蒙特利尔理工学院多元化学术研究团队与工业合作伙伴赛峰集团之间的合作。这个为期五年的研究项目是一个独特的机会，培训了几个高素质的人员（HQP），主要包括研究生（7个博士和5个硕士）和6个博士后研究员在多学科环境和非常专业的领域。该项目将提供实验工作和理论建模之间的平衡培训，并将在复合材料，先进制造和声学材料等各个领域产生重要的知识进步。该项目与加拿大和魁北克政府支持的更安全的公共交通和环境友好的“更绿色”飞机的发展直接相关。

Additive manufacturing (AM) has shown boundless potential for the manufacturing of inexpensive, highly-customized thermoplastic composites with tailored properties. The lightweight and high specific stiffness and strength of polymer composites combined with the flexible manufacturability of AM offers a unique opportunity for applications that require high load-bearing capacities and precise control over structure geometry. This large project mainly involves the manufacturing of composites using AM processes for structural and acoustic applications. In this project, we propose to (O1) develop high performance materials to be used in the fused deposition modeling (FDM) process, (O2) develop analytical tools to predict mechanical behavior of the FDM printed materials, (O3) develop an advanced FDM process for manufacturing of high performance structural composites featuring high mechanical strength and acoustic properties, and flexible manufacturability, and (O4) develop an advanced AM approach for the direct deposition of abradable materials on composites with complex surfaces. In addition, the project will pursue (supplementary objective, SO1) the development of simulation tools and models for the composites manufactured by resin transfer molding (RTM), which is a continuation of an NSERC Industrial Chair with Safran S.A. (France). This multidisciplinary project will be a collaboration between a diversified academic research team at Polytechnique Montreal and the industrial partner, Safran S.A. This five-year research project is a unique opportunity for the training of several highly qualified personnel (HQP) consisting principally of graduate students (7 PhD and 5 MS) and 6 postdoctoral fellows in a multidisciplinary environment and very specialized areas. The project will provide a balanced training between experimental work and theoretical modeling and will generate important knowledge advancements in various fields including composites, advanced manufacturing, and acoustic materials. This project is directly related to the development of safer public transportation and environmentally friendly "greener" airplanes supported by the Canadian and Quebec governments.
