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.

增材制造（AM）表现出无限的潜力，用于制造具有量身定制特性的廉价，高度燃料的热塑性复合材料。聚合物复合材料的轻巧且高的刚度和强度结合了AM的柔性生产性，为需要高负载能力和对结构几何形状的精确控制的应用提供了独特的机会。这个大型项目主要涉及使用AM过程制造复合材料，用于结构和声学应用。在这个项目中，我们建议（O1）开发高性能材料，用于融合沉积建模（FDM）过程，（O2）开发分析工具，以预测FDM印刷材料的机械行为，（O3）开发出高级FDM的工艺，用于制造高性能的高性能结构材料，具有高性能的结构材料，并具有高度的机械强度和柔和的An An An An An An An Ane Ane Ane Ane Ane Ane Ane Ane Ane Ane Ane Ane Antiontries and Ans Antiont（O4）（O4）（O4）（O4）（O4）（O4）（O4）（O4）（O4）（O4）（O4）（O4）（O4）（O4）（O4）（O4）（O4）（O4）（O4）在具有复杂表面的复合材料上。此外，该项目将追求（补充目标，SO1）开发由树脂转移成型（RTM）制造的复合材料的模拟工具和模型，这是Safran S.A.（法国）Nserc工业椅子的延续。这个多学科项目将是蒙特利尔Polytechnique多元化学术研究团队与工业合作伙伴Safran S.A.之间的合作。这项为期五年的研究项目是培训几个高素质人员（HQP）的独特机会，主要由研究生（7 phd and 5 MS）（7 phd and 5 MS）和6个学科领域组成的多个学科和非常专业的环境。该项目将在实验工作和理论建模之间提供平衡的培训，并将在包括复合材料，高级制造和声学材料在内的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保“绿色”飞机的发展直接相关。
