Design of polymer-based composites with enhanced mechanical properties for the 3D printing of aerospace interior components

可被具有相似力学性能但质量更低的聚合物基复合材料所取代。哈金森航空航天工业有限公司是一家为汽车和航空航天工业提供智能解决方案的公司，其目标是在其位于蒙特利尔的研究设施中使用熔融沉积建模（FDM）开发用于飞机内饰板的复杂形状支架的3D打印。增材制造或3D打印可以在不需要任何类型工具的情况下制造复杂的几何形状，大大降低了中小批量生产的制造成本。该公司表示非常有兴趣继续与LM2合作，进一步开发3d打印聚酰胺复合支架。在为期六个月的Engage Plus项目中，研究助理（RA） Linus Lehnert将继续与哈金森密切合作，进一步开发并创造新的复合配方，以满足工业合作伙伴的必要要求。具体的项目目标是：(1)设计一种新的复合材料配方，以增强聚酰胺（PA）基体的机械性能，同时满足航空航天要求；(2)使开发的复合材料能够进行3D打印；(3)执行材料表征以定义最佳制造参数；(4)制造3D打印支架并评估其性能。(5)概述并制定详细的工作计划，以建立哈金森和LM2之间关于航空航天应用增材制造的长期研究项目。在这个Engage Plus项目中，将制造含有玻璃纤维增强的PA基复合材料，并在FDM 3D打印系统上打印内部硬件。此次合作的成果必将有助于哈金森开发适用于飞机内饰板的轻型3D打印支架，这将有助于哈金森进入航空零部件3D打印市场。

could be replaced by polymer-based composites with similar mechanical properties but lower mass.Hutchinson Aerospace & Industry Ltd, a company providing smart solutions for the automotive and aerospaceindustry, aims to develop the 3D printing of complex-shaped brackets for aircraft interior panels using fuseddeposition modeling (FDM) in their research facility located in Montreal.Additive manufacturing, or 3D printing, enables the fabrication of complex geometries without the need forany type of tooling, significantly lowering the fabrication cost for low to medium volume production. Thecompany has expressed great interest in the continuation of the collaboration with LM2 to further develop 3Dprintable polyamide-based composite brackets. During a six-month Engage Plus project, a research associate(RA), Linus Lehnert, will continue to work in close collaboration with Hutchinson to further develop, as wellas create new composite formulations that meet the necessary requirements of the industrial partner.The specific project objectives are to (1) design a new composite formulations to enhance the mechanicalproperties of polyamide (PA) matrix while meeting aerospace requirements, (2) enable the 3D printing of thedeveloped composite, (3) perform material characterization to define optimal manufacturing parameters, (4)fabricate 3D printed brackets and evaluate their performance, and (5) outline and create a detailed work plan tosetup a long-term research project regarding additive manufacturing for aerospace applications betweenHutchinson and LM2. During this Engage Plus project, PA based composites containing glass-fiberreinforcements will be fabricated and interior hardware will be printed on an FDM 3D printing system. Theoutcomes of this collaboration will certainly contribute to the development of lightweight 3D printable bracketsuseful for airplane interior panels by Hutchinson, which will help the company to enter the market of 3Dprinting of aerospace parts.
