Design and advanced manufacturing of a lunar rover using thermoplastic composites

月球探测再次成为航天机构的高度兴趣。就加拿大航天局而言，其努力的方向是为月球轨道站和月球车研制机械臂。我们项目的主要目标是通过一个由10名研究人员组成的学术研究团队的合作项目，设计和制造一辆轻型月球车，这些研究人员来自三个机构（Polytechnique montracei， École de Technologie supsamrieure （ÉTS）和拉瓦尔大学），CSA和三个工业合作伙伴（ArianeGroup， NanoXplore和MËKANIC）。为了达到这个目标，团队将：（O1）设计满足空间环境要求（如高温、耐辐射、低放气）的热塑性复合材料；（O2）利用（O1）开发的材料，采用增材制造或拉挤工艺制造漫游车部件；（O3）采用感应焊组装各种复合材料部件；（O4）建立数值模型来预测复合材料和月球车结构的性能；（O5）整合不同的系统来获得一个功能性的月球车原型。这项工作是CSA发起的另一个项目的延续，该项目由CREPEC（愿景计划）资助，为期三年。该研究项目提出了创新的材料配方、制造和组装解决方案，以显着降低结构的重量、成本和制造时间，同时提高产品在极端条件下的耐久性。这一雄心勃勃的项目的实现将表明空间部门和一般运输方面的重大技术突破，并将成为加拿大魁北克和国际上加拿大空间方案的独特展示。该项目将提供实验工作和数值模拟之间的平衡训练，并将在热塑性复合材料，增材制造，空间级配材料等各个领域产生重要的知识进步。

Lunar exploration has again become of high interest for space agencies. In the case of the Canadian Space Agency (CSA), efforts are directed towards the development of a robotic arm for a lunar orbital station and a lunar rover. The main objective of our project is to design and manufacture a lightweight lunar rover through a collaborative project between an academic research team of ten researchers, from three institutions (Polytechnique Montréal, École de Technologie Supérieure (ÉTS) and Université Laval), CSA and three industrial partners (ArianeGroup, NanoXplore and MËKANIC). To reach this objective, the team will: (O1) design thermoplastic composite materials that meet the requirements of the space environment (e.g., high temperature, resistance to radiation, low outgassing), (O2) manufacture the rover components by additive manufacturing or pultrusion process using the materials developed in (O1), (O3) assemble the various composites components by induction welding, (O4) develop numerical models to predict the properties of composites and of the lunar rover structures and (O5) integrate the different systems to obtain a functional rover prototype. This work is the continuation of another project initiated by the CSA and funded by the CREPEC (Vision program) for three years. This research project proposes innovative material formulations, manufacturing and assembly solutions to significantly reduce the weight, cost and the manufacturing time of structures while improving product durability under extreme conditions. The realization of this ambitious project will point to a major technological breakthrough in the space sector and transportation in general and will be a unique showcase of the Canadian space program in Quebec, Canada and internationally. This project will provide a balanced training between experimental works and numerical modeling and will generate important knowledge advancements in various fields including thermoplastic composites, additive manufacturing, space-graded materials, etc.
