To reach this goal, the team is working on different objectives such as material design, additive manufacturing (AM), numerical work to predict the mechanical and thermal behavior of the structures, induction welding to attach different parts of the lunar rover and finally assembly of different rover components. Our focus is on the additive manufacturing section of the project which aims to fabricate the sandwich panels with the desired cell distributions on a planar and non-planar surface to maintain the mechanical properties while lowering the overall rover weight.<\/span><\/p>\n<h2><span class=\"fontstyle3\"><br \/>\n<\/span><span class=\"fontstyle0\">The challenge<\/span><\/h2>\n<p><span class=\"fontstyle0\"><br \/>\n<\/span><span class=\"fontstyle3\">The harsh condition on the moon such as its temperature variation that can alter from more than 100 \u00b0C during the day to lower than -150 \u00b0C during nights which last for 14 days, requires systems that can tolerate and function in this temperature range. The body of the rover should be also sturdy enough to tolerate the weight of the components needed to be attached or carried during its cruising on the moon and also not to get damaged by the corrosive dust and sharp-edged rocks. One way to improve the mechanical properties of the rover structure is to add to the thickness of the body\u2019s structure or to build it with stronger materials. The usual approaches to improve the mechanical properties of the rover body will lead to the addition of mass which results to a heavier rover that consumes more energy for its functions. The advanced composites offer high mechanical performance and using AM techniques allows us to even lower the weight by decreasing the amount of material where the applied forces are lower. On the other hand, the printability of advanced polymers and composites are still challenging mainly due to their high melting point.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p class=\"link-btn-style btn-yellow\"><a href=\"https:\/\/cqfa.quebec\/en\/etude-de-cas_lm2-peekboot_ang-2\/\" target=\"_blank\" rel=\"noopener\">Read the case study<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Polytechnique Montr\u00e9al, \u00c9cole de technologie sup\u00e9rieure (\u00c9TS), Universit\u00e9 Laval, Agence spatiale canadienne (ASC), ArianeGroup, NanoXplore, Mekanic, Dyze Design (since 2018). &nbsp;
