Abstract

Weight reduction is a major key to energy conservation. To achieve this goal, a composite material has been designed and topology optimization has been done to estimate the optimal topology of the climbing robot maintaining the minimum weight.  Epoxy matrix containing carbon nanofibers with contents of 0, 0.2, 0.4, 0.6 and 0.8 wt. % (EPC0, EPC0.2, EPC0.4, EPC0.6, EPC 0.6, and EPC0.8) have been firstly fabricated and mechanically tested. Epoxy-glass fibers composites with different layers numbers have been fabricated using lay-up technique as the second group of materials and tested. Epoxy-carbon fiber composite material (2-layers) has been fabricated and tested. The results revealed that epoxy-carbon fiber composite showed the best mechanical performance and the lowest weight concurrently. The results proved that using epoxy-carbon fiber composite as a structural material for the climbing robot could decrease the weight by 42.3% when compared with the aluminum frame. Topology optimization technique could offer an additional weight reduction of the robot frame by 29.3%.
