Due to the hard carbon nanofibers and abundant welded joints among the nanofibers, the hard carbon aerogels display robust and stable mechanical performances, including super-elasticity, high strength, extremely fast recovery speed (860 mm s-1) and low energy loss coefficient (<0.16). After tested under 50 % strain for 104 cycles, the carbon aerogel shows only 2 % plastic deformation, and retained 93 % original stress.
Operators require proper training and protective gear, including earplugs, safety glasses, and steel-toed boots, due to the loud noise and potential hazards associated with the tool's operation Operators require proper training and protective gear, including earplugs, safety glasses, and steel-toed boots, due to the loud noise and potential hazards associated with the tool's operationcompressed air jack hammer. Regular maintenance is essential to ensure the equipment remains in optimal condition and to prevent accidents.
