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.

Fiberglass steps are crafted through a meticulous process that involves layering fiberglass strands over a sturdy core, typically made from composite materials or metal. This construction method ensures that each step can bear significant weight without bending or breaking, making them exceptionally reliable for high-traffic areas. The surface of these steps is often textured to provide a non-slip grip, ensuring the safety of those who use them, even in wet or icy conditions.
