In recent decades, carbon aerogels have been widely explored by using graphitic carbons and soft carbons, which show advantages in superelasticity. These elastic aerogels usually have delicate microstructures with good fatigue resistance but ultralow strength. Hard carbons show great advantages in mechanical strength and structural stability due to the sp3 C-induced turbostratic “house-of-cards” structure. However, the stiffness and fragility clearly get in the way of achieving superelasticity with hard carbons. Up to now, it is still a challenge to fabricate superelastic hard carbon-based aerogels.

The primary reason for the widespread adoption of FRP chimneys lies in their resistance to corrosion. Unlike metal chimneys that can corrode over time, especially when exposed to acidic or alkaline substances, FRP chimneys maintain their structural integrity even under harsh chemical environments. This makes them ideal for industries dealing with chemicals, power plants, refineries, and waste treatment facilities where corrosive gases are emitted.
