Another advantage of fiberglass is its flexibility. Unlike rigid materials like concrete, fiberglass can be molded into various shapes and sizes to fit the specific needs of a sewage treatment facility Unlike rigid materials like concrete, fiberglass can be molded into various shapes and sizes to fit the specific needs of a sewage treatment facility Unlike rigid materials like concrete, fiberglass can be molded into various shapes and sizes to fit the specific needs of a sewage treatment facility Unlike rigid materials like concrete, fiberglass can be molded into various shapes and sizes to fit the specific needs of a sewage treatment facilitysewage treatment fiberglass. This allows engineers to design custom-made structures that optimize the treatment process while minimizing space requirements. Additionally, fiberglass is easy to install and maintain, which helps reduce operational costs for sewage treatment facilities.

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.
