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.

1.Fiberglass gating cover plate
The anti slip performance can be show out only in
fiberglass gating cover plate, such as grid sand covered and Striped grating. The appearance of Fiberglass gating cover plate can be smooth, nonslip paving sand surface is probably slip markings, cover plate thickness usually 4.0cm. It can also used according to Customer credentials size, which often use in a closed area for sewage disposal punishment measures and prevent gas spillover. Anti slide grating cover can also be used as a ramp, manhole cover and trench cover.
