[[Storage tank]]s can be made of fiberglass with capacities up to about 300 [[tonne]]s. Smaller tanks can be made with chopped strand mat cast over a thermoplastic inner tank which acts as a [[Optical fiber#Preform|preform]] during construction. Much more reliable tanks are made using woven mat or filament wound fiber, with the fiber orientation at right angles to the [[hoop stress]] imposed in the sidewall by the contents. Such tanks tend to be used for chemical storage because the plastic liner (often [[polypropylene]]) is resistant to a wide range of corrosive chemicals. Fiberglass is also used for [[septic tank]]s. |
