Filament Wound Fiber Glass Wing Tank
Abstract
Ten filament wound glass reinforced plastic, sandwich-wall wing tanks were fabricated using a process amenable to low cost production. The tanks were 100-gallon capacity and designed to meet the Cessna A-7B wing tank geometry and loading excepting for internal pressure which was increased from 50 to 200 psig. The major problem experienced and solved during the program was the formation of a plastic liner. The liner also served as the winding mandrel which is the key to keeping the cost competitive with aluminum tanks. The feasibility of the filament wound tank was demonstrated with the successful fabrication of tanks that met all the structural and dimensional requirements. The process practicality was proven; however, the fabrication methods used during this program need to be further refined. Figure 1 shows the completed tank attached to the aircraft.
