Different types of backing board materials were tested by internal explosion techniques to examine the feasibility of duplicating gunfire damage. Pressure deflection tests on a simulated airframe installation were ado to relate mechanical properties of the backing boards to their support characteristics for both self-sealing and bladder type fuel cells. Empirical equations were developed for the deflection of backing boards under fluid pressures. The tests included encountered the maximum and minimum spans which would normally be in aircraft structures. Equations were correlated with the physical properties of the backing boards as the basis for establishing a method of specifying backing boards. Production trials of USV CR 88 backing board were made to examine the feasibility of production by continuous methods and furnish material to the WADC.
