Abstract:

The use of high-modulus, low-density fibers is of particular interest in two areas of pressure vessel design. Firstly, weight reduction permits improved portability of large caliber guns. Secondly, high modulus wrapping is one of the few remaining options for increasing the working pressures in Ultra-High Pressure assemblies wherein working pressure and yield strength have similar values. The purpose of this work is to examine, using numerical models, various design and manufacture options for introducing residual stresses into a composite-wrapped tube and for minimizing damaging cyclic stresses during subsequent pressurization.
