The toroidal membrane diaphragm is desirable to be originally formed in a rotatory symmetric structure of composite rubber sheet from the view point of its strength and the working functions. Some trials for such a construction of diaphragm had been presented, but they could not have been in practical use because of their structural complexity. In this study, a quasi-isotropic diaphragm made of triaxially woven fabric was examined experimentally in the stroke properties and fatigue strength. Then, a non-linear analysis on the equilibrium shape and the wrinkling phenomenon of the pressurized membrane diaphragm was given. A good agreement between the theoretical and the experimental results was obtained.
