Abstract
A pressure vessel includes a first (base or innermost) layer composed of a resin-impregnated woven sleeve with chopped basalt fibers assembled in the voids of the sleeve and impregnated with an epoxy resin. A second and third layer is composed of continuous basalt fiber filaments arranged in a helical pattern, with the helical angle of the second layer being not equal to that of the third layer. A fourth layer is composed of continuous basalt fibers arranged in a hoop pattern. The fifth (outermost) layer is composed of randomly oriented chopped basalt fibers impregnated with a resin matrix and compacted with the subsequent wound filaments at up to ten pounds of tension.
