Japanese Patent JPS58502048
Kind Code:
A
Abstract:
A filament wound vessel (90) which includes at least one layer of resin impregnated glass fiber rovings (28) formed into bands (34), and hoop wound upon a rotating mandrel (10) in a direction approximately 90 to the longitudinal axis of the mandrel. The rovings are thus orientated at approximately 90 to the vessel axis. Next, at least one layer of weft unidirectional fabric (46) comprising strands of glass fibers woven with a suitable thread in the warp direction into a relatively wide band, is hoop wound upon the first hoop wound roving layer with a resin binder. This results in the woven glass fibers being orientated along the longitudinal axis of the vessel at approximately 0. Preferably the wide bands are wound in an overlapping manner (47, 48, 50) as in roof shingles wherein one and preferably two applied layers overlap the first applied layer. Next, at least one band (54) of resin coated or impregnated rovins is helically wound at an angle of from about + 40 to about +60, or -40 to about -60 to the longitudinal axis of the vessel (counterclockwise rotation being positive). Preferably, at least one additional band (58) of resin coated or impregnated rovings is helically wound in a direction opposite to the first helically wound band. Preferably, at least one layer of weft unidirectional fabric (70), woven with a suitable thread in a warp direction is hoop wound with the glass strands extending along the longitudinal axis of the vessel upon the helically wound bands of rovings. Preferably at least one additional band of resin coated or impregnated rovings (80) are hoop wound in a direction approximately 90 to the longitudinal axis of the vessel.
