Abstract:
A fiber glass filament-wound porous tube for use in a reverse osmosis water purification system is made from multiple layers of resin impregnated continuous glass roving. These tubes are fabricated either by an open weave helical filament winding technique or by adding to the impregnating resin certain amounts of blowing agent having a decomposition temperature slightly below or above the resin cure temperature.
