PRESSURE BOTTLE MADE FROM COMPOSITE MATERIALS AND METHOD OF MANUFACTURE OF SUCH BOTTLES Russian patent published in 2001 - IPC

FIELD: high-pressure vessels. SUBSTANCE: proposed bottle has multilayer load-bearing shell made from intersecting unidirectional threads and polymer binder and inner protective polymer envelope. Besides that, bottle is provided with capillary porous member located between framework and envelope; this member is made in form of circular reticular cellular structure with tetrahedral cells between intersecting strips located at intervals in circular and axial directions. Bottle is also provided with at least one layer of anti-adhesive material laid between framework and capillary porous member. Method of manufacture of such bottle includes supply of excessive pressure to protective polymer envelope, winding intersecting unidirectional threads impregnated with polymer binder forming layers of load-bearing framework and heat treatment of bottle; prior to winding, capillary porous member is laid on protective layer and at least one layer of adhesive material is laid on it. EFFECT: enhanced reliability. 4 cl, 6 dwg
