LAMINATED PIPE Russian patent published in 2003 - IPC

FIELD: high-precision tubular rod articles for space and ground applications. SUBSTANCE: proposed laminated pipe consists of inner layer 1 formed by winding tapes of definite width made of unidirectional fiber material impregnated with polymeric binder. Said tapes are wound to spiral in two opposite directions at angle of α = 5÷89^° to pipe axis. Middle layer 2 is made up of interconnected elements of similar rectangular section laid one close to the other over pipe generatrix at angle of 0^o to pipe axis. Said elements are made of material identical to material of inner and outer layers or different from said material. Outer layer 3 is similar in structure to inner layer, being made of material identical to material of inner layer. EFFECT: provision of laminated pipe featuring high stability of shape and size at temperatures from minus 50 to plus 50 C. 3 cl, 2 dwg
