Abstract
A tube having enhanced inner diameter stiffness is provided. The tube includes a wall having an inner zone, intermediate zone, and an outer zone. The intermediate zone includes a plurality of partially offset and overlapped plies that form a number of non-radial spokes and voids extending from the inner zone and the outer zone. The non-radial spokes of the tube facilitate the transmission of torque from the inner zone to the outer zone during winding and handling operations, while insulating the inner diameter from radial pressure on the outer zone. The spokes and voids may essentially extend around the entire circumference and length of the tube and thus provide for more consistent properties throughout the tube.
