A device for obtaining off-axis reinforcement of a woven object (10) is made up of a fixed mandrel (20) and a rotating mandrel (22). The rotating mandrel (22) is connected to the fixed mandrel (20) by shaft that rotates through the middle of the fixed mandrel (22). The shaft allows the rotating mandrel (22) to move up and down in relation to the fixed mandrel (20). A portion of the woven object (10) can be clamped to the fixed mandrel (20) while a second portion of the woven object (10) can be clamped to the rotating mandrel (22). When rotated, the rotating mandrel (22) causes the warp fibers (12) in the woven object (l0) to twist off the 0 < DEG > direction while fill or hoop fibers (14) remain substantially parallel to the 90 DEG direction.
