Zusammenfassung:A low-deflection roller tube of a motorized roller shade may have an outer diameter that does not exceed 2 inches. When a covering material is attached to the roller tube and the roller tube is supported at opposed ends thereof, deflection of a 10 foot configuration of the roller tube may not exceed ⅛ of an inch, and deflection of a 12 foot configuration of the roller tube may not exceed ¼ of an inch, relative to corresponding unloaded positions of the roller tubes. The roller tube may comprise a plurality of layers of carbon fiber, or may comprise an inner tube that is made of a first material, such as aluminum, and a carbon fiber outer tube that is formed on the inner tube. At least one layer, such as an outermost layer, may comprise high modulus carbon fiber.
