Abstract
A high efficiency belt having reduced bending stiffness while maintaining a high coefficient of friction. The belt includes a backing layer, a rib material layer, and cords embedded within, wherein the coefficient of friction of the high efficiency belt is greater than or equal to 0.03 mm/N times the bending stiffness for belts having a thickness in the range of from 2.6 mm to 4.2 mm. The belt can include a bending stiffness in the range of from about 30 N/mm to about 65 N/mm and an anisotropic modulus of elasticity ratio of between 1.1 and 5.0. Methods of manufacturing the high efficiency belt are also described and can include forming sheets of rib material with parallel aligned reinforcement fibers transverse to the direction of rotation of the high efficiency belt.
