ABSTRACT:
A power transmission wheel of the gear wheel sprocket wheel and pulley wheel type has hub portion or rim portion formed of a composite material of discontinuous fiber disposed in a plastic matrix where teeth are formed in one of the portions so as to define flank surfaces and where lateral side portion of fiber follow the contour of the surface so as to minimize in portions of fiber at ends the flank surfaces. A method for manufacturing a power transmission wheel by winding a strip of uncured material having embedded discontinuous lengths of fiber, and winding the strip in a volute fashion to form a preform having oppositely facing sides, and pressing the preform on one side and shaping the preform, and heating the preform to define a power transmission wheel.
