A composite article includes a first segment and a second segment spaced apart form the first segment. The composite article includes continuous fibers that extend from the first segment to the second segment. The composite article also includes discontinuous fiber distributed throughout the composite article.

Molded article and method for making the same

A modular fan assembly includes a center hub assembly and a first blade attached to the center hub assembly. The center hub assembly includes a first plate and a second plate each having an outer edge and a planar capture surface. The planar capture surfaces of the second plate is arranged parallel to the planar capture surface of the first plate. The first blade includes a mounting pad and a working portion. The mounting pad has opposite, parallel planar surfaces positioned in contact with the respective planar capture surfaces of the first and second plates. The working portion extends beyond the outer edges of the first and second plates. A thickness of the first blade is smaller proximate the outer edge of the first plate than at the mounting pad to create a first gap between the first blade and the first plate at the outer edge.

Modular fan assembly

A fan blade () includes a working region () having a leading edge () and a pressure side (). A plurality of flow modification features (-to-) are positioned at the working region, including first and second flow modification features (---) each having a wedge shape with a pointed end () and a wider end (), and located on the pressure side. A length of the first flow modification feature is less than a chord length of the fan blade, and the pointed end of the first flow modification feature is spaced from the leading edge. A length of the second flow modification feature is less than the chord length of the fan blade, and the pointed end of the second flow modification feature is spaced from the leading edge. The first and second flow modification features are spaced from each other to define a channel () therebetween.

Fan blade surface features

A method of making a modular fan includes positioning a mounting pad of a blade between two plates of a center hub assembly, aligning the blade such that the mounting pad is located radially inward of an outer edge of at least one of the two plates, and spacing the outer edge of the at least one of the two plates from the blade at the outer edge.

Composite fan and method of manufacture

A modular fan assembly includes a center hub assembly and a first blade attached to the center hub assembly. The center hub assembly includes a first plate having an outer edge, and a second plate having an outer edge. The first blade has a mounting pad and a working portion. The mounting pad is positioned in between the first plate and the second plate. The working portion extends beyond the outer edges of the first and second plates of the center hub assembly. A thickness of the first blade is smaller proximate the outer edge of the first plate than at the mounting pad to create a first gap between the first blade and the first plate at the outer edge of the first plate.

Composite fan

The invention provides a more durable composite fan assembly with a metal hub including a portion adapted for rotation and for engagement with a plastic body and including at least one peripheral portion offset from its plane of rotation, and a plastic body forming a plurality of air-moving blades molded in engagement with the offset peripheral portion of the metal hub. The offset peripheral portion of the metal hub can comprise a number of configurations, for example, it can comprise one or more annular portions formed adjacent the periphery of the hub, including but not limited to, a complete annulus offset from the plane of rotation of the hub periphery. The offset peripheral portion can also comprise one or more portions at the periphery of the metal hub, which are out of the plane of rotation, preferably so that at least two offset portions extend out of the plane of rotation at an acute angle of about 10.degree. to 30.degree. on one or both sides of their plane of rotation. The offset portion may be formed by a plurality of peripheral portions which are formed to provide a wavy peripheral portion of the metal hub, including, for example, a plurality of joined waffle-like peripheral segments that are alternatingly displaced in both directions from the plane of rotation of the peripheral portion of the central hub.
