A rim for a bicycle wheel includes a radially inner portion disposed along an inner circumference of the rim. The rim also includes a first sidewall, a second sidewall spaced apart from the first sidewall, and a radially outer tire engaging portion disposed along an outer circumference of the rim. The first sidewall, the second sidewall, the radially outer tire engaging portion, the radially inner portion, or any combination thereof includes a composite laminate. The composite laminate includes a layer of a composite material. The composite material includes a matrix of a polymer-based material and natural fibers of a reinforcing material. A volume of a respective one of the natural fibers of the layer of the composite material is greater before lamination of the composite laminate compared to the volume of the respective one natural fiber after the lamination of the composite laminate.

A method for producing an automobile rim made of aluminum or an aluminum alloy for a wheel of an automobile, the automobile rim having a rim well delimited on opposite sides by an outer flange and an inner flange, a hub with a center recess and a bolt hole circle as well as a rim center connecting the rim well and the hub with one another. The automobile rim is produced in one piece and continuously in a casting mold by die casting of a casting material. The automobile rim is formed during the die casting with at least one air conveying element for conveying air in the axial direction with respect to a longitudinal center axis of the automobile rim relative to an imaginary plane perpendicular to the longitudinal center axis and/or at least one surface enlargement element extending in the circumferential direction along a circular line.

The invention relates to a wheel rim for a vehicle wheel with cover elements.

A wheel structure for a vehicle includes: a rim, and a resonator including a plurality of resonance tubes attached along an outer peripheral surface of the rim. The plurality of resonance tubes are spaced apart from each other and connected along the outer peripheral surface of the rim by a plurality of strips, and an end of each of the strips is coupled to a corresponding end of each of the resonance tubes.

A composite PDU tire in an aircraft cargo handling system may comprise a plurality of bonded regions configured to propel cargo within an aircraft cargo bay. The composite tire may include edge regions that are stiffer than a cylindrical region. The edge regions may be configured to have a greater wear resistance and abrasion resistance relative to the cylindrical region. The cylindrical region may be configured to have greater traction relative to the edge regions. The edge regions may include a fillet profile and may be configured to reduce chipping as cargo climbs across the tire.

An aerodynamic bicycle rim comprising: a circumferential outer portion comprising a circumferential outer surface, the circumferential outer portion adapted to seat a bicycle tire; a nose; and a set of sidewalls, each sidewall extending radially from the nose of the aerodynamic bicycle rim to a corresponding transition to the circumferential outer surface to form a rim body having a maximum rim body width that is greater than a maximum width of the bicycle tire. The aerodynamic bicycle rim is operable to seat the bicycle tire so that the aerodynamic bicycle rim and the bicycle tire form an asymmetrical cross-sectional shape.
