Abstract

A composite rim is provided, including: an annular body extending around a center, an imaginary annular line being defined on an outer surface of the annular body, the imaginary annular line extending around the center; and at least one composite fiber strip, spirally disposed around the imaginary annular line for at least 360 degrees and attached to the outer surface of the annular body, opposing ends of each of the at least one composite fiber strip in a longitudinal direction of the at least one composite fiber strip being aligned with the imaginary annular line.

Claims (12)

1. A composite rim, including:

an annular body extending around a center, an imaginary annular line being defined on an outer surface of the annular body, the imaginary annular line extending around the center; and

at least one composite fiber strip, spirally disposed around the imaginary annular line for at least 360 degrees and attached to the outer surface of the annular body, opposing ends of each of the at least one composite fiber strip in a longitudinal direction of the at least one composite fiber strip being aligned with the imaginary annular line.

2. The composite rim of claim 1 , wherein the at least one composite fiber strip includes a plurality of composite fiber strips, and at least two of the plurality of composite fiber strips spiral in different angles.

3. The composite rim of claim 2 , wherein the at least two of the plurality of composite fiber strips spiral in opposing directions.

4. The composite rim of claim 3 , wherein the at least two of the plurality of composite fiber strips are at least partially overlapped with each other.

5. The composite rim of claim 4 , wherein the at least two of the plurality of composite fiber strips are perpendicular to each other; one of the opposing ends of one of the plurality of composite fiber strips is located between the opposing ends of another one of the plurality of composite fiber strips; the opposing ends of each of the at least one composite fiber strip are not overlapped with each other on the imaginary annular line.

6. The composite rim of claim 1 , wherein the at least one composite fiber strip includes a plurality of composite fiber strips, and one of the opposing ends of one of the plurality of composite fiber strips is located between the opposing ends of another one of the plurality of composite fiber strips.

7. The composite rim of claim 1 , wherein the opposing ends of each of the at least one composite fiber strip are not overlapped with each other on the imaginary annular line.

8. The composite rim of claim 1 , wherein the annular body includes a tire installation groove, and the imaginary annular line extends within the tire installation groove.

9. The composite rim of claim 8 , wherein the at least one composite fiber strip is conformably adhered to a surface of the tire installation groove.

10. The composite rim of claim 8 , wherein the annular body further includes two annular lips, and the two annular lips project toward each other from two peripheries of the tire installation groove.
