摘要：A method for manufacturing a bicycle wheel rim includes: (a) providing a first mold assembly which includes an inner mold and an outer mold, the outer mold having an annular first forming face to surround an annular second forming face of the inner mold; (b) disposing annularly a first prepreg preform that overlie annularly and respectively the annular first and second forming faces; (c) causing the first and second forming faces to press the concaved faces and thermoforming the first prepreg preform to obtain an annular outer rim part; (d) forming a second prepreg preform into an annular inner rim part; and (e) combining the annular outer rim part with the annular inner rim part to form a wheel rim.
