摘要： A composite shaft or rod formed by filament winding. The composite shaft is a solid shaft and the filament winding does not involve a mandrel. A filament core can be suspended between rotatable spindles and the filament materials can be laid directly onto the filament spindle, without any mandrel. A plurality of payout eyes can be used to simultaneously lay filament materials onto the filament core. A bridge plug can be formed with the solid composite shaft located within the bridge plug shell of the bridge plug.
