The invention discloses a composite material anti-side-rolling torsion bar and a forming process thereof, the composite material anti-side-rolling torsion bar comprises a torsion shaft and a torsion arm, the torsion shaft comprises a shaft tube and a metal joint, the metal joint is provided with a pin structure, and the pin structure is wrapped in the shaft tube; the torsion arm comprises a torsion arm main body and a metal insert, the torsion arm main body is made of a composite material, and the metal insert is an annular cylinder and is embedded in the torsion arm main body to form a through hole penetrating through the two end faces of the torsion arm; and the metal joint passes through the metal insert and is fixed with the metal insert in an inserting manner. The forming process comprises the steps that S1, the torsion shaft is prepared; s2, preparing a torsion arm; and S3, assembling and fixing. Through the arrangement of the pin structure, the connection reliability of the metal connector and the shaft tube is improved. The torsion arm body is made of composite materials, and the overall weight of the device is reduced. And the torsion shaft and the torsion arm are formed separately, so that the manufacturing efficiency and the manufacturing quality of the anti-side-rolling torsion bar are improved.
