The present application relates to the technical field of composite materials, and particularly relates to a
composite material oil tank and a forming method thereof. The present application provides a
composite material oil tank, which comprises a plurality of
barrel bodies with open ends, and the
barrel bodies are connected in the axial direction; the cross section of the first end of each
barrel body is a ladder structure with two ladder shapes which are symmetrical along the axis; the cross section of the second end of each barrel body is a protrusion structure with two protrusion shapes which are symmetrical along the axis and extend in the axial direction; the ladder structure and the protrusion structure are matched in shape to complete splicing; the surface of the protrusion structure close to the axis and one surface of the ladder structure are sealed and bonded by sealing glue; and the protrusion surface of the protrusion structure perpendicular to the axis and the ladder structure are bonded by structural glue. The present application provides a
composite material oil tank and a forming method thereof, which can realize the forming of a large-size and lightweight composite material oil tank and improve the sealing reliability of the composite material manufacturing.
