    Abstract:

    Air duct is a structure for adjusting the temperatureꎬ humidity and pressure inner the sealed cham ̄
    berꎬ which requires the air duct has good thermal insulating property and pressure tightness. The air duct had subsec ̄
    tion structureꎬ which made it difficult to ensure the dimension and pressure tightness. The air duct was made by auto ̄
    clave moldingꎬ which required high cost and long period. To solve the problemsꎬ the subsection structure of the air
    duct was improved to a whole structureꎬ so the air duct had better pressure tightness. Vacuum assisted resin infusion
    (VARI) was chosen instead of autoclave molding to manufacture the air duct. The results of mechanical properties of
    composite made by the two processing methods showed little differentꎬ which indicated that the mechanical properties
    can meet the requirements with VARI processingꎬ and the production cost and cycle can be reduced.
