    • Description

    Vacuum Bagging Bleeder Cloths, used for Aircraft composites manufacturing

    Vacuum Bagging Bleeder Cloths, make of PTFE coated fiberglass fabric with low level of PTFE content, which has a higher porosity than normal PTFE coated fabric. In this case, air and extra resin will be allowed for passing through the bleeder cloths. This fabric is used as release sheet and bleeder cloth, for the manufacturing of aircraft composites, including satcom and weather radomes, helicopter rotor blade, structural components like wings, tail section, fuselage component and so on.

    Vacuum bagging stem is consist of vacuum bag, ventilated felt, cover, isolating membrane, bleeder, bleeder cloth(Porous PTFE fabric), composite, PTFE adhesive fabric and molding.

    After extracting vacuum, autoclave molding will release high temperature, high pressure by adding heat compression air, for the curing and molding of the composite. And KingRay PTFE coated fabric will provide a easy and clean release after curing process, air, resin and volatile will be allowed for escaping.

    The surface of composite will be excellent smooth by using Vacuum bagging bleeder cloths, and composite will be very easy to peeled off from the PTFE peel ply after cured.

     

    Property of PTFE coated Peel Ply

      Easy release and non stick.

    Composite will be easy and clean released from bleeder cloths.

      Allowing air, resin and volatile escaping during curing

    PTFE Peel Ply has a higher porosity than normal PTFE coated fabric, which can allow air, resin and volatile pass through in the curing process.

      Create super smooth surface for composite

    After release, the composite will have a excellent smooth and shiny surface, such as bonnet of automotive.

      Strong mechanical strength

    Vacuum bagging bleeder cloths has high tensile strength, which can resist the high pressure in autoclave. And cloth will not be tore when releasing the peel ply.

    In these applications, the release property, mechanical strength and porosity of Vacuum bagging bleeder cloths is critical to the manufacturing process and the quality of the composites.
