  • Mould tool and method for resin transfer moulding
    Patent number: 7128857
    Abstract: A mould tool for use in resin transfer moulding operations is provided, the tool comprising one or more shape-defining portions which together define the shape of a component to be manufactured within the tool, and an inlet path for allowing resin to be injected into the mould tool. The mould tool further comprises at least one bleed cavity and a removable closure member, the closure member being capable of closing the bleed cavity and, in use, substantially sealing the bleed cavity to prevent fluid egress from the bleed cavity. A method of resin transfer moulding is also provided.
