    摘要: An apparatus and method for sealing at least first and second cauls (60a, 60b) over a composite barrel part layup (50) on a mandrel (52), comprising:
    a first edge seal (62a) extending around a perimeter (76) of the first caul (60a) and configured to form a vacuum tight seal between the first caul (60a) and the mandrel (52); and
    a second edge seal (62b) extending around a perimeter (76) of the second caul (60b) and configured to form a vacuum tight seal between the second caul (60b) and the mandrel (52),
    wherein the first and second edge seals (62a, 62b) overlap and are configured to form a vacuum tight seal between the first and second cauls (60a, 60b).

    摘要: A method of manufacturing a portion of a shell of a wind turbine blade is disclosed. The method includes positioning a support member in an inner surface of a mould. The inner surface of the mould defines a profile of the portion of the shell. Further, a plurality of stacks of fiber is placed sequentially in the inner surface of the mould. Each of the plurality of stacks of fiber is secured to the support members by fastening member, and thereby eliminating the need for stitching the stack of fibres. The method further includes infusing resin through the plurality of stacks of fiber and allowing the resin to cure to obtain the portion of the shell of the wind turbine. The method of the present disclosure eliminates the conventional stitching process, thereby eliminating wrinkles that may be formed in the blade due to improper stitching.
