摘要：The present invention relates to a method for forming a composite structure.The method includes arranging a stack (1) of prepreg sheets (2) on a mold (3). Thecomposite material is substantially sealed within a vacuum bag. One or more vacuumports extend through the vacuum bag. Vacuum is applied through the vacuum ports fordrawing air from the stack of prepreg sheets. Air (7) in the space between each twoprepreg sheets in the stack is evacuated through at least one less impregnated layer (4)within a least one of the two adjacent prepreg sheets. The less impregnated layer (4)communicates with the vaccum port. The process is repeated until the stack (1) comprisesa predetermined number of prepreg sheets (2). The composite material is cured and thestructure is released from the mold (3) and the vacuum bag.
