A reusable vacuum bag apparatus for use in a compaction operation by which composite parts are formed. The apparatus includes a flexible, inflatable support structure which is secured to a reusable flexible mat vacuum bag. When inflated, the support structure maintains the vacuum bag in the orientation it needs to assume when placed on a forming tool associated with a compaction apparatus. The support structure is formed by a plurality of intercoupled linear and curving tubing segments which form a grid-like support structure. The support structure is shaped in accordance with the configuration and contours of the reusable vacuum bag portion, which is in turn shaped in accordance with a forming tool. The support structure can be de-inflated, which allows the vacuum bag secured thereto to be stored in a compact arrangement when not in use. The hollow tubular support structure also provides a very light support framework which is much more easily manipulated and handled by a lay-up mechanic when positioning the apparatus 10 on a forming tool.
