Abstract

An apparatus and method for fabricating a composite structure are described. A vacuum film (76) covers the structure (68), and a sealing element (40) having a compressible body and an adhesive outer layer of different material to compressible body is placed between the vacuum film (76) and an opposed surface to create a substantially sealed volume (78) containing the structure. A vacuum means is used to withdraw air from the substantially sealed volume (78) to compress the sealing element and create a substantially airtight seal between the vacuum film and the opposed surface.
