Patent number: 8734711Abstract: The present invention provides a method for producing a profile from composite fiber material, in particular in the aviation and aerospace field, having the following steps: A preliminary fabric, particularly made of pre-impregnated fiber material, is first packed in a vacuum bag. Then support elements are laid on the packed preliminary fabric to support the latter. The vacuum bag is then supplied with a vacuum. Next, the preliminary fabric is hardened to the profile under the action of heat, in particularly in an autoclave.

A discrete length of elastic substrate is positioned on the outer circumferential surface of the rotating drum, wherein the discrete length of elastic substrate is in a stretched state and defines a first length. The discrete length of elastic substrate may be defined by a first end region, a second end region, and a central region separating the first and second end regions. The method may comprise applying vacuum pressure to the first, second, and central regions of the discrete length of elastic substrate. Vacuum pressure may be reduced on the first and second end regions such that the discrete length of elastic substrate consolidates to a second length that is less than the first length.Type: ApplicationFiled: June 28, 2013Publication date: January 2, 2014Inventors: Mark Mason Hargett, Jeffrey Alan Darner
