ABSTRACT:
An elongate flexible vacuum tube including an inner porous liner of intertwined flexible fibers of nylon or the like connectable between a vacuum source and the interior of a flexible vacuum bag covering a part formed of uncured thermosetting resin, or of superposed sections or laminae with thermosetting adhesive therebetween, under an overlying porous breather pad of intertwined fibers. An end of the liner can be positioned in intimate contact with the breather pad to form a vacuum path therewith so that a vacuum can be pulled on the part from a vacuum source, through the porous liner and breather pad, while it is being cured in an autoclave.
