Abstract
A device for tensioning a preform made from interlaced fibers is applied to tension the preform used in a process for fabricating a part made from a ceramic matrix composite material. During this process, the preform is tensioned before and during its densification using the tensioning device (), which comprises a main body (), a first assembly element () and a second assembly element () and a control rod, rotation of the control rod causing translation of the second assembly element, separation of the first and second assembly elements from each other and tensioning of the preform along the longitudinal direction.
