(EN) MICRO-SINTERED NODE EPTFE STRUCTURE
(FR) Structure EN ePTFE À nœuds micro-frittés
Abrégé
(EN)
The ePTFE structure includes an ePTFE structure which has a node and fibril micro- structure. The microstructure includes specific nodes, which are connected to the fibrils. One or more of the specific nodes are sintered and the fibrils are un-sintered. A method for making the ePTFE structure includes identifying and sintering one or more of the specific nodes.
(FR)
L'invention concerne une structure en ePTFE comprenant un nœud et une microstructure de fibrilles. La microstructure comprend des nœuds spécifiques qui sont reliés aux fibrilles. Un nœud spécifique ou plusieurs sont frittés et les fibrilles ne sont pas frittées. L'invention concerne également un procédé de fabrication de la structure en ePTFE consistant à identifier et à fritter un ou plusieurs nœuds spécifiques.
