Filtration structure, in particular a particulate filter for exhaust gases of an internal combustion engine and a reinforcement element intended for such a structure

摘要

The invention relates to a filtration structure ( 11 ) consisting of: first and second filtration elements ( 15 A, 15 B) which comprise respectively a first face and a second face ( 24 A, 24 B), said faces being disposed opposite one another; and a connecting joint ( 17 ) which extends between the faces ( 24 A, 24 B) and connects same. The aforementioned joint ( 17 ) comprises a binder ( 41 ) and reinforcing means ( 43 ) which are embedded therein. The reinforcing means ( 43 ) comprise an open-work reinforcing member having an autonomous coherence and comprising an essentially-flat active part ( 45 ). The invention is suitable for particle filters for the exhaust gases from an internal combustion engine.
