Title (EN) UNITARY STRATIFIED COMPOSITE
(FR) COMPOSITE STRATIFIE UNITAIRE
Abstract:
(EN) A unitary stratified composite composed of a first stratum and a second stratum integrally connected by a transition zone is disclosed. The first stratum serves as a liquid acquisition stratum that rapidly acquires and then transfers liquid to the second stratum. The second stratum serves to withdraw liquid from the first stratum and further serves as a temporary storage stratum. Methods for forming the unitary stratified composite are also disclosed.
(FR) La présente invention concerne un composite stratifié unitaire se composant d'une première couche et d'une seconde couche entre lesquelles une zone de transition assure une liaison intégrale. La première couche sert de couche de captage de liquide capable de capter rapidement puis de transférer le liquide vers la seconde couche. La seconde couche, qui sert à purger de liquide la première couche, sert en outre de couche de stockage temporaire. L'invention concerne également un procédé de réalisation de ce composite stratifié unitaire.
