The invention relates to a composite material that has improved properties as compared with known materials. The problems associated with known materials are that cell-free biomaterials have to be first populated with cells, lack of biocompatibility due to a composition that cannot be exactly reproduced and purity or a only minimal influenceability of resorption times. The composite according to the invention comprises a first unsupported layer having a first material that is insoluble, resorbable and non-gelling under physiological conditions; and a second layer, produced based on a cross-linked, gelatinous second material, said second layer having a mainly open-pore structure.
L'objectif de l'invention est de produire un matériau composite présentant des propriétés améliorées, dans lequel les inconvénients connus de la technique antérieure doivent être évités, tels que la nécessité de coloniser des biomatériaux exempts de cellules par des cellules, le manque de biocompatibilité, provoqué par une composition ne pouvant pas être reproduite exactement, et de pureté ou de l'influence minimale du temps de résorption. A cet effet, le matériau composite comprend une première couche autoportante fabriquée dans un premier matériau insoluble, résorbable, et non gélifiant dans des conditions physiologiques; et une seconde couche fabriquée dans un second matériau réticulé et gélatineux, la seconde couche présentant une structure principalement à pores ouverts.
