Described is a membrane comprising a microlayer polymeric composite having at least about 10 microlayers. The microlayers are each individually up to about 100 microns thick and alternate between at least one gas barrier material and at least one elastomeric material. The membrane can be formed into a pressurized bladder or cushioning device for many applications, including footwear and hydropneumatic accumulators.
L'invention concerne une membrane (28A-F, 124), comprenant un composite (30, 30A) polymère à microcouches qui possède au moins 10 microcouches. Ces microcouches (32, 34, 112, 114, 116) présentent chacune individuellement une épaisseur pouvant atteindre environ 100 microns, et sont disposées entre au moins un matériau de barrière et au moins un matériau élastomère. La membrane (28) peut être formée dans une poche sous pression ou dans un dispositif de capitonnage pour de nombreuses applications, notamment des articles chaussants et des accumulateurs hydropneumatiques.
