Title
(EN) BILAYER REINFORCEMENT STRUCTURES
(FR) STRUCTURES DE RENFORT BICOUCHES
Abstract
(EN)
A multi-layer composition to be located onto a substrate. The composition comprises a bi-layer construction, including a first layer and a second layer, the first layer having a high elastic modulus and tensile strength in comparison to the second layer. The second layer includes a blowing agent such that, when cured, the first layer is spaced away from the substrate. The compositions of the first layer and second layer are similar, thus enabling the reconstitution of scrap into usable material for forming another multi-layer reinforcement.
(FR)
L’invention concerne une composition multicouche destinée à être située sur un substrat. La composition comprend une construction bicouche, comprenant une première couche et une seconde couche, la première couche ayant un coefficient d'élasticité élevé et une grande résistance à la traction par rapport à la seconde couche. La seconde couche comprend un agent gonflant de sorte que, lorsqu'elle est durcie, la première couche soit espacée du substrat. Les compositions de la première couche et de la seconde couche sont similaires, ce qui permet la reconstitution de chutes en un matériau utilisable afin de former un autre renfort multicouche.
