description núcleos estruturais e painel compósito esta invenção refere-se a um núcleo estrutural compreendendo uma tela de reforço fibrosa não-tecido de nanotubos de carbono, sendo que a tela é revestida com uma resina termofixa ou termoplástica sendo que os nanotubos de carbono são orientados dentro da tela de reforço de forma que após o revestimento com resina, a razão de módulo no plano da tela em uma primeira direção em relação ao módulo em uma segunda direção ortogonal em relação à primeira direção é no máximo de 2.0; o módulo de young em plano da tela revestida com resina é pelo menos 14 gpa e a resina de revestimento compreende de 15 a 75 porcento em peso do peso de tela mais resina. This invention pertains to a structural core comprising a nonwoven fibrous reinforcement web of carbon nanotubes, the web being coated with a thermoset or thermoplastic resin wherein the carbon nanotubes are oriented within the reinforcement web such that, after resin coating, the ratio of modulus in the plane of the web in a first direction to the modulus in a second direction orthogonal to the first direction is no greater than 2.0; the in-plane Young's modulus of the resin coated web is at least 14 GPa and the coating resin comprises from 15 to 75 weight percent of the weight of web plus resin.
