Disclosed is an elastic shape-memory polymer composite skin having a zero Poisson's ratio. The elastic shape-memory polymer composite skin comprises: a body formed of conductive fibers; a plurality of metal frames that are disposed on a lower portion of the body and deliver electrical power to the body; and a plurality of reinforcement members that are coupled to the lower portion of the body so as to be spaced from the plurality of metal frames, wherein the body may change temperature on the basis of the electrical power delivered from the plurality of metal frames. Accordingly, low-power, long-duration flight in a morphing aircraft can be maintained due to low aerodynamic loss. Est divulgué, un revêtement composite polymère à mémoire de forme élastique ayant un coefficient de Poisson nul. Le revêtement composite polymère à mémoire de forme élastique comprend : un corps formé de fibres conductrices ; une pluralité de cadres métalliques qui sont disposés sur une partie inférieure du corps et fournissent de l'énergie électrique au corps ; et une pluralité d'éléments de renforcement qui sont accouplés à la partie inférieure du corps de façon à être espacés de la pluralité de cadres métalliques, le corps pouvant changer de température en fonction de l'énergie électrique fournie à partir de la pluralité de cadres métalliques. En conséquence, un vol à faible consommation énergétique et de longue durée dans un aéronef métamorphosable peut être maintenu en raison d'une faible perte aérodynamique. 제로 포아송 비를 갖는 신축성 형상기억 폴리머 복합재 스킨이 개시된다. 신축성 형상기억 폴리머 복합재 스킨은, 전도성 섬유로 이루어진 본체; 상기 본체의 하부에 배치되어, 상기 본체로 전력을 전달하는 복수의 금속 프레임; 및 상기 복수의 금속 프레임과 각각 간격을 두고 상기 본체의 하부에 결합되는 복수의 보강재를 포함하고, 상기 본체는 상기 복수의 금속 프레임으로부터 전달된 전력에 기초하여 온도가 변할 수 있다. 이에 따라, 공력 손실이 적어 모핑 항공기에서의 저전력 긴 비행 시간을 유지시킬 수 있다.
