Title:
ELASTIC SHAPE-MEMORY POLYMER COMPOSITE SKIN HAVING ZERO POISSON'S RATIO
Document Type and Number:
WIPO Patent Application WO/2021/261676
Kind Code:
A1
Abstract:
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.
