The invention relates to a shape memory alloy fiber and super-elastic body compound deformation skin, belonging to the technical field of aviation, and aiming at solving the problems that the existing deformation skin has a single function and is poor in deformation performance. The shape memory alloy fiber and super-elastic body compound deformation skin comprises a super-elastic body base body and shape memory alloy fibers, wherein the shape memory alloy fibers are arranged in the super-elastic body base body in parallel in a curing way. The multifunctional deformation skin has in-plane deformation capability, out-plane deformation capability and variable rigidity characteristic, is capable of realizing the in-plane deformation with the shearing angle being +/-20 degrees and hardly has large wrinkles; the out-plane deformation can be transformed into a T-shaped curved surface state from a plane state. Furthermore, due to the excitation of heat energy, in the martensite phase and austenite phase transformation process of shape memory alloy, the compound skin system can obtain the variable rigidity characteristic.
