At least one artificial fiber muscle groups are folded with one end of each scissor connector, in each scissor connector
The other end is folded with deployable component, and deployable component is to be hinged to form by multiple single-pieces.
The preparation process of artificial fibrillar muscle of the invention is as follows：Carbon nanometer paper is wrapped on nylon fiber, is made heterogeneous
Property nylon fiber, by heterogeneous nylon fiber wrapping coiled fibrillar muscle on mandrel (pole), at 140~160 DEG C
Under made annealing treatment, extract out mandrel, this winding after helicoidal structure be artificial fiber muscle.
Artificial fiber muscle of the present invention uses cheap high-strength nylon fiber, easily can be wound by twisting with the fingers
To change the performance of itself, there is provided quick, scalable, non-hysteresis, the stretching of long-life and torsion muscle, use setline and seam
The cheap high-strength polymer fiber of line of threading reduces production cost, while its is in light weight.
Deployable structure of the invention based on artificial fiber muscle can greatly reduce according to the contractility of artificial-muscle
The volume of deployable structure, it can reach more than 60% expansion deformation.Relative to memorial alloy, pneumatic muscles, electroluminescent contraction
Polymer, it is not necessary to complicated control system, and can greatly improve the expansion degree of deployed configuration.
