Embodiment 1
[0045] In order to solve the problem that the expansion and curling process of the inflatable tube of the inflatable antenna is difficult to control, the present invention provides a shape memory inflatable tube structure, see figure 1 , figure 2 As shown, the shape memory inflatable tube structure includes a shell structure 1 and a pneumatic structure, wherein: the pneumatic structure is arranged inside the shell structure 1; the shell structure 1 includes a tube body 11 and at least one heating film 12; the heating film 12 is attached to the tube body 11 on the outer wall; the material of the tube body 11 is a shape memory composite material; the pneumatic structure includes a PET braided net tube 21 and a latex tube 22; the latex tube 22 is arranged inside the PET braided net tube 21.
[0046] Shape memory polymers have a specific initial shape, and after being deformed and fixed under certain conditions, they can restore their original shape through stimulation by externa...
Embodiment 2
[0054] On the basis of Example 1, in the shape-memory inflatable tube structure provided by this example, the shape-memory composite material includes epoxy-based shape-memory polymer and carbon fiber, wherein the role of epoxy-based shape-memory polymer is to control the tube body 11, the effect of carbon fiber is to enhance the strength of the pipe body 11.
[0055] The tube body 11 is made of epoxy-based shape memory polymer and carbon fiber, so that the shape of the tube body 11 is easy to control, and the strength of the tube body 11 can also be enhanced, and the surface tube body 11 is damaged, prolonging the use of the tube body 11 life.
[0056] The glass transition temperature of the shape memory polymer is related to the specific polymer type. The transition temperature of the epoxy-based shape memory polymer in this example is 120°C, and the glass transition temperature is suitable for the use environment of the air-filled antenna. , when the tube body 11 is not he...
Embodiment 3
[0060] On the basis of embodiment two, see image 3 As shown, the number of heating film 12 in this embodiment is one, and one heating film 12 is arranged at the middle position of the tube body 11 along the axial direction, and the length of the heating film 12 is shorter than the length of the tube body 11 .
[0061] Stick the heating film 12 on the middle section of the tube body 11 along the axial direction of the tube body 11, turn on the heating film 12 and turn on the power supply, the heating film 12 will heat the tube body 11, when the tube body 11 around the heating film 12 After the temperature rises to the glass transition temperature of the epoxy-based shape memory polymer, the tube body 11 is bent and shaped, and the tube body 11 changes from a straight shape to a U shape. After the power is turned off and the temperature is lowered, the tube body 11 maintains the U shape. shape, thereby reducing the volume of the inflatable tube and facilitating the transportati...
