Abstract: A two-stage photo/thermal curing acrylate-epoxy resin system was designed in this work. By adjusting the different mass ratios in the two stages, the influence on the mechanical properties and shape memory properties of the resin system was explored. The optimized acrylate-epoxy resin system is used to prepare composite materials with aramid fibers. By adjusting the resin-fiber content ratio, the mechanical properties and shape memory properties of the composites are studied and optimized. Further, an inflatable deployable tube is fabricated using composite materials. The experimental results show that the inflatable deployable tube prepared by combining the photo/thermal two-stage curing technology can be designed into different permanent shapes as required, and by combining the inflatable deployment technology and the shape memory effect of the material, reversible control between the permanent shape and the new temporary shape can be achieved. In addition, the influence of the length-to-diameter ratio of the deployable tube on its pressure retention performance, mechanical properties and shape memory properties is analyzed in detail, and the theoretical analysis of the controllability of its shape is carried out.
