摘要：

In order to improve the application of shape memory polymers in extreme harsh environments, the ultrathin carbon fibers reinforced polyether-ether-ketone (CF/PEEK) composite with 0.036 mm thickness was fabricated by overlapping and hot-pressing technologies, and the shape memory behaviors of the composite under the action of thermal stress were investigated. The results show the shape recovery rate of CF/PEEK composite ultrathin laminate is approximately 100%, and still has above 90% reversion rate after 100 times tests of thermal cycling action at 320℃. The stress-driving deformation mechanism of CF/PEEK composite is explained based on the relationship between temperature and stress-strain. The CF/PEEK composites with variable thickness were designed to simulate the deformation and recovery of complex shapes, containing deep-sea coral, cube and pitcher plant. Using mechanical clamping force during the deformation of CF/PEEK composite, the grasping coin experiment was carried out, which verifies the application feasibility for the active deformed structure of CF/PEEK composite. © 2021, Editorial Office of Acta Materiae Compositae Sinica.
