Popis: It has been found that PLA/PEEK blends have excellent mechanical properties and shape memory properties. In this article, the properties of PLA/PEEK blends were further studied. The mechanical properties of PLA/PEEK blends may be directly or indirectly affected by the molding temperature, molding method and heat treatment conditions. In this paper, PLA/PEEK blends were prepared under different processing conditions (molding temperature, molding method and heat treatment conditions) to evaluate the effects of different processing conditions on the mechanical properties of PLA/PEEK blends. In order to determine the lifting force of PLA/PEEK blends under different conditions, the effects of blends proportion and deformation temperature on the deformation force during the shape memory process were investigated. The experimental results show that the mechanical properties of PLA/PEEK blends can be improved by controlling the preparation conditions, and the deformation time and force can be effectively controlled by the proportion of the blends and recovery temperature.
