Abstract
The paper analyzed the effect of tensile conditions on the shape memory effect of PLA plates. The experimental results showed that the PLA plates presented excellent recovery ratio and recovery stress at lower stretch temperatures. In shape memory system of PLA, the crystal regions acted as network points significantly influenced the shape memory effect. The change of crystal structure of PLA plates at different strecthing conditions was investigated. The structural evolution model of lamallae during the stretching process were established.
