3010 PLA/PCL/LTIポリマーブレンドの相構造と破壊特性(S40-3 生分解ポリマー,木質材料の強度評価,S40 バイオマス由来材料の成形加工と特性評価)
詳細
LTI was added to blend of PLA and PCL to improve the immiscibility between the two biodegradable polymers. Fracture properties of PLA/PCL and PLA/PCL/LTI were evaluated and compared to assess the effect of LTI on the fracture behavior. The critical energy release rate at crack initiation, J_<in>, was improved effectively due to LTI addition. Fracture surfaces were also examined using SEM to characterize the fracture mechanism. It was confirmed that the size of PCL spherulites became smaller by adding LTI, and hence void formation was inhibited, resulting in the improvement of the fracture property.
