Abstract—

The influence of the orientation of the reinforcing fibers on the deformation and damage of the shape memory composite during bending and torsion, as well as the restoration of the initial shape of the sample upon activation of the shape memory effect (SME), has been studied. The composite is a three-layer carbon fiber impregnated with a shape memory polymer, the activating factor of which is temperature. The influence of fiber orientation on the formation of systems of irreversible structural defects in the process of shape fixation was revealed. The distribution of these defects determines the degree of shape recovery upon SME activation and the reproducibility of the original shape upon repeating the “shape fixation–recovery” cycles.

各向异性对形状记忆聚合物复合材料变形的影响

摘要-

研究了增强纤维的取向对形状记忆复合材料在弯曲和扭转过程中变形和损坏的影响，以及在激活形状记忆效应（SME）后恢复样品初始形状的影响。 。该复合材料是三层碳纤维，其中浸渍有形状记忆聚合物，其活化因子为温度。揭示了纤维取向对形状固定过程中不可逆结构缺陷体系形成的影响。这些缺陷的分布决定了SME激活后形状恢复的程度，以及重复“形状固定－恢复”循环后原始形状的可复制性。
