| 摘 要： | 为了提高形状记忆聚合物(SMP)的刚度性能,研制了纤维增强苯乙烯基形状记忆聚合物复合材料(SMPC),对其动态力学和弯曲性能进行了测试分析,采用有限元分析法得到SNIP和SMPC梁的弯曲变形规律,并利用经典层合板理论对其刚度进行分析.结果表明:SMPC材料的弯曲回复率和抵抗变形的能力都高于纯SMP材料.在等温度条件下,SNIP梁和SMPC梁的变形与载荷呈线性关系;在等载荷条件下,SMP梁和SMPC梁的变形与温度呈非线性关系.SMPC的刚度特性使其应用领域得到拓展.

| Abstract: | A carbon fiber reinforced styryl shape memory polymer composite (SMPC) is developed for improv- ing the stiffness of shape memory polymer (SMP). In this study, the dynamic mechanical property and the bending property of SMPC are investigated. The characteristics of bending deformation of SMP and SMPC are obtained using ANSYS method. The stiffness is analyzed based on traditional laminated plate theory. The study shows that the ability of resistance to deformation and the bending recoverability of SMPC mater... |
