摘    要:通过在涤纶/氨纶管状织物上复合丝素/聚氨酯的方法制作一种复合结构的小口径人造血管,这种复合结构的人造血管截面显现多微孔结构,并且微孔分布均匀,内表面也较光滑.力学测试的结果表明,随着管壁厚度的增加,人造血管的断裂强力、断裂功和初始模量都上升;随着氨纶含量的增加,人造血管的断裂功和初始模量下降,但断裂伸长和断裂强力先增大...

关 键 词:超细丝素粉体  聚氨酯  管状织物  人造血管  力学性能

Abstract:In this paper, a kind of composite microtube which made from superfine silk powder and polyurethane, reinforced by polyster and spandex tubular fabrics were examined. The cross-section of composite microtubes was mieroporous, and mieropores were uniform distribution, the inner surface was relative smooth. The results showed that the wall thickness of composite microtube increased led to the strength, the breaking work and the initial modulus increased; the spandex content increased brought about the initial modulus and the breaking work decreased, but the breaking extension and the breaking load were first increased and then decreased; and all the mechanical properties decreased as the SFSP content increased.
Keywords:superfine silk powder  polyurethane  tubular fabric  vascular graft  mechanical property
