摘要：
To improve mechanical properties of the metal mesh reinforced thermoplastic polyurethane elastomer (TPU) hollow fiber tube, we first discussed the effect of treatment temperatures on microphase separation of the TPU. The chemical microstructures of the TPU were characterized by X-ray diffractometer (XRD). The dynamic mechanical properties of the TPU were measured by DMA. The results exhibited two glass transition temperatures, which showed the distinct microphase separation. In addition, the mechanical property of hollow fiber tube was analyzed by flexural stress and twisting performance, and the mechanical properties of the metal mesh to enhance the hollow fiber tube was increased at different treatment temperature, which indicated that the microphase separation has a great influence on the mechanical properties of the metal mesh to enhance the hollow fiber tube.
