玻璃纤维增强PTT复合材料热性能和动态力学性能

omposites of glass fiber reinforced PTT with various amount of glass fiber and silane coupling agent were prepared by melt blending. The thermal property and dynamic mechanical property of the composite were studied by DSC and DMA, the interfacial action of PTT/Glass fiber blends was analyzed by sacaning electron microscopy. The results showed that the ability of composite to crystallize and storage modulus increase with the increase of content of glass fiber; with the addition of silane coupling agent, the nucleation effect on composite is improved, the mechanical property of composite enhances, the internal friction peak move to hig temperature.
