摘要：研究了 PET短纤维和硅灰石晶须混杂增强硅树脂复合材料的拉伸性能。结果表明 ,相对少量硅灰石晶须加入到 PET/硅树脂体系中会降低 PET纤维的增强效果 ,材料的拉伸强度降低 ,但当硅灰石晶须的加入量很多时 ,材料的拉伸强度反而会明显提高。笔者对硅灰石晶须的加入量对
The tensile properties of short PET fiber/wollastonite/silicone resin hybrid composites have been studied.It was observed thatthe addition of wollastonite whisker with relatively low vol- ume fraction to PET fiber/silicone resin system would lead to a reduction in the tensile stress of the hybrid composites.Butwhen a very high amount of wollastonite was added,for example,38% vol- ume fraction,tensile strength of the hybrid composite increased sharply,which waseven higherthan that of PET fiber/silicone resin composites with the same fiber loading.The tensile modulus was found to increase as the volume fraction of PET fiber in the hybrid composites increases,while the wollastonite loading had little effect on the tensile modulus of the hybrid composites.The change of PET fiber efficiency factor with the addition of wollastonite to PET/silicone system was presented quantitatively.
