摘　　要：主要研究硫酸钙晶须部分或全部替代玻璃纤维在PBT材料中的效果,以及该复合材料在不同硫酸钙晶须含量下,其拉伸强度、弯曲模量、缺口冲击和产品翘曲的变化情况。结果表明:PBT复合材料的物理性能随着硫酸钙晶须含量的增加而降低;随着硫酸钙晶须含量的增加,翘曲度降低。This paper mainly studies the effect of calcium sulfate whiskers in PBT glass fiber reinforced material, and the changes of tensile strength, bending modulus, notch impact and product warpage of different calcium sulfate whiskers in the composite. The results show that when the content of calcium sulfate whiskers increases, and the properties of the composites are reduced. With the increase of calcium sulfate whisker, the warpage is improved.
