摘要
考察了纳米碳酸钙(Nano-CaCO_3)含量及表面处理对玻璃纤维增强聚苯硫醚(PPS／GF)三元复合材料拉伸性能的影响。结果表明：复合材料的拉伸弹性模量、拉伸强度和拉伸断爱强度均有提高；当φ_f小于4％时,拉伸断裂伸长率隨着φ_f的增加而明显增大,然后趋于平缓。经钛酸酯处理的Nano-CaCO_3填充PPS／GF体系的拉伸力学性能略优于经硬脂酸处理的复合体系。
It investigated the influencing effects of the content and surface treatment of nanometer calcium carbonate （Nano-CaCO3） on the tensile properties of ternary composites involved glass fiberreinforced polyphonylene sulfide （PPS/GF）. The results showed that the modulus of elasticity, tensile strength, and tensile rupture strength of the composites all increase with the increase of the content of Nano-CaCO3. When φf is less than 4 %, the tensile elongation at break of the composites increases obviously with the increase of φf and then goes smooth. The tensile properties of the PPS/GF/NanoCaCO3 system treated with titanate are better than those of the system treated with stearic acid.
