【摘要】 通过熔融共混制备玄武岩纤维（BF）/尼龙6 （PA6）复合材料,研究化学处理BF对复合材料界面结合性能的影响,并对BF与复合材料进行微观表征。结果表明,H₂SO₄与KOH处理后的纤维表面均发生变化,与PA6基体之间的界面结合强度有所提高,1 mol/L的H₂SO₄处理的复合材料的力学性能最佳,拉伸强度为102.44 MPa,冲击强度为15.38 k J/m²。更多还原

【Abstract】 Basalt fiber（ BF）/nylon 6（ PA6） composites were prepared by melt blending. The effect of chemical treatment of BF on the interface bonding properties of composites has been studied,and BF and composites are also been micro-characterized. The results showed that the surface of the fibers changed after H₂SO₄ and KOH treatments,and the interface bonding strength with the PA6 matrix was increased. The mechanical properties of the composites treated with 1 mol/L H₂SO₄ were the best,with a tensile strength of 102. 44 MPa,and the impact strength is 15. 38 kJ/m².更多还原
