以丁腈橡胶为基体,通过添加芳纶纤维制备了芳纶纤维增强橡胶复合材料(AFRC),研究了纤维长度、纤维质量分数对AFRC横向和纵向拉伸性能的影响。结果表明:随着纤维质量分数的增加,AFRC的横向和纵向抗拉强度呈上升趋势,且纵向抗拉强度普遍高于横向抗拉强度;纤维质量分数为4%、长度为3mm时,AFRC综合性能较优。
With nitrile rubber as the matrix,aramid fiber reinforced rubber composites (AFRC) were prepared by adding aramid fibers,and the effects of fiber length and fiber mass fraction on the transverse and longitudinal tensile properties of AFRC were studied.When the mass fraction increases,the transverse and vertical tensile strength of AFRC is increasing,and the initial tensile strength is generally higher than the transverse tensile strength;when the fiber mass fraction is 4% and the length is 3mm,the comprehensive performance of AFRC is better.
