摘要
运用逐步提高优选法和抛物线优选法制备了高力学性能的玄武岩纤维(BF)和聚丙烯纤维(PPF)复合板材,研究了m(BF)/m(PPF)对复合板材力学性能的影响。2种优选法得到的结果基本一致,当w(BF)为30%时,复合板材的力学性能达到最佳,最大拉伸强度和模量分别为99.1 MPa和3.4 GPa,最大弯曲强度和模量分别为158.3 MPa和1.30 GPa。
The authors prepared basalt fiber(BF)/polypropylene fiber(PPF) composite plate with desired mechanical properties by means of gradually increasing optimum seeking method and parabolic optimum seeking method, and studied the influence of mass ratio of BF to PPF on mechanical properties of the BF/PPF composite plate. The mechanical properties of the BF/PPF composite plate reached their optimum values when the mass content of BF was 30%. There was no difference in the dependence of the mechanical properties on the BF content for the composite plate prepared by either optimum seeking method. The maximum tensile strength and modulus were 99.1 MPa and 3.4 GPa, respectively, and the maximum bending strength and modulus were 158.3 MPa and 1.30 GPa, respectively.
