摘　　要：利用脉冲激励法和载荷法测试同一水泥基纤维复合板材的弹性模量,采用非线性拟合,建立两种方法的相关关系,为水泥基纤维复合板弹性模量的无损检测研究提供基础。利用脉冲激励法检测同一水泥基复合板材有机硅表面处理前后的弹性模量、剪切模量和泊松比,数据表明,有机硅表面处理工艺对板材抵抗变形能力无显著影响。Pulse excitation method and load method are used to test the elastic modulus of the same cement-based fiber composite board.The correlation between the two methods is established by nonlinear fitting,which provided a basis for the research of nondestructive testing the elastic modulus of cement-based fiber composite board.The elastic modulus,shear modulus and Poisson’s ratio of the same cement-based composite plate before and after silicone surface treatment are measured by pulse excitation method.The test data shows that the silicone surface treatment process had no significant effect on the deformation resistance of the plate.
