摘　　要：本文对钢丝帘线／橡胶复合材料中的钢丝帘线泊松比的定义提出了新的见解，建议用钢丝帘线横截面变化率代替其横向应变。In this paper,a new viewpoint of defination of Poisson ration for steel cord in cord-rubber composites is proposed.It is suggested that the transverse strain of the steel sord should be replaced by the section varying ratio of the cord.An exper imental method by using scanning electronic microscope to measure the section variable ratio of the cord is described.

关 键 词：帘线 橡胶 复合材料 钢丝帘线 子午线轮胎
