摘　　要：高碱玻璃布材料在航空航天领域有着较广泛的应用,其高压力学性能的研究逐渐受到人们的关注。针对一种新型高碱玻璃布材料,通过轻气炮实验进行冲击压缩力学性能研究。采用非对称碰撞直接测量法测量并计算激波速度(D)与波后质点速度(u)的D-u型的Hugoniot曲线,并以Hugoniot曲线为基础建立该材料的Grüneisen状态方程,求得相应的材料参数。Alkali glass fiber reinforced cloth is widely used in aerospace field, and its high pressure mechanical properties become the hot spot in recent years. Aimed at a new type alkali glass fiber reinforced cloth, its impact compression behaviors were investigated by means of Light Gas Gun （LGG）. The shock wave velocity （D） and the particle velocity （u） behind shock wave were measured and calculated by using Asymmetry Impact and Direct Measurement. Based on the experimental results and calculated results, a D-u type Hugoniot curve was obtained. The Gruneisen state equation of alkali glass fiber reinforced cloth and its coefficients were obtained on the basis of its Hugoniot curve.
