摘要
用一维应变实验方法研究碳酚醛材料的层裂特性，给出了损伤程度随撞击速度的增加而增加的指函数准则，及产生层裂损伤的临界撞击速度。发现在层裂特性研究中，应力波衰减有重要意义。
The spallation property of carbon fiber reinforced phenolic-resin composite is studied by uniaxial strain experiment.The criterion of spallation for this material given in this paper is represented by an exponential function of damage degree with impact velocity.The threshold velocity of incipient spallation is given.It is found that the attenuation of stress wave is important for study of spallation property.
