利用超声脉冲技术研究了平面谐波在硼-环氧复合材料中的频散行为。对于平行或垂直于光纤传播的纵波和横波，确定了群速度对频率的依赖关系。还获得了复合材料的静态弹性模量，并且在第一近似下，发现该材料是四元的。
An ultrasonic pulse technique was used to investigate the dispersive behavior of plane harmonic waves in a boron-epoxy composite. The dependence of group velocity upon frequency is determined for longitudinal and transverse waves propagating either parallel or perpendicular to the fibers. The static elastic moduli for the composite are also obtained, and to a first approximation the material is found to be tetragonal.
