摘　　要：刀刃形行波测试载体在吸波材料性能测试时,出现后缘行波散射分离不彻底,其刃形边缘易被碰伤,划伤测试人员,且在碳纤维测试载体上加工刃边极易造成碳纤维分层破坏。为解决这些问题,设计了一种新型的令牌形碳纤维测试载体。从原理、仿真、测试等方面对2种测试载体做了对比。测试结果表明:令牌形碳纤维测试载体具有行波散射分离度高、无前后缘散射耦合现象、适用于碳纤维材质、安全性高等特点,解决了国内现有刀刃形行波测试载体安全性差,不适用于低频、大尺寸碳纤维材质的难题。Trailing edge traveling wave scattering separation was incomplete in absorbing material performance testing of the traveling wave test carrier with knife-edge,At the time operators were easy to be scratched for the bruised blade edge,Even carbon fiber layer was damaged for the machining of the carbon fiber blade edge.So a new kind of carbon fiber test carrier with token form is designed to solve these problems.Two kinds of carriers were compared respectively from the aspects of theory,simulation and testing etc.The results showed that carbon fiber test carrier with token had high traveling wave scattering separation degree and high safety,and had no scattering coupling phenomenon between leading and trailing edge.It also applies to the carbon fiber material.Problems were solved about the poor safety knife-edge carrier which was not proper to be applied to low frequency,large size carbon fiber material.
