短切碳纤维对聚氨酯泡沫塑料吸波性能影响

his paper studies the carbon fiber content, the dimensions of the material in 2 ~18GHz within the influence of absorbing properties and different concentration gradient distribution of foam plate material absorbing properties. Using digital scalar network analyzer (Agilent 8757 E) measuring the absorbing properties, and the results show that: the fine, carbon fiber size absorbing performance is better; Thickness of the same even a single absorbing materials in carbon fiber volume content presented the best performance in 3%, from the content function are lower; Absorbing material thickness is at the same time, carbon fiber different concentration gradient distribution of absorbing body absorbing performance is better than a single homogeneous materials.
