Properties Of Composites

Microwave absorbing properties of composites containing activated carbon-fiber felt screens (ACFFSs) have been investigated. Samples with different types of ACFFSs embedded in composites were fabricated. Experiments were carried out to test the absorption effect of embedded ACFFSs. It is found that both the ACFFS patterns and its element configurations are critical for the reflection properties of samples. With the distance between strips and the width of strips in the inductive ACFFS decreased, the absorbing properties of composites are improved. The composite obtains a reflection loss below –10dB in 8~18GHz, which is the frequency range the radar works in, when the distance between strips and the width of strips are 7mm and 5mm respectively. With the side of plates and the distance between plates in the capacitive ACFFS reduced, the absorption effect of composites rises. When the distance between plates and the side of plates are 5mm and 7mm separately, the composite achieves a reflection loss below –10dB over a bandwidth of 8.7GHz and the minimum value of absorption rate reaches –31.7dB.
