| Abstract: |
| A carbonyl iron/strontium ferrite/MVQ wave-absorbing composite was prepared，and the effect of the blending ratio of carbonyl iron/strontium ferrite on the properties of the composites was investigated.The results showed that，as the addition level of carbonyl iron decreased while total filler volume fraction was constant，the absorption peaks of carbonyl iron/strontium ferrite/MVQ composites were between the peaks of carbonyl iron/MVQ and strontium ferrite/MVQ composite；the frequency band of the composites in the range of lower than -10 dB was increased at first and then decreased；the absorption peaks moved to higher frequency position；the tensile strength and the elongation at break were changed a little，the compression set was decreased and the dynamic properties were improved. |
