Preparation and Characterization of Wave-absorbing Coated Radiation-proof Composite Fabric

摘要

Absorbing powders were covered on the surface of radiation-proof fabric by coating technology. Morphology, structure, property, electromagnetic parameters and reflectivity of the coated composite fabric were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), differential scanning calorimetry (DSC), thermogravimetry (TG) and microwave network analyzer respectively. The results showed that the coating on the surface of radiation-proof fabric was crystal, acetylene carbon black (ACB) and carbonyl iron powder (CIP) owned better stability of thermodynamics compared with alloy powder (AP). ACB coated composite fabric and CIP coated composite fabric has excellent absorbing effect on the radar X, Ku band, while AP coated composite fabric has absorbing effects on low-frequency.
