Abstract：In order to prepare structural absorbing materials with mechanical properties and electromagnetic absorption properties, a kind of absorbing composites with carbonyl iron powders (CIP) as absorbent, glass fiber(GF) as the transmittance layer, carbon fiber(CF) as the reflective layer, and epoxy resin(EP) as matrix was designed and fabricated by vacuum assisted resin infusion process. The effect of different mass ratios of CIP/EP on the mechanical properties and microwave absorption properties of the composites was studied. The results of FTIR and DSC suggest that there is not a chemical reaction between CIP and EP. SEM shows that CIP can be dispersed uniformly in EP resin matrix and not toward the surface of the fibers. The results of mechanical tests indicate that the best mechanical properties of the CIP/GF/CF/EP composites are at a mass ratio of 3:10 of CIP to EP. The tensile strength and tensile modulus are 347.56MPa and 25.99GPa, 4.3% and 5.7% higher than that of GF/CF/EP composites. The flexural strength and the flexural modulus are 339.6MPa and 23.7GPa, 18.2% and 71.2% higher than that of GF/CF/EP composites. Vector network analysis proves that the absorbing performance of composites absorbing plate is increased and the peak of reflection absorbing loss is moved toward the low frequency band with the increase of CIP.
