Abstract

Structural microwave absorption material has become one of the key research directions for microwave absorption materials since they have a combination of mechanical properties, microwave absorption properties and excellent designability. To this end, this work was conducted to prepare two kinds of modified carbonyl iron powders, KH550-CIP and EP@CIP, by surface modification of carbonyl iron powder (CIP) with silane coupling agent (KH550) and epoxy sizing agent, respectively, and to prepare CIP/GF/CF/EP laminate-structured absorption composites using a vacuum-assisted molding process (VARI). Then the effects of CIP surface modification on the microscopic morphology, mechanical properties and microwave absorption properties of the composites were investigated. The modified CIP/GF/CF/EP composite has increased strength, reduced modulus and a significantly larger effective absorption bandwidth, making it a structural absorbing material with practical applications. It is found that KH550-CIP/GF/CF/EP is more outstanding in absorption performance with the minimum reflection loss value of − 31.6 dB at 16.44 GHz and the effective bandwidth of 4.56 GHz, while EP@CIP/GF/CF/EP was more improved in mechanical properties with the tensile strength of 366 MPa, flexural strength of 320.6 MPa, compressive strength of 275.5 MPa, and interlayer shear strength of 33.68 MPa.
