Dynamic Mechanical Properties of a Novel Structural Radar Absorbing Materials

Abstract:

A novel structural radar absorbing materials (SRAM), which give the new absorbing microwaves function to the normal resin-base composites, were prepared. The dynamic compressive tests of SRAM were carried out along both in-plane and normal plane directions of composites by means of the Split Hopkinson Pressure Bar (SHPB). In compressive test along in-plane direction, failure happened at the interface between fiber and matrix. Fracture mode and mechanism was proposed to explain these results. The adding of magnetic absorbing particles resulted in the deterioration of the compressive properties. But there was no obvious decrease on compressive strength of SRAM with the radar absorbing properties.
