A microwave absorptive composite suitable for use in ships, aircrafts and the like comprises an outermost layer of a thermosetting resin-impregnated, fibrous sheet; an intermediate layer of a normally liquid, carbonblack-containing silicone rubber sheet; and an innermost layer of a reinforced thermosetting resin sheet, the three layers being integrally laminated in that order. The silicone rubber is curable at room temperature or with heat.

Microwave-absorptive composite

A multi-layered microwave absorber suitable for use in ships, aircrafts and the like comprises a plurality of layers differing in impedance which are bonded together into an integral sheet structure by a silicone-type adhesive compound applied to a coat thickness of less than 0.1 mm. The absorber is capable of wave absorption over a wide band, free from deformation or distortion, and highly heat-resistant and weather-proof. A method of manufacturing the multi-layered microwave absorber is also disclosed.
