Summary:The invention discloses a composite explosion suppression body based on foam metal filled with an ultrafine powder explosion suppressant. The composite explosion suppression body is formed by bondingan overpressure buffer layer with an explosion blocking layer. Dense rigid microstructure layout is adopted on the surface of the overpressure buffer layer. The explosion blocking layer is formed by filling ultrafine powder into iron-nickel foam metal. The rigid microstructure can resist explosion overpressure, and the direction and magnitude of explosive shock waves can be decomposed in a multi-angle mode so as to achieve the purpose of buffering. When pressure is borne continuously, the porous structure of the iron-nickel foam metal and NaHCO3/rock powder ultrafine powder can fully absorb explosion negative pressure, and spreading of explosion flames can be effectively restrained. According to the composite explosion suppression body, the explosion overpressure with a huge overpressure amplitude value can absorb
