The invention provides an evacuation platform system based on a composite material. The system comprises an installation plate, a supporting assembly, a stabilizing rod, a platform assembly and a climbing assembly. According to the arrangement of the supporting assembly and the platform assembly, an embedded plate is embedded in an embedding groove and bolts screwed into a first installation holeand a second installation hole to realize assembly operation of the platform system, installation of the platform system is convenient, a lot of labor force and time are saved, and installation efficiency of the platform system is improved; according to the arrangement of the platform assembly, a platform body and the embedded plate are made of the composite material which is a material of excellent dynamic performance, five times steel in strength, resistant to a high temperature of 2000 DEG C, one fifth of the steel in specific gravity, and excellent in flame retardant performance, so stability of the platform system is improved, phenomenon of collapse or crack is avoided, and safety performance of the platform system is improved; and the evacuation platform system based on the compositematerial is simple in structure, convenient and rapid in operation, and convenient for market promotion and application.
