In order to improve the efficiency of β-CD, the inclusion complex of β-CD and resorcinol bisdiphenylphosphate (RDP) (β-CD@RDP) was prepared, which β-CD was as the host component and RDP was as the guest. The structure and thermal stability property of β-CD@RDP was also characterized. EP/β-CD@RDP composites were prepared by adding β-CD@RDP into EP matrix. The results of thermogravimetric test showed that the flame retardant systems could effectively increase the corresponding temperature of EP matrix to reach the maximum thermal decomposition rate, and exhibited good char-forming property. When the amount of β-CD@RDP in EP was 20wt％, the limiting oxygen index (LOI) value of EP was increased to 26.5％ from 19.8％, and the vertical burning test (UL-94) reached V-1 level. The cone calorimeter test indicated that 20wt％ loading in EP could reduce the peak of heat release rate (PHRR) and the total heat release (THR) of EP by 94.7％ and 93.4％ respectively, and the peak of smoke production rate (PSPR) and the total smoke production (TSP) was reduced by 16.7％ and 22.2％, respectively. Therefore, the addition of β-CD@RDP could reduce the fire risk of EP effectively.
