Abstract: By the uniaxial tensile test, the effect of coupling agents on mechanical properties of the composite propellant with fillers different in surface property is studied in this paper. The results show that MAPO is an coupling agent of the coated AP and the uncoated AP, T313-B, T603, 5527 are the coupling agent of Al. Composite coupling agent T313 had the comprehensive function for the fillers above and the excellant synergism for the coated AP, especially. Additionally, the reasons that are also explained in this paper T313 could improved mechanical properties, and the direction to choose the coupling agents is suggested.
