Abstract: Basing on the results of investigations on the mechanical properties of composite solid propellants,combining with the quintessence of Bonding Agent Function Model,the advanced theory of network and morphology and the mature theory of particulate filled composite materials,a mesophase(interphase)mechanical model of composite solid propellants was put forward.The quantitative relationship between the structure factors of propellants and the mechanical characteristic parameters( σ,ε ),which conforms well with the results of verifying tests and previous experiments was established by mechanics and mathematics deducing.The method of tailoring the ratio of mesophase modulus to matrix modulus provides a new technique approach to further enhance the mechanical properties of composite solid propellants
