摘要:

在总结归纳复合固体推进剂力学性能研究的基础上，吸取键合剂作用模型的优点，结合新近提出的网络与形态结构理论，并引入颗粒充填复合材料中的成熟理论，提出了一个描述复合固体推进剂力学性能的过渡相（中间相）模型。通过力学、数学推导建立了复合固体推进剂的结构因素与力学性能表征参数（σ，ε）的定性关系，这与验证实验及前人的结果基本一致。其中提出的关于过渡相模量与基体模量匹配的调节方法，为进一步提高复合固体推进剂的力学性能提供了一条新的技术途径。

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
