摘　　要：包覆层是固体推进剂的重要组成部分，其力学性能直接关系到固体推进剂结构的完整性。丁羟具有一系列的优点而广泛应用于复合固体推进剂。本文重点研究丁羟包覆层的力学性能。通过正交试验法，研究了丁羟、甲苯二异氰酸酯、中空玻璃微珠、云母、三氧化二锑、氢氧化铝等因素对丁羟包覆层力学性能的影响。根据试验数据得到了丁羟包覆层力学性能预示模型。验证试验证明包覆层能够满足试验需求，预示模型具有工程指导意义。The liner is an important part of solid propellant. Its dynamic properties have direct connection with the integrity of the solid propellant structure. HTPB is applied in composite solid propellant because of its merits. In this article, the dynamic properties of HTPB liner are presented. With orthogonal experiments, the effect of many factors to the HTPB liner＇s dynamic properties is researched. The factors include HTPB, TDI, hollow glass micro-ball, isinglass, Sb2O3, Al（OH）3 and so on. With the experiment data, the prefigurative model of the HTPB liner dynamic properties is offered. The following experiment proves that the liner can meet the need of experiment, and the prefigurative model has application guide significance.
