高填充复合推进剂的初始粘弹性泊松比

Initial Viscoelastic Poisson Ratio of High-Filled Composite Propellants

本文从粘弹性力学和复合材料力学理论说明，高填充（固体填充比φ＞０．６）复合固体推进剂的初始粘弹性泊松比（０．０１～１０ｓ）可能小子０．４，并讨论了粘弹性泊松比的测试方法，利用一种新方法得出了相应的实验数据。

Based on the viscoelastic mechanics and composite material mechanics, it is shown that the mittal viscoelastic Poisson' s ratio of high -filled composite propellant at 0. 01 ～10s may be less than 0. 4. The methods for measuring viscoelastic poisson' s ratio are discussed, and tested data are given by means of a new method suggested by the paper.
