| Abstract: | By means of SEM and micro-dynamic tensile instrument, the fracture cross sectionmicroscopic pattern of HTPB propellants was observed and the fracture behavior of midget tensilesamples at strain state is analysized. It is shown that the microstructure change in the tensile productcan presage the macroscopic mechanics properties of the propellant- So improvement of the interfacecharacteristics between the propellant binder and solid particles is an important way to enhance themechanic properties of the solid propellants. |
