“…A lot of research has been carried out on the tensile and compressive mechanical properties of HTPB propellants in the past period of time [1][2][3][4][5][6]. The effects of temperature and loading speed on the mechanical properties of propellant under uniaxial loading were studied [7][8][9][10][11][12][13][14].…”

A new type of shear loading fixture and tensile testing machine with a refrigeration system was utilized to conduct Hydroxyl-terminated polybutadiene (HTPB) propellant low strain rate (0.01 ~1.00 s À 1 ) shear loading tests at low temperature (223 K ~298 K). The shear strength and shear modulus of the HTPB propellant under different loading conditions were studied, and the master curves of the shear mechanical properties were constructed. It is found that the shear strength of HTPB propellant increases with increasing of shear strain rate and decreasing of temperature. The change of shear strength with temperature and strain rate conforms to the linear double logarithmic relationship. The initial shear modulus has a good linear double logarithmic relationship with the strain rate but changes nonlinearly with the logarithmic temperature. The shift factor of HTPB propellant shear strength and initial shear modulus changes exponentially with temperature after taking logarithm. The master curve of the initial shear modulus of HTPB propellant shows an "S"-shaped change trend, and a linear equation is used to fit the master curve of shear strength to obtain a better fitting effect.

Composite propellant must possess sufficient structural capability to withstand the various loading conditions. Several attempts are made worldwide to evaluate mechanical properties of composite propellant at different temperatures and strain rates but effect of pressure has not been yet fully elaborated. In the present study, effect of pressure on mechanical properties of composite propellant was evaluated and discussed to obtain the best possible simulation of firing phenomena. The Universal Testing Machine (UTM) was used to characterize the mechanical behavior of AP/ Al/ HTPB based composite propellant at different strain rates of 0.
