| Abstract: |
| The effects of TEA(triethanolamine),BF 3 and TEA·BF 3 complex on rheological properties of Al/HTPB, AP/HTPB, AP/Al/HTPB composites slurry were studied by rotational viscometer.The results show that shear rate exponent n decreases due to the hydrogen bonding effect and TEA-Al reaction in presence of BF 3, and the coefficient K of shear viscosity increases with HTPB-BF 3 interaction,so that the apparent viscosity increase sharply under low shear stress and the flowability and leveling of HTPB propelland slurry is poor. |
