Why is the phase separation between Gap and HTPB shorter?
It indicates that the required time for phase separation between GAP and HTPB in GAP/HTPB/DOS is shorter than that in GAP/HTPB/A3/DOS, and two reasons account for this phenomenon. First internal friction and viscosity of A3 molecules are higher than that of DOS; therefore, polymer diffusion in the blend becomes difficult upon addition of A3.
Which polymers are used to simulate phase behavior in DOS plasticizers?
In our research, two kinds of polymers GAP ( X ̅ n =37) and HTPB ( X ̅ n =56), which adopted as the propellant binders, were utilized to simulate their phase behaviors in the presence of DOS or A3/DOS plasticizers.
What is the rheology of gap/HTPB propellant slurry plasticized by a3/dos?
The rheology of GAP/HTPB propellant slurry plasticized by A3/DOS was studied. First, single-phase aggregations of GAP and HTPB appear slightly in A3/DOS whereas it is conspicuous in DOS, which results from the small surface tension between the GAP/HTPB plasticized by A3/DOS and the weak thermal diffusion of this blend.
Can gap be used in HTPB systems?
From an application perspective, it is desirable to introduce GAP and the energetic plasticizer (A3) simultaneously into HTPB systems (including DOS); in this way, the energy characteristics of propellant can be significantly improved, and the surface tension between GAP and HTPB may be decreased under the influence of plasticizers.
Which plasticizer is suitable for gap/HTPB propellant?
This demonstrates that the A3/DOS plasticizer is suitable for the GAP/HTPB propellant. There are many reasons that contribute to this. First, compared to GAP/HTPB/DOS, the GAP/HTPB/A3/DOS blend shows a better compatibility. Next, the blend has a weakened diffusion due to A3, and the required time for phase separation becomes longer.
What are HTPB polymers and plasticizers?
By means of the DPD code in Material Studio 7.0 software ( 26 ), we first presented the molecular structures and coarse-grained models of the polymers (Figure 1) and plasticizers (Figure 2 ). HTPB chains contain different configurations of trans -2,3-butadiene ( l ), cis -2,3-butadiene ( m) and vinyl -1,2-butadiene ( n ).
