Dissipative Particle Dynamics Study on the Mesoscopic Structures of CL-20-Based PBX

摘要

This paper applied the dissipative particle dynamics to study the compatibility and the mesoscopic structures and evolution procedures when combined with the CL-20 for the four binders like Estane5703, HTPB, GAP and PBAMO.The results showed that phase separation in different degrees occurs in simple substance like CL-20.Through the simulation of the renetion(x) process, with the change of reaction time, the binder in the CL-20 begins with the initiative mixing to the subsequent separation in different degrees.And the ascending of the temperature will lead to the better diffusion for the binders into the CL-20.
