Migration of Plasticizer between Bonded Propellant Interfaces
Plasticizer migration across bonded propellant interfaces during cure has been shown to have a measurable effect on propellant properties compared to each propellant by itself. This shows that the curing period is significant to the migration phenomenon.
The Diffusion of Components from Propellant and Liner at the Interfaces
Small molecule plasticizers and nitroglycerine (NG), which are abundant in propellants, can diffuse and migrate from the propellant column to the inhibitor during storage, seriously damaging...
- Why do plasticizers migrate from propellant to liner?
- The migration phenomenon occurs mainly due to the differential concentration of plasticizers and stabilizer between the additive part and the nonadditive part. All these components were added in propellant originally, and none was in liner, neither was in insulation, so they migrated from propellant to liner and insulation.
- Do plasticizers migrate?
- Until now, many current researches have focused on the study of the anti-migration of plasticizers . A research shows that plasticizer migration from the rocket propellant grain to the inhibitor may cause serious damage to the interface, which is prone to accidents .
- What is the dynamic migration process between propellant and liner interface?
- Based on classical MD simulations, the dynamic migration process of key components (NG, BTTN, MNA, 2-NDPA, and RDX) between the propellant and liner interface was simulated at room temperature.
- How do plasticizers migrate from a filler to an inhibitor?
- The insets in (a), c show the bonding state between the filler and the matrix under high magnification In composite propellants, plasticizers migrate from the propellant grain to the inhibitor under the influence of factors such as internal concentration, polarity, and the external environment.
- Does go improve the anti-plasticizer migration of HTPB propellant liner?
- Based on the above studies, GO in the HTPB propellant liner may exhibit a good anti-migration effect on small molecules through its unique structural properties. However, there are few reports on the application of GO to improve the anti-plasticizer migration of propellant.
- Does graphene oxide/HTPB nanocomposite liner migrate from solid propellant to inhibitor?
- The migrations of plasticizers and water molecules from solid propellants and surrounding environment to the inhibitor have always been the important issues. This study focuses on the preparation, characterization and anti-migration behavior of graphene oxide (GO)/HTPB nanocomposite liner.
