ABSTRACT
Plastic bonded explosives (PBXs) form a new family of the modern types of
explosives based on elastomeric binders,. The high mechanical strength, in addition
to the good explosive characteristics, long term thermal stability and relative safe`ty
to handling and usage have stimulated the research and development work in this
field. This investigation is directed to the formulation of RDX based PBX
compositions different binder such as polyurethane based on HTPB, and GAP, and
fluorocarbons (fluorel) as energetic polymeric binders. Slurry and casting techniques
were used to prepone of different explosive compositions based on fluorel binder
(5,8,11,15 and 20% fluorel) and polyurethane binders based on HTPB or GAP (12,
15, 18 and 21%) contents. The study measures the explosive characteristics.
Moreover, the effect of addition aluminum powder on the sensitivity and performance
of PBX these formulations was investigated.
It was found into the investigated PBX compositions have high` performance and
reasonable sensitivity to different impulses. It is proved that these PBX formulations
could be prepared by simple techniques.
