| Popis: |
Polymer bonded explosive(PBX) is a composite in which energetic material is highly filled in a polymer binder matrix. For safety reason, however, in experimental studies, corresponding material (Dechlorane) which has similar density and melting point was used. To apply for real system, a comparison of properties of composite filled with energetic material and corresponding material is needed. Not only components of composite like filler, binder and plasticizer but also filler content and distributive properties are important factors determining properties of simulant. Unlike previous low filled PBX, properties of highly filled PBX is greatly influenced by filler content. Rheological properties of composite filled with energetic material and corresponding material can be compared by analyzing effects of filler properties - e.g., mean particle size, particle size distribution and particle shape, etc. - on rheological properties. Rheological properties of two composites of various content over than 50wt% have been investigated by using rotational rheometer with parallel plate. |
