Abstract:

An operationally simple blendable approach to producing structural energetic composites loaded with nanoaluminum n-Al particles coated by perfluoropolyethers PFPE yields shape moldable, structurally flexible materials. The epoxide system of polyethylene glycol diglycidyl ether PEG-DGE and triethylenetetramine TETA are partially cured with an energetic blend of n-AlPFPE core-shell particles and mechanically mixed and produce a homogeneous composite material whereby energetic potency is indefinitely shelf-stable. The composites are characterized by a suite of thermal techniques using DSC, TGA, and SDT in addition to open flame burn rate and heat of combustion measurements. This composite system may further expand the use of energetic materials with tailorable exothermic properties.
