Introduction Thermal performance is a very important property for energetic materials.
It’s widely used in the thermal analysis of energetic materials.
By analysing energetic material and the mixed system containing the energetic material and contact materials, or a energetic material mixed system and its components, obtain a mixed system and energetic materials decomposition peak temperatures.

Spherical Auxetic Shells Teik-Cheng Lim School of Science and Technology, SIM University, Singapore alan_tc_lim@yahoo.com Keywords: Auxetic materials; Bending stress; Membrane stress; Spherical shells.
Materials that exhibit negative Poisson’s ratio are called auxetic materials.
Although such materials are quite rare, they nevertheless exist as naturally occurring materials and artificially made materials.

These types of structures are classified like composite materials with polymeric fiber matrix and in this field of activity are not many investigations.
In order to develop a more advanced model it is necessary of a multidisciplinary research group in order to combine the most advanced sciences at his moment, like: composite materials, textiles - microfibers, chemistry and also mechanical science.
