### Quantifying Porosity Influence on Metallic Particle

Among the particle reinforced composite polymeric composites tested herein the most interesting behavior especially sized in its thermal property was encountered for the 80 Al particles embedded into the epoxy matrix selected. The experimental data as will be shown next were influenced by the presence of porosities within the structure.
