摘要

A new type of sandwich composite panel (SCP) is fabricated, with a novel combination of a core of fused -double-3D-mat composites made of E-glass sandwiched between layers of aramid-fibre mats for the efficient dissipation of energy when subjected to a ballistic impact. Novel methods of the SCP fabrication and indige-nous techniques of the embodiment of the dilatant fluids within its cores have been discussed. The fabricated composites were subjected to high-velocity ballistic impact using 9 mm bullets of average velocity-400 m/s. It is observed that due to the incorporation of the dilatant fluid within the SCP, it could absorb 20.24% of the energy incident on it. The amount of energy absorbed is 43.96% more than that absorbed by the hollow com-posite and it recorded a percentage increase in absorbed energy per unit increase in mass by 22.43%. This allows the fabricated SCPs to be used in applications requiring enhanced energy dissipation.
