In this study, in order to improve the impact resistance of the B4C tile-inserted B4Cp/Al7075 hybrid composite, a control method of the B4C/Al7075 interface was developed and the characteristics of the controlled interface were analyzed. B2O3, Ni, and Si were coated on the B4C tile surface using additional thermal oxidation, electroless plating, and plasma spraying. The coated B4C tile is inserted into the B4Cp/Al7075 composite material using the liquid pressurization method. Interfacial energy, bonding strength, and impact resistance were measured to analyze the effect of the coating. All coatings enhanced interfacial energy, bonding strength, and impact resistance, and in particular, it was confirmed that the impact resistance increased by 86.8% when B2O3 coating was used. This study is significant in developing and analyzing a core surface treatment method that improves the performance of B4C/Al series composites, which are attracting attention as next-generation lightweight amour and bulletproof materials.
