Abstract

Graphene-reinforced aluminum matrix composites (AMCs) have strong potential as lightweight materials with enhanced mechanical performance. This systematic review examined fabrication methods, optimal compositions, and mechanical improvements in AMCs reinforced with graphene nanoplatelets (GNP), graphene nanosheets (GNS), graphene oxide (GO), and reduced graphene oxide (rGO). The review covered 25 indexed international journal articles published between 2012 and 2024 from Scopus, Google Scholar, and Web of Science, with article selection following the PRISMA framework. The findings show that planetary ball milling, powder metallurgy, sintering, friction-stir-based processing, wet coating, and High Pressure Torsion (HPT) vary in effectiveness in achieving graphene dispersion and interfacial bonding. Hardness increased by up to 43%, tensile strength by 317%, and yield strength by 25% with rGO contents below 1 wt.%. HPT increased hardness from 64 to 122 HV at 0.25 wt.%, while RFSSW improved shear strength by 31% and fracture toughness by 20%. Key research gaps include limited hybrid fabrication studies and the lack of standardized industrial-scale testing parameters.

Abstract

Multilayer hybrid ballistic plates have been developed to provide lightweight protection with high penetration resistance. In these structures, interlayer bonding is critical because poor adhesion can promote delamination and reduce ballistic performance. This article presents a mini review of studies published between 2015 and 2026, focusing on adhesive properties, surface preparation, vacuum lamination, void formation, and ballistic performance. The reviewed studies indicate that adhesive bonding and vacuum-based lamination techniques can improve consolidation and promote more uniform adhesive distribution in hybrid armor systems. Appropriate vacuum pressure can also reduce void formation, thereby improving interlayer bonding quality compared with conventional methods. In addition to processing conditions, adhesive elastic modulus and thickness, as well as surface roughness, affect delamination resistance. This review maps the relationship between vacuum lamination parameters, interlayer bonding quality, and ballistic performance, providing a basis for developing more reliable hybrid ballistic plates. The synthesis also highlights the importance of controlling bonding conditions to achieve consistent structural performance.
