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.

Abstract

Ultra High Molecular Weight Polyethylene (UHMWPE) is a polymer material widely used in ballistic protection systems due to its low density, high specific strength, and excellent energy absorption capability. This article aims to systematically review various UHMWPE reinforcement methods, compare their effectiveness, identify the most promising methods, and evaluate their effects on the mechanical properties and energy absorption performance of the material in ballistic protection applications. The method used is a systematic literature review following the PRISMA framework (Identification, Screening, Eligibility, and Inclusion). Literature was collected from the Scopus, ScienceDirect, Web of Science, and Springer databases in period 30 years. Of the 86 articles initially identified, 42 articles met the inclusion criteria and were analyzed descriptively and comparatively, covering crystallinity modification, gamma irradiation crosslinking, vitamin E stabilization, and the incorporation of reinforcing materials such as graphene, carbon nanotube, aramid, and carbon fiber. The results indicate that increased crystallinity and crosslink formation improve hardness, tensile strength, wear resistance, and structural stability under impact loading. The addition of vitamin E effectively inhibits oxidative degradation and improves fatigue resistance by approximately 30%, while nano-based fillers such as graphene nanoplatelets and carbon nanotubes significantly enhance mechanical strength and energy dissipation capability. Overall, the combination of gamma-irradiation crosslinking with nano-filler reinforcement shows the greatest potential for improving the performance of UHMWPE as a lightweight ballistic protection material with high energy absorption capability.
