The current focus in armor development is on the creation of lightweight, thin, and cost-effective solutions. This study explores innovative techniques by incorporating nanomaterials into composite plates, combined with fiber pre-stressing methods during the polymer matrix curing process. Woven Kevlar fibers experienced a pre-stress of 2 MPa in two dimensions while being cured with an epoxy resin containing varying ratios of Nanographene (0.5, 1, and 2 wt.%). Results demonstrated that the optimal combination for enhanced mechanical properties, particularly impact strength, occurred with a 2 wt.% nanographene ratio and 2 MPa fiber pre-stressing. However, exceeding a 2 wt.% nanographene ratio led to nanoparticle agglomeration within the resin, negating their positive effects. The proposed armor model successfully passed ballistic testing and comprises four layers of composite plates, each layer consisting of epoxy resin with 2 wt.% nanographene, Kevlar fibers pre-stressed at 2 MPa, and a 3mm thickness. These layers are interspersed with additional 1mm layers of Kevlar fiber. This innovative approach offers a promising advancement in armor design, achieving a balance between low density, reduced thickness, and cost-effectiveness.
