Kevlar fiber and brass wire mesh reinforced with cubic boron nitride (CBN) particle-toughened epoxy composites are investigated in this study. This study aims to determine the hybrid composite's mechanical and drop load impact behavior, as well as the effect of surface treatment on the lamina delamination resistance and load bearing phenomenon. The composite laminates were fabricated by hand layup process and characterized according to ASTM standards. The tensile, flexural, Izod impact, ILSS, and hardness testing results shows that adding 35 vol% reinforcements and 3.0 vol% CBN particles indicates the greatest research findings. However, when the stacking sequences B/K/K/B and K/B/B/K were modified from B/K/B/K, these values reduced. The EO2 composite shows improved results in mechanical and drop load impact behavior together with Kevlar fiber and brass wire mesh of alternating staking sequences with 3.0 vol% CBN particles. It is clear that B/K/B/K stacking sequence shows the highest mechanical properties and drop load impact behavior while, B/K/K/B shows lowest values. This hybrid composite with higher mechanical qualities and impact energy absorption might be used in defense armors, aerospace, structural, automobile, and household equipment manufacturing applications.

硅烷化堆叠 Kevlar 纤维/黄铜 270 丝网对立方氮化硼-环氧树脂复合材料力学和冲击韧性的影响
本研究研究了用立方氮化硼 (CBN) 颗粒增韧环氧树脂复合材料增强的凯夫拉纤维和黄铜丝网。本研究旨在确定混合复合材料的机械和跌落载荷冲击行为，以及表面处理对层板抗分层性和承载现象的影响。复合层压板通过手工铺层工艺制造，并根据 ASTM 标准进行表征。拉伸、弯曲、悬臂梁冲击、ILSS 和硬度测试结果表明，添加 35 vol% 的增强材料和 3.0 vol% 的 CBN 颗粒表明了最大的研究成果。然而，当堆叠序列 B/K/K/B 和 K/B/B/K 从 B/K/B/K 修改时，这些值降低。EO2 复合材料与具有 3.0 vol% CBN 颗粒的交替铆接顺序的 Kevlar 纤维和黄铜丝网一起显示出改善的机械和跌落载荷冲击性能。很明显，B/K/B/K 堆叠顺序显示出最高的机械性能和跌落载荷冲击行为，而 B/K/K/B 显示出最低值。这种具有更高机械质量和冲击能量吸收的混合复合材料可用于国防装甲、航空航天、结构、汽车和家用设备制造应用。
