Effect of silanized stacked Kevlar fiber/brass 270 wire mesh on mechanical and impact toughness of cubic boron nitride–epoxy composite

摘要

Abstract 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.
