Many engineering applications are made of boron carbide as a material that includes a unique combination of properties. One of the main properties of boron carbide is that it has thermal stability and a high melting point which makes it the perfect choice for refractory application. It also has a high abrasion resistance which makes it a good abrasive powder. The low density and high hardness properties are relevant for boron carbide to be excelled in ballistic performance It is frequently utilized in nuclear-based applications like that of a neutron absorber. Additionally, a high-temperature semiconductor namely, boron carbide could be utilized for wide electronic applications. Boron carbide (B4C)-filled epoxy glue mechanical characteristics were investigated. Two distinct B4C particle sizes and quantities were evaluated. The capacity of B4C to absorb neutrons is a significant attribute in the nuclear industry and represents one of the material's advantages. To evaluate the degree of interaction between matrix and B4C, the bending strength was also investigated. The structural instability phenomenon of boron carbide under externally induced high stresses and the characteristics of the resultant disordered phase are also explored. The volume fraction of filler components in the composite was adjusted, and good wear resistance and other mechanical characteristics were produced from nano-filled glass-epoxy. All the weight % composite samples are assessed for their tensile strength. The tensile strength of base metal has been enhanced with the addition of fiberglass and nano boron carbide/epoxy.
