The curing process, wear behavior, and mechanical properties of an epoxy adhesive filled with boron carbide (B₄C) were studied. Two different particle sizes and amount of reinforcing B₄C were tested. One advantage of using B₄C is its ability to absorb neutrons, a property of great importance in the nuclear industry. Gel time and degree of curing were measured to evaluate the effect of adding B₄C to the epoxy resin. The chemical structure was studied by Fourier Transform Infrared Spectroscopy (FTIR) and the B₄C distribution was analyzed by laser confocal microscopy. Dynamic Mechanical Thermal Analysis (DMTA) tests were also carried out to monitor the viscoelastic properties and the glass transition temperature (T_g) of the cured reinforced epoxy. The wear resistance against alumina was measured using a pin-on-disc test, evaluated as mass loss. The wear tracks were studied by Scanning Electron Microscopy (SEM). The bending strength was also studied to assess the degree of interaction between the B₄C and the matrix. The results showed that the reinforced epoxy with B₄C was very abrasive, wearing the alumina. The reinforced epoxy had excellent mechanical properties that increased with B₄C content and with small particles. Moreover, the T_g value decreased slightly upon B₄C addition.
