Abstract
In recent years, with increasing engineering applications, structural adhesives have played an increasingly important role in joining both metallic and non-metallic components. Polyurethane is frequently used in the adhesive industry due to its morphological structure, versatile material, and excellent matrix material. In addition, by doping polyurethane with single/multi-walled carbon nanotubes and boron nitride nanoplates materials, the mechanical properties of the polyurethane adhesive can be further increased. This study aimed to increase the mechanical properties of PU (thermoset polyurethane), which is frequently used in adhesively bonded joints by addition of MWCNT (multi-walled carbon nanotubes), BNNP (boron nitride nanoplates). For this purpose, nanoparticles synergistic interaction was investigated by adding a mass of 0.25%, 0.35%, and 0.45% MWCNT into PU, which was reinforced by 0.5% BNNP before. Samples mechanical properties were determined by tensile test according to ASTM D638-10 standard, flexure test according to ASTM D790-02 standard, and Shore D test according to ASTM D2240 standard. All sample test results were graphed, and each graph was compared. Also, broken surfaces were analyzed by scanning electron microscopy (SEM) to examine the damage mechanism of nanoparticles.
