Synthesis and Experimental Characterization of a MWCNT-Filled Bio-Based Adhesive

In the present paper, a novel epichlorohydrin/cardanol adhesive was reinforced by multi-walled carbon nanotubes (MWCNTs) and characterized experimentally. The MWCNTs in weight ratios (wt %) of 0.5%, 1.0% 2.0%. bulk properties were through dynamic mechanical analysis tests, tension fracture toughness while its shear behavior single-lap tests on aluminum composite bonded specimens. morphology using scanning electron microscopy tests. Due to high viscosity bio-based adhesive, special efforts placed dispersion into which achieved mixing. results from show that presence increases glass transition temperature, Young’s modulus it decreases tensile strength. This contradictory finding is attributed formation MWCNT agglomerates adhesive. For content 2.0 wt %, strength increased 57% for joints 10.4% joints. findings study reveal reinforcement feasible manufacturing viewpoint may increase efficiency structural applications.
