Study of physical and mechanical properties of cellulosic and lignocellulosic nanofibers reinforced epoxy resin

We can enhance stress transmitting in adhesives using different fibers. So, the aim of this study was to investigate the potential of epoxy resin reinforcing using cellulosic and lignocellulosic nanofibers and compare their performance in improving of epoxy adhesives characteristics.
In this study, after applying the solvent exchange for better distribution of nanoparticles in epoxy resin matrix, the nanoparticles at three levels 0.1, 0.2 and 0.3 percent by weight epoxy resin was added to the matrix. The resulting mixture is then poured into film molds with a thickness of 4 mm and then tested after 72 hours.
The results showed that by increasing the nanofibers percentage to 0.2%, mechanical properties improved. But from 0.2 to 0.3% these features are reduced. Also, with increasing nanofibers physical properties decreased.
According to the study results it revealed that using small amounts of nanofibers (0.2%) mechanical properties of the composite increased approximately 2-times.
