Abstract
In this research, the impact properties of epoxy biocomposites reinforced with nano cellulose and nano rosemary plant extract from Lorestan are investigated. The samples were made in 4 different weight percentages (pure, .5% by weight, 1% by weight, 1.5% by weight, 2% by weight) for uniform explanation and the quality of the construction was checked by scanning electron microscope. The results of this investigation show that the distribution of all types of nanoparticles is completely uniform up to 1.5% by weight, and after that, lumpiness of the particles is observed. In the next step, the samples are subjected to the Izod impact test, which obtains the most absorbed energy for all types of reinforcements in 1.5% by weight of nanoparticles, and after that, in the 2% by weight sample, this value significantly decreases. It starts to decrease. This trend can be due to the agglomeration of nanoparticles in epoxy, which has caused a decrease in mechanical properties. In the last step, in order to check the accuracy of the obtained results, for all types of samples of uniform distribution, modeling was done using the finite element method and with the help of software, and the modeling results were compared with the laboratory results.
