Abstract

In this work the effect of adding SiO2 powder on the hardness property for UPE was studied. Three groups of samples were prepared (UPE/(SiO2-Micro)), (UPE/(Nano-SiO2) and (UPE/(Micro+Nano)SiO2) with weight fraction of additives (%2، %4، %6، %8). The surface hardness for all samples was measured before and after irradiation with Ultraviolet at time interval (10) hours. The experimental results showed that the surface hardness of all samples increases with increasing the weight fraction of SiO2 in the composite in natural conditions, and that the nano samples has higher hardness than other samples. After UV irradiation, the hardness values also increase with increasing the weight fraction of SiO2 in the composite for all samples, and their value is higher than in normal conditions.
