Abstract

The creep test is one of the important approaches to determining some mechanical properties of composite materials. This study was carried out to investigate the creep behaviour of an epoxy composite material that was reinforced with Y<sub>2</sub>O<sub>3</sub> powder at weight ratios of <i>2</i>%, <i>7</i>%, <i>12</i>%, <i>17</i>% and <i>22</i>%. Each volume ratio was subjected to five loads over the range of <i>1N</i> to<i>5N</i> at a constant temperature of <i>16 ± 2°C</i>. In this work, creep behaviour, stress and elasticity modulus were studied through experimental and numerical analyses. Results showed that increasing the weight ratio of Y<sub>2</sub>O<sub>3</sub> powder enhanced creep characteristics.
