Creep Properties of Particles Materials Reinforced Epoxy Composites


Composites were prepared from epoxy and particles fillers of copper, aluminum and calcium carbonate. Added effect has been studied to creep properties at room temperature and load 12.26 MPa. Properties that include creeping studied , primary creep, creep rate , the time of the fracture, exponential factor and activation energy, found that the addition of calcium carbonate particles to reduce the creep rate (0.0011) compared to epoxy, also more than doubled the time of the fracture , while primary aluminum particles than to creep in to a (0.1). Except imbricated epoxy / calcium carbonate , all materials tend to behave in a manner flexible exponential factor where it is located with in the range (0.26 – 0.38). Finally , all the filling had improved the activation energy results.Particles of copper, aluminum and carbonated calcium filled epoxy for composites were prepared. The effect of addition on the creep properties of composites was assessed at room temperature and (12.26 MPa) loading. Creep properties that studied included: initial creep, creep rate, time to rapture, exponent factor, and activation energy. It is found that added carbonated calcium particles reduced the creep rate to (0.0011) comparing to epoxy and increased the rupture time to more twice times, while aluminum increased the initial creep strain to be (0.1). Except epoxy/CaCO3 materials tend to behave in elastic manner where their exponent factor lies within range (0.26-0.38). Finally fillers enhanced the activation energy results.
