Abstract
Isochronous stress-strain relationships and long term creep performanc e for unfilled and hydroxyapatite filled polyethylene composites have been studied. The tests were carried out in a buffered (pH =7.5) Ringe r's solution at 37 degrees C. It was observed that the inclusion of hy droxyapatite does not remove the non-linear viscoelasticity of polyeth ylene. The creep resistance is found to increase with increase in volu me fraction of hydroxyapatite. The creep failure of composites at long times can occur due to debonding of the interface.
