Abstract
Abstract: The behavior of alumina - oxide based fibers reinforcements for high temperature application composite materials . These fibers suffered from a process of grain growth fabrication process and that lead to a great change of the properties of fibers . To study these effects , we examine a commercially available ( alumina ) and ( alumina - silica ) fibers which heat treated at various temperature as annealing at 1100,1300 oC , for up to 100 hrs changes of the fiber tensile creep stress rupture with the microstructure changes together with the heat treatment was shown to be of a significant effect , especially on the alumina fiber and shows a good creep behavior ( creep resistance ) .
