| Abstract | ||
| In this study, torsion test was performed in order to examine the mechanical behaviors of epoxyand an epoxy reinforced by two types of glass fibers (chopped and yarn) composite rod. The stressstraincurves were constituted and examined in order to show the elastic and plastic regions, theyield point was 23.226o and 34.837o angle of twist for epoxy and epoxy /fibers respectively whichis the same for both chopped and yarn glass fibers epoxy, from this test it was found that the epoxyrod initially yielded first, the cracks propagation in composite rod along the fibers direction, whichcaused eventually the delimitation of composite chopped and yarn glass fibers from the epoxymatrix. Then the white regions appear in composite rod and finally the fiber breakage and thecatastrophic failure took place. | ||
