The aim of this research is studying the effect of the fibers orientation on the reinforced aluminum specimens. The fibers are made of uniform carboin (0-90) of a volumetric fraction equal to 0.8%. This is for all the reinforcement fiber orientations, using Sikadur -300 resin as connection stuff. Three fiber orientations reinforcements have been used. These orientations are: circular, longitudinal and helical. Then twisting test has been carried out for all the specimens. The test proved that the circular reinforcement improves twisting property, and the helical orientation gives less improvement, while the longitudinal one gives no improvement in the twisting property.
