Optimization of fatigue life in laminated composite plates

  • Bassam Ali Ahmed EMAIL logo


With the development of fiber technology on which the composite materials depend mainly was necessary to improve the rigidity, durability, and heat transfer in the areas of heating and cooling technologies. The effect of the fatigue phenomenon on composite materials using carbon fibers is studied. In this research paper, work was performed to study the improvement in the bearing capacity of the stress test sample with the addition of carbon fibers at different angles. The stresses affecting the test specimen are cylindrical with a length of 10 cm. The results proved that the best arrangement of the carbon fibers in the form of triple layers starting from the center of the cylinder circle to the outside was the share of the arrangement layer 45, 0, 0, where the lowest value was the number of fatigue life cycles, 2349 cycles in the bending test, as the amount of stress that this case reached was 6.1×108 Pa compared to the rest of the studied cases.
