The effect of angle reinforcing of composite material bars (polymer)‎ by cellulose acetate fiber on its strength for fatigue stress

الملخص EN

Study on oblique angle of composite material bar by reinforcing with acetate fiber was conducted to estimate the stress strength at fatigue test, by using rotary bending tester.

The specimens were used with 130mm length and 10mm diameter, which consist the basic material (Resin) and harder with oblique angles of (0°, 30°, 45°, 60°, and 90°), the cellulose acetate fiber has used with elastic mechanical properties.

The results were converged with practical and theoretical result for the number of failure and the values of correction factor, as well as the values of fatigue strength were between (28-100 Mpa) and had directly proportional with vertical compounds material, while the maximum value of oblique angle was equal to zero.
