| Abstract | ||
| :This research include the study of the fatigue property for the polymer and the composite materials, we using the epoxy resin as matrix for the reinforced materials that consist of artificial fibers (Kevlar, glass and PVC fibers) also aluminum powder for reinforcing. The slates made of composite materials and hybrid composite materials for both volume fractions30% and 40% from the reinforced materials, where we made twenty one slates from the composite materials, all these slates cutting to samples with measurement (10x 70mm) in order to execute the fatigue test accordingly for the fatigue machine characteristics, these samples divided to several groups for both volume fractions 30% and 40%, these groups immersing in H2SO4 acid for fifty day to study the effect of this solution in the fatigue characteristic. The test executed by two steps: - the first step include executing the fatigue testing for the dry samples and comparison these results with each other, the second step include the fatigue test for the samples after immersion in the solution (H2SO4 acid) for fifty day,. The results of fatigue test from the second step comparing with the results from the first group for both volume fractions 30% and 40%. The results and laboratory examinations for these samples show a decreasing in the number of fatigue cycles until the fail when the applied load or applied stress increase | ||
