Abstract

The objective of the present work was to analyze the fatigue resistance and to propose actions to prevent fatigue failure of industrially manufactured composite laminates used in the production of coal reservoirs. These materials are made of polyester resin reinforced with E-glass fibers. Two stacking sequences consisted of mats and (bi-direction) woven fabric textile were studied. Tensile and compressive mechanical tests were also performed. Next, the fatigue behavior of the composites was investigated. Tensile (R = 0.1), compressive (R = 10), and alternate axial fatigue (R = -1) tests were carried out varying the maximum tensile stress. The results were used to plot S-N curves as well as to propose Modified Goodman Diagrams for failure prevention. The study revealed the effect of different processing parameters on the fatigue behavior of laminates.
