“…This kind of phenomenon was also described by [5,9]. In a previous work [12], this damage zone was identified as a through-the-thickness crack all along by microscopic investigations. Since the beginning of the crack growth, this damage zone has presented tows breakage even in the tip.…”

“…Earlier experiments [12] showed a different behaviour between warp and weft directions of the studied balanced woven ply under static loading as well as in fatigue, especially in crack propagation tests in samples of 30 mm width (Fig. 4).…”

“…It can be noted on this figure, the six warp and weft samples are exactly the same, only the initial crack tip position relative to the yarns should be different (this manufacturing parameter is difficult to control). These differences have been connected to the crack initiation time [12] which depends on the sollicitation direction and on the initial crack tip position relative to the yarns position. In fact, more the initiation time is long, more the crack growth decreases because of the extended of the damage zone.…”

“…This phenomenon is associated with the microstructure influence on crack growth [3,4]. Bizeul et al [12] stated that crack growth evolves regularly when three to five tows are broken. In other words, as the yarn width is equal to 0.5 mm, microstructure influence seems to exist when the crack length is less than 3 mm.…”

a b s t r a c tHelicopter blades are made of composite materials mainly loaded in fatigue and have normally relatively thin skins. A through-the-thickness crack could appear in these skins. The aim of this study is to characterize the through-the-thickness crack propagation due to fatigue in thin woven glass fabric laminates. A technological test specimen is developed to get closer to the real loading conditions acting on these structures. An experimental campaign is undertaken which allows evaluating crack growth rates in several laminates. The crack path is linked through microscopic investigations to specify damage in woven plies. Crack initiation duration influence on experimental results is also underlined.

“…Although the scatter was large, a Paris-Erdogan crack evolution law, based on the effective stress intensity factor range, was fitted to the data for long cracks. Bizeul, Bouvet, Barrau, and Cuenca (2010, 2011a, 2011b) also tested single-edge notched specimens made of 8-harness satin weave glass/epoxy composites in straincontrolled fatigue. At the opposite edge of the notch, a UD carbon strip was applied to mimic the loading condition of a composite skin in aeronautical structures.…”

Composite materials have emerged as an effective substitute for conventional materials in various fields of engineering and structural science. For replacement of regular metals, composites, especially fiber‐reinforced polymer composites, have proved to be a suitable alternative. One of the important tests that conventional and composite materials have to undergo is fatigue test. It refers to the testing of materials for their cyclic behavior. In fatigue testing, depending on the choice of the researchers, materials are loaded till reaching their failure or till reaching a fraction of the total stiffness loss. Composite materials are different from metals and they show a distinct behavior under fatigue loading. In metals, failure occurs from the commencement of a single crack and then its propagation. In composite materials, conversely, it is a complex process as these materials possess crack‐arresting properties. This review paper highlights various aspects of the cyclic or fatigue behavior in composite materials. Factors triggering such behavior in composite materials include reinforcing substance, matrix material, fiber orientation or stacking sequence, fiber content, testing environment and so on, together with the damage development process at the microscopic level. Loading condition parameters pertain to stress ratio, mean stress, loading condition, multiaxial stress, and testing frequency. This article also includes the effect of carbon nanotubes on the fatigue life of the polymer composites. POLYM. COMPOS., 39:1785–1808, 2018. © 2016 Society of Plastics Engineers
