“…Yashiro et al 26 investigated the damage characteristics of a 2D woven composite at elevated temperatures by conducting high‐speed impact, thermal‐explosion, and thermal‐shock tests successively, suggesting that the operating temperature was one of the most important parameters that impacts resistance. Coles et al 27 tested the resultant ballistic dynamic response of a T300 woven composite in a flat‐plate shape by applying a noninvasive analysis technique. It was proven that the solid projectiles led to increasing localized deformation and even penetration, whereas the destroyed fragmenting projectiles led to homogeneously distributed impact load, causing the major front‐surface damage that depended on the depth of indentation.…”

Considerable research has indicated that fiber‐reinforced textile composites are significantly beneficial to the aerospace industry, especially aero engines, due to their high specific strength, specific stiffness, corrosion resistance, and fatigue resistance. However, damage caused by high‐velocity impacts is a critical limitation factor in a wide range of applications. This paper presents an overview of the development, material characterizations, and applications of fiber‐reinforced textile composites for aero engines. These textile composites are classified into four categories including two‐dimensional (2D) woven composites, 2D braided composites, 3D woven composites, and 3D braided composites. The complex damage mechanisms of these composite materials due to high‐velocity impacts are discussed in detail as well.

“…Upon transition to the final stage of the exhaustion of the resource -fragmentation, a decrease in the load capacity occurs abruptly with following destruction of the specimen. It should be understood that in view of the variety of structures of composite materials, the mechanisms of their destruction must be investigated separately for layered [1][2][3][4]10], 2-D and 3-D woven [5][6][7][8][12][13][14] materials, as well as for materials reinforced with short randomly directed fiber [17][18][19][20]. Nowadays the damage assessment with the X-ray and computer micro tomography methods has become widespread [15,16,18], but at this stage of development of these technologies, their application is impossible directly in the testing process.…”

The use of polymer composite materials for highly loaded structures in modern engineering is constantly expanding, since they have high specific strength characteristics under static loading. However, the question of providing the required resource of such materials under cyclic loading remains open. In this work, we propose an experimental technique for assessing the damageability of specimens of layered polymeric material during fatigue tests. Criteria, which can indicate the appearance of interlayer fracture in the tested specimens, are given. A correlation between the appearance of a new spot of interlayer destruction in the specimens and a decrease in a number of acoustic emission events per unit time, during fatigue tests, were revealed.

“…However, the use of CFRP in the GTE structure is still hampered not only by the high cost of designing and manufacturing parts and assemblies, but also by the high cost of manufacturing samples for many different kinds of mechanical tests. During such tests, the static stress limit, the fatigue limit, the resistance to ballistic and impact damage etc [3] are determined. All these properties are used to identify and adjust the GTE parts and assemblies calculation models [4].…”

The carbon fiber reinforced polymer composite are widely used in industry as major structural materials. They represent the greatest interest for the production of gas turbine engines parts because of their high specific strength. But before adaptation these materials into the structure, it is necessary to conduct a number of tests, both on test coupon and on structurally equivalent samples for determining physical, in particular, fatigue properties of these materials. However, the high cost of manufacturing coupons for such tests has a negative impact on the adaptation of carbon fiber reinforced polymer composite into the composition of final products. In this paper it is presented a method for fatigue tests of test coupon and structurally equivalent samples of carbon fiber reinforced polymer, aimed at reducing the consumption of coupons which are necessary for obtaining fatigue properties. Based on the developed method, a series of carbon fiber coupons was tested and the fatigue limit was obtained. At the same time, the use of coupons was minimized.
