“…When the interface strength and aspect ratio of the reinforcing particles are sufficiently high, such as in glassfiber reinforced polymers, fatigue life increases are generally seen when comparison with the non-reinforced polymer is made at the same stress amplitude, whereas decreases are seen when comparison is made at the same strain amplitude [28,29]. With a nanocomposite system similar to that of the present study, the same trends with respect to fatigue life were observed [30].…”

“…Previous studies on the effect of reinforcing semicrystalline polymers on the fatigue behavior indicated possible improvements on the crack growth resistance [24 -27] as well as on the fatigue life of non-notched specimens [28,29]. When the interface strength and aspect ratio of the reinforcing particles are sufficiently high, such as in glassfiber reinforced polymers, fatigue life increases are generally seen when comparison with the non-reinforced polymer is made at the same stress amplitude, whereas decreases are seen when comparison is made at the same strain amplitude [28,29].…”

Bulk fatigue damage evolution in polyamide-6 and in a polyamide-6 nanocomposite

et al. 2005

The mechanical response of a polyamide‐6 montmorillonite clay nanocomposite and of a polyamide‐6 was monitored during axial fatigue tests performed at R‐ratios of 0.1 and −1. For both materials, two transitions were usually observed in the evolution of all the stress‐strain‐time parameters studied after similar numbers of loading cycles, suggesting interrelationships between the mechanisms of molecular reorganization. Fatigue test monitoring indicated an initial decrease in the storage modulus and a subsequent trend for this modulus to increase, especially in polyamide‐6. During all tests, a partially recoverable strain was accumulated because of viscoelastic deformation. Nanoparticles reduced this strain in the initial cyclic straining regime but not in the last regime, probably because such particles cannot inhibit viscoelastic events constrained in a volume larger than their interaction volume within the matrix. Based on the accumulated volume variation measured, the nucleation and growth of microvoids can be expected to occur in the last cyclic straining regime. POLYM.

“…3a and b). Temperature changed in the whole specimen that means failure was in progress in the whole material as it was observed in previous studies [11][12][13][14]. The failure mechanism was too fast to reach a balanced state as Esmaelliou et al [14] reported.…”

“…To examine failure energy demands, the fracture surface of the composites was investigated by SEM. This investigation follows the failure mechanism described by Horst et al [11]. Firstly, the cracks appear at the end of fibers because they are stress concentration points, then the crack grows along fibers, and finally these areas of failure connect to each other and create voids.…”

“…These composites usually suffer fatigue load, that is why it is important to investigate the fatigue properties of a new type of composite. More and more researchers assume that not just the fatigue life of a material is important but also the failure process itself, therefore researchers pay more attention to the investigation of fatigue crack propagation and failure analysis [9][10][11][12][13][14]. Esmaelliou et al [14] investigated the fatigue properties of glass fiber reinforced polyamide 66, where the load factor which is the ratio of minimal and maximal stress was 0.1 and frequency was 20 Hz.…”

In this study the effect of basalt and carbon fiber content on IntroductionPerformance improvement is one of the most important criteria when a novel polymer composite is developed for engineering applications. For the optimal mechanical performance of materials composite industry uses several types of reinforcing materials [1]. The popularity of glass fibers is unbroken, but nowadays carbon fiber is gathering ground, thanks to its decreasing price and well known good mechanical properties [2][3][4]. Another competitor is basalt fiber. Its composition is close to glass fiber, but this eruptive rock has less complex structure, its thermal and chemical resistance is much better and production is simpler compared to widely used E-glass fiber [5,6]. As well as glass fibers basalt fibers appeared not only as reinforcement of polymer matrices but also in concretes [7,8].Because of the high performance and the mass production the fiber reinforced plastics are becoming increasingly popular in the automotive industry. These composites usually suffer fatigue load, that is why it is important to investigate the fatigue properties of a new type of composite. More and more researchers assume that not just the fatigue life of a material is important but also the failure process itself, therefore researchers pay more attention to the investigation of fatigue crack propagation and failure analysis [9][10][11][12][13][14]. Esmaelliou et al. [14] investigated the fatigue properties of glass fiber reinforced polyamide 66, where the load factor which is the ratio of minimal and maximal stress was 0.1 and frequency was 20 Hz. They showed that the fatigue process during loading of polyamide 66 can be divided into three parts. In the first part the relative Young's modulus decreases intensively and temperature increases gradually. Then in the second part, both the temperature and the relative modulus are approximately constant. The third part begins typically when 75% of the number of cycles that belongs to failure is reached. In this part temperature increases and relative modulus decreases again until failure. At higher load levels the second and the third part become less remarkable and gradually disappear by further load increment.There are only a few publication that deals with the investigation of fatigue properties of injection molded thermoplastic
