“…Results revealed that nanoclay and glass fibre weight parentage have positive effect on mechanical properties of composites, whereas hygrothermal aging conditions (cold and boiling soaking) have negative effect. 31–34 Singh SP et al (2022) has studied the effect of environmental degradation and mechanical behaviour of glass fibre reinforced polymer nanocomposites used in offshore applications. He examined that at 0° orientation, maximum average flexural strength of 295.04 and 481.69 MPa was observed for plain glass fibre reinfoced polymer and 2% nanoclay/glass fibre reinfoced polymer before hygrothermal loading.…”

“…Figure 10 shows the thermal stability of various specimens loaded at different weight percentage of clay was well observed by TGA analysis. Different specimens exposed at various loading level are represented by different codes such as 24,26,34,36,54, 56 and pe. '24' are read as 2.0 wt.% of clay at 4 hrs of post ultrasonification and so on.…”

In many industrial applications elastomers are frequently used due to its low cost. In present study the Ethylene propylene diene elastomer (EPDM) was used. Solution intercalation method adopted to synthesize EPDM/OMMT clay nanocomposites using organically modified montmrillonite clay. At different loading levels of clay (2%, 3% and 5% weight) various characterizations such as tensile strength, flexural strength and d-spacing behaviour were performed. X-ray diffraction technique was used to study the d-spacing behaviour of different nanocomposites at 2%, 3% and 5% weight percentage of clay loading level. Clay dispersion in the rubber matrix was observed by scanning electron microscope. Comparative study between pure EPDM specimen and EPDM clay nanocomposite specimen was carried out. Modulus as well as flexural strength value was higher for EPDM clay specimen as compared to pure EPDM specimen.

“…In the literature, various studies investigate the tangential tensile strength of various composite materials with cylindrical geometry. [9][10][11][12] Sepetçioglu et al (2021) aged the graphene nanoplatelet doped basalt fiber reinforced epoxy composite pipe samples at 80°C in the pure water. As a result of the study, they observed significant losses in mechanical properties such as density, hardness and hoop tensile strength of the samples.…”

Composite materials are becoming widespread in many sectors today, especially in the defence and space industry. Composite materials can be exposed to significant temperature changes and various environmental conditions depending on their usage areas. Therefore, composite materials with high resistance to high temperatures and harsh environmental conditions are being studied today. In this study, four types of 6-layer composite pipes with glass/glass/glass, basalt/basalt/basalt, glass/basalt/glass and basalt/glass/basalt stacking sequences were fabricated with filament wound method. In order to simulate the behavior of composite materials under environmental conditions, specimens were subjected to hydrothermal aging in pure water at 70°C for three different periods of 500, 1000 and 1500 hours. During the aging process, the mass changes of the pipes were measured regularly, and the water absorption behavior was determined with reference to ASTM D5229 standard. Hardness tests were carried out with Rockwell hardness tester based on ASTM D785 standard. As a result of the study, it was determined that the mechanical performance of hybrid specimens was higher than that of non-hybrid specimens. It was observed that the hydrothermal aging process caused a loss of mechanical strength in all specimens. It was concluded that the hybrid composite specimen with basalt/glass/basalt stacking order had the highest resistance to hydrothermal aging.

“…Xu et al [2] highlighted that both temperature and moisture contents significantly influence the fatigue properties of carbon fibre cross-ply laminates. Besides, Rafiee et al [3] analysed the combined effect of hygrothermal loads and sustained mechanical loads on the strength of an E-glass/Epoxy composite. Their work showed that preloading has no significant effect on moisture absorption behaviour.…”

This contribution deals with the development of a numerical approach based on Discrete Element Method to study the hygrothermal behaviour of conventional and composite materials. For this purpose, we consider the context of magnesium aluminate and polyamide 6 reinforced with 30% of short glass ﬁbre respectively. A coupled hygrothermal model based on boundary layer theory and the analogy between the Fickian mass and heat transfers is proposed. Besides, the original Halo approach introduced in the framework of heat conduction is adapted to determine water concentration gradient ﬁelds with a suitable level of description. The proposed model is validated in terms of water concentration and water gradient ﬁelds for both materials by comparison with numerical and experimental results through the modelling of drying and absorption processes. Results exhibit the relevance of the proposed approach to provide such an information with a suitable level of precision.
