“…Recently, some researchers tried to improve the mechanical and impact behavior of composite materials by addition of various nanoparticles such as nano clay and graphene as two-dimensional, carbon nanotube as one dimensional and fullerene as spherically with zero-dimensional geometries. In this regard, Sepetcioglu et al 30 studied the effect of graphene addition on fatigue behavior of basalt/epoxy composite pressure vessels. The results of this research demonstrated that the number of fatigue cycles of observed damages increased with the addition of a low content (0.25 wt.%) of GNPs.…”

Nanoparticles are considered as feasible strengthening agent which strengthen different types of polymeric materials with minor reduction in the density of composites. In this study, 0.1 and 0.5 wt. % Graphene Nano Platelets (GNPs) are added to the matrix of basalt fiber reinforced epoxy composites (BECs) and the effects of such addition on low velocity impact behavior are investigated. In this regard, the epoxy matrix is reinforced in macro scale by basalt fibers weaved together in 2/2 Twill pattern. Vacuum Assisted Resin Infusion Molding (VARIM) method is used to fabricate the pure and multi-scale BECs. The profile energy method is also used to evaluate the penetration and perforation threshold of fabricated pure and multi-scale BEC specimens. The force versus time and deflection, energy and deflection versus time curves are plotted and the key parameters of low velocity impact test including maximum force, energy and deflection are compared. According to the results, introducing of GNP nanoparticles in the matrix of BECs improves the low velocity impact behavior of these composites by increasing the contact force and decreasing the absorbed energy in rebounding state. Finally, based on the experiments, the 0.5 wt.% BEC has the best impact performance by applying 15.08 kN impact force against the applied forces of 13.78 kN and 11.208 kN for 0.1 wt.% and pure BECs.

“…As a result, analyses were performed for the dome and cylinder transition region in line with the experimental and numerical data, and the points to be considered in the pressure vessel designs were presented. Sepetcioglu et al [ 16 ] conducted experiments to assess the influence of graphene nanoplatelet additive on the fatigue performance for basalt fiber‐reinforced composite pressure vessels. In this context, tests were performed at load rates of 30%, 35%, 40%, 50% and 60% of the ultimate transverse stress at which leakage damage occurred, and damage occurrences were examined.…”

Hydraulic cylinders can reach enormous sizes depending on the working pressure and application areas. These structures, which are typically fabricated using traditional steels, can be quite heavy, which can cause a number of issues, particularly low system efficiency and fuel performance. A Type 1 composite hydraulic cylinder (CHC) with geodesic dome trajectories was created in our earlier work, and the effects of composite material utilization on the structural weight and mechanical responses were examined. Furthermore, the applicability of the geodesic dome to the CHCs was examined, and the benefits and drawbacks of using the dome profile were found. A Type 2 CHC was created in the current study, and the structural performances of Type 1 and Type 2 CHCs were compared. In this regard, numerical analyses were done to assess the mechanical responses and structural performance of a Type 2 CHC. Additionally, utilizing response surface methodology (RSM), the design parameters were optimized. The outputs of the current study were then verified by comparing the outcomes of statistical-based RSM and FEM examinations. As a result, the structural weights for both designs were compared with steel hydraulic cylinders of the same strength, and it was revealed that Type 1 and Type 2 CHCs were 53.78% and 38.42% lighter than steel ones, respectively. In addition, the advantages and disadvantages of the design types were discussed, and thus the optimum design was determined by considering the application areas and requirements.

“…Some design parameters such as stacking sequence, [16][17][18][19] fiber material, [20] fiber orientation [21] and nanomaterial additive [22] are significantly effective on the mechanical properties of the composite overwrapped pressure vessels and composite pipes. Therefore, many studies have been carried out to determine the effect of design parameters on mechanical properties.…”

“…Therefore, many studies have been carried out to determine the effect of design parameters on mechanical properties. [16][17][18][19][20][21][22] In the study conducted by Sharma et al, [23] FEM analyses for the composite pressure vessels with six different dome shapes as hemispherical, paraboloid, ellipsoid (I), ellipsoid (II), ellipsoid (III), and isotensoid were carried out, and effects of the dome shape on the burst pressure, failure characteristics and weight performance were examined. For each dome shape, mathematical models of the thickness along the dome were created depending on the dome height.…”

Hydraulic cylinders are used in many different areas from aviation to construction machinery and are generally manufactured using conventional steels that stand out with their low strength to weight ratio. In this study, it was aimed to design a hydraulic cylinder using composite materials to reduce cylinder weight. In this context, a novel composite hydraulic cylinder was designed, and numerical analyses for the composite portions of the hydraulic cylinder were carried out. For the numerical model, an aluminium liner and cylinder heads with the geodesic dome profiles were used, and composite layers were formed on their surfaces by using the Ansys ACP module.
