“…Based on present technical knowledge, it is known that some material failures such as matrix cracking, swelling, fiber pull-out and delamination may occur due to the anisotropic and heterogeneous nature of the composite parts during drilling. [36][37][38] On the other side, the surface quality of the holes plays also a crucial role in the flawless and correct assembly of the final products. [39] Therefore, delamination on hole surfaces can be considered one of the critical subjects that should be taken into account during the drilling of composite materials as addressed in many literature efforts.…”

Among the various renewable energy sources, wind energy offers an effective solution to the energy providers. Onshore wind turbines are generally designed for sites with low wind resources, while offshore wind turbines can be more efficient in producing energy thanks to their longer blades that provide more than 10 MW of rated power. Offshore wind turbine blades are subjected to significantly higher stresses and harsh environmental conditions. Therefore, hybrid composites composed of carbon and glass fibers can offer cost-effective and long-lasting solutions for wind turbine blade manufacturers. Turbine blades are connected with main spars through bolted connections and high interlaminar stresses occurring during the drilling process can cause to delamination in the composites. To prevent catastrophic failure related to defective machining, the drilling process must be performed meticulously and all machining-related results must be analyzed step by step. In this paper, dry drilling properties of hybrid glass-carbon fiber laminate epoxy matrix composites were examined experimentally in order to contribute to the wind energy sector. The results showed that the delamination factor could be decreased with higher cutting speeds or lower feed rates. Besides, higher feed levels caused higher thrust forces on the tool body.

“…For that reason, many studies have been conducted to determine the optimum design parameters and thus improve the mechanical and dynamic properties of composite materials. [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34] Reguera and Cortinez [20] performed an optimization study to maximize the critical buckling load and minimize the weight of thin-walled composite beams. Qiu and Zhu [21] used the genetic algorithm to optimize the fiber orientations of composite beams under compression loads.…”

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.

Fiber orientation deviation is a typical defect type in carbon fiber reinforced polymer composites (CFRPs) manufacturing process. Unlike other defect types, fiber orientation deviation has minimal influence on the local conductivity of CFRPs, so it is difficult to be detected by eddy current (EC) detection methods. Based on the principle of eddy‐current equilibrium, a new method is proposed in this paper to improve the sensitivity of fiber orientation detection. In this method, an EC field with eddy‐current equilibrium distribution inside the specimen is excited by means of a special double D‐shaped probe. When there is a deviation from the fiber orientation, the eddy‐current equilibrium state is broken, resulting in a rapid increase in the intensity and distribution range of the induced EC inside the specimen, and finally lead to a drastic change in the probe signal. The experimental results show that the double D‐shaped probe with an eddy‐current equilibrium effect can detect the fiber orientation of CFRPs, and the changes in fiber orientation can cause up to a 423.1% variation in the probe signal. Compared with the traditional rectangular probe, the designed probe is more sensitive than the former to small changes in fiber orientation in the range of −20° to 20° under high frequency excitation above 3 MHz. In addition, the proposed method can also be used for rapidly identifying fiber waviness with a deviation angle of 7.4° inside unidirectional CFRPs, which can be achieved effectively and intuitively through defect imaging.
