“…Fiber hybridization is one of the promising strategies to tailor the properties of composite materials [46]. Interply and intraply are two different fiber hybridization structures that are commonly used in the literature [28,47]. Interply fiber hybridization is based on the use of different fiber materials in different layers of composite laminate, while intraply fiber hybridization is based on the use of different fiber reinforcements in the same layer.…”

The current study aimed to examine an experimental investigation on the energy absorption capability of glass/carbon intraply hybrid filament wound composite pipes subjected to quasi-static lateral compression loading. The composite pipes with different fiber orientation angles were fabricated for both hybrid and non-hybrid to systematically analyze the performance of intraply hybridization process. At least 5 samples of each composite pipe configuration were tested to obtain the loaddisplacement curves and fracture patterns. The failure modes and fracture mechanisms of crushed samples were discussed to establish the influence of hybridization on crashworthiness parameters through load-displacement response. Separation between the layers (delamination) was occurred as the main damage mechanism in all samples. Hybridization with glass fiber significantly increased the energy absorption capability and load carrying capacity of carbon fiber-reinforced composite pipes. Their crushing values were found as between the values of pipes made of glass fiber and carbon fiber as expected. Furthermore, hybridization provided to opportunity of more stable load-displacement response for crushing process. An increment in fiber orientation angle was also led to increase in energy absorption capability and load carrying capacity. The pipe made of glass with higher fiber orientation had the best specific energy absorption.

“…Krack et al used the equation of stresses to verify the numerical tress results, and used as a constraint for the optimization design to calculate the maximum angular velocity [1]. Ha et al also considered the stress into the design optimization to calculate the optimum radii under the condition of the maximum angular velocity being fixed [10]. But, all the researchers did not use the stress equation for calculating the maximum angular velocity and the maximum outer radii simultaneously.…”

Considering the cost evaluation and the stress analysis, a fuzzy satisfactory optimization (FSO) method has been developed for a hybrid composite flywheel. To evaluate the cost, the cost coefficients of the flywheel components are obtained through calculating the weighted sum of the scores of the material manufacturability, the structure character, and the material price. To express the satisfactory degree of the energy, the cost, and the mass, the satisfactory functions are proposed by using the decline function and introducing a satisfactory coefficient. To imply the different significance of the objectives, the object weight coefficients are defined. Based on the stress analysis of composite material, the circumferential and radial stresses are considered into the optimization formulation. The simulations of the FSO method with different weight coefficients and storage energy density optimization (SEDO) method of a flywheel are contrasted. The analysis results show that the FSO method can satisfy different requirements of the designer and the FSO method with suitable weight coefficients can replace the SEDO method.
