“…The interested reader also referred to a review article in [49] discussed various works on the inclusion model. Despite the fact that the multiphase piezoelectric provide better multifunctional capability [29,50], the implementation of energy harvesting structure is not found in the literature. In the present work, for the first time, the multiphase piezoelectric composite is applied to the energy harvesting structure.…”

The multiphase composite with active structural fiber (ASF) has proven able to provide better optimization between actuating and load bearing capability compared to a pure piezoelectric material. In this paper, the multiphase composite application is further extended for energy harvesting purpose. The Double-Inclusion model combined with Mori-Tanaka method is implemented in a computational code to estimate the effective electro-elastic properties of the multiphase composite. The effective composite properties obtained via the present code are in good agreement with the analytical, experimental and finite element results. The multiphase composite with different composition is applied to a typical jet aircraft wingbox with 14.5 m halfspan. The energy harvesting evaluation by means of hybrid FEM/analytical piezoelectric energy harvester model is presented. A new procedure to investigate the trade-off between the aircraft weight, the fuel saving and the energy harvested is developed. The results pointed out that the equivalent fuel saved from the power generated by the wingbox is more than enough for 1 hour Auxiliary Power Unit (APU) operation.

In this paper, a novel iterative finite element method (FEM) for energy harvesting purpose is presented. The new iterative FEM is implemented to solve the dynamic problems of piezoelectric-based energy harvester in the frequency and time domains. The validation against other methods from the literature shows the robustness and capabilities of the iterative FEM. Implementation to a transport aircraft wingbox with 14.5 m half span and an embedded piezoelectric layer is shown in some details. The energy harvesting potential of the wingbox due to the cruise and the 1-cosine gust loads is investigated. In addition, for the first time, stress and failure analyses of the structure with an active energy harvesting layer are performed. The results pointed out that the wingbox is still in a safe condition even when it is subjected to a 30 m/s gust amplitude while harvesting 51 kW power.

“…Carbon nanotubes (CNT) can be added as a means to provide multifunctionality to CFRP materials for aerospace structures, because of their unique physical, thermal, and optical properties [11][12][13][14]. When transferred efficiently to the composite, they are expected to provide mechanical improvements (strength, stiffness, interlaminar shear strength) and enhance the thermal and electrical properties [15,16]. Chen and Rabin [17] showed that it is possible to produce epoxy/CNT composites with surface optical quality to be used as mirrors using the replica method.…”

Fiber print-through effect is a limitation to the use of carbon fiber-reinforced composites in space applications, namely, mirror telescopes. Replica method is used for the production of lightweight telescope mirrors. However, this method requires a polished mandrel, increasing considerably the final cost. In this work, we report a cheaper and simpler alternative production method, which consists in the addition of a carbon nanotube filled epoxy resin layer on the surface of carbon reinforced composites, in order to reduce fiber print-through of the materials. The influence of different carbon nanotube functionalizations, concentrations, and dispersion levels are also assessed. The surface properties are evaluated by interferometry (roughness and waviness) and scanning electron microscopy (morphology). The results show that the waviness, roughness, and consequently fiber print-though are considerably reduced with the addition of a thin layer of nonfunctionalized carbon nanotubes.
