“…Thomas et al investigated an analytical and finite element modeling, with experimental validation of the bending strain and deflection of an epoxy E-glass fiber composite laminate with distributed MFC actuator patches [28]. Glukhikh et al employed built-in deformation MFC actuators to control twisting of a helicopter blade for reducing its vibration and noise [29].…”

Active pointing compensation of a High Throughput Satellite (HTS) multibeam antenna via microfiber composites (MFCs) is studied in this paper. Electrical-mechanical coupling analysis of MFCs is conducted to quantitatively determine driving forces and moments of MFCs attached on a carbon fiber reinforced composite (CFRP) laminate, and a positive correlation relationship is observed for driving ability versus thickness of the laminate. By different driving strategies, MFCs could act in bending mode and torsioning mode for structural deformation control, and driving efficiency of the MFCs on a multibeam antenna is studied. Thermal distortion of the antenna under a typical in orbit thermal distribution causes the reflector to rotate about y axis with an pointing error of 0.005°, active compensation is conducted, and the final compensation results show that with an optimal voltage of 432 V, pointing error of the antenna is greatly compensated, and the depointing angle is corrected to be 0.00004°.

“…The problem of introducing piezoactuators into a structure remains unresolved. The introduction of a foreign body inside a layered composite structure can lead to a decrease in the strength of the structure, up to its destruction [3,4]. To solve this problem, it is necessary to conduct a complex of computational studies aimed at developing new approaches and mathematical models of composite materials with piezoactive structural elements (piezocomposites).…”

In this research we developed a technique for calculating the stress-strain state of a model construction from a thermoplastic composite material with an embedded piezoactuator. Numerical simulations of the model construction stress-strain state with different arrangement of piezoactuators: upper and middle,-were performed. Numerical simulations were carried out in a three-dimensional setting taking into account the complete technological scheme of laying and anisotropy of the properties of reinforcing layers. The results of numerical experiments revealed the areas of maximum stress. Recommendations for the MFC’s embedding into composite materials were formulated.

“…For these reasons active control is deemed to te a promising technology for the design of new high performing blades [12,13]. Because piezoelectric materials have a series of desirable characteristics, such as self-sensing, structure embeddability, fast response and covering a broad range of frequency, they are often proposed for the design of active blades [14,15,16]. In order to overcome the drawbacks of the typical piezoceramic actuator, such as the vulnerable ability to damage and the fact that they can hardly conform to a curved surface, piezo-composite actuators, e.g., Active Fiber Composite (AFC) [17] and Macro-Fiber Composite (MFC) [18] were developed.…”
