“…In this approach electronic circuits are assembled using traditional PCB technologies. These integrated PCBs are then installed on the inner face or inside dedicated cavities within platforms [136]. The fundamental problem with this type of integration is maintaining stiffness and the load-bearing properties of a modified aircraft skin structure.…”

Multifunctional composite structures (MFCS) have become an increasingly important field of research with the large-scale adoption of composite materials in many industrial sectors such as aerospace, automotive, sport and recreation equipment (bikes, scooters, etc.) and maritime. It is a diverse field which includes scientific areas in electromagnetics, electronics, material sciences, structures and structural augmentation, sensors, and thermal management. The paper investigates Conformal Load-bearing Smart Skins (CLSS) as a part of multifunctional composite structures specifically related to aerospace applications and focuses on the seamless incorporation and synergistic coexistence between electronic devices and composite materials. Current trends in materials and manufacturing processes, as well as measurement techniques used to validate both the electromagnetic and structural responses have been explored and discussed. Furthermore, it identifies some of the challenges and complexities associated with CLSS and explores future areas of research which still need to be addressed.

Simultaneously considering the absorption performance and load-bearing capability is a trend in the design of multifunctional structures. Nevertheless, the collaborative design and optimization involved in this process present a challenging problem. Herein, guided by multifunctionality, a lightweight microwave-absorbing/load-bearing multifunctional structure is intelligently inversely designed based on machine learning. A co-design scheme is developed to address the contradiction between the absorption performance and load-bearing performance. An approach for rapid inverse design of metamaterial absorbers containing multilayered frequency-selective surfaces (FSSs) is proposed. The simulation results obtained using multi-objective optimization based on surrogate models indicate that the optimized multifunctional structure achieves more than 90% absorption in the frequency range of 2.5 GHz to 18.0 GHz and simultaneously exhibits superior load-bearing performance with an out-of-plane Young's modulus of 334.8 MPa and an out-of-plane compressive strength of 4.95 MPa, demonstrating the effectiveness of the co-design scheme. Finally, the experimental results are analysed. This study provides a reference for co-design and multi-objective optimization of similar multifunctional structures.

Structural fiber-reinforced polymer (FRP) composite materials consisting of a polymer matrix reinforced with layers of high-strength fibers are used in numerous applications, including but not limited to spacecraft, vehicles, buildings, and bridges. Researchers in the past few decades have suggested the necessary integration of sensors (e.g., fiber optic sensors) in polymer composites to enable health monitoring of composites’ performance over their service lives. This work introduces an innovative cognizant composite that can self-sense, compute, and implement decisions based on sensed values. It is a critical step towards smart, resilient infrastructure. We describe a method to fabricate textile sensors with flexible circuitry and a microcontroller within the polymer composite, enabling computational operations to take place in the composite without impacting its integrity. A microstructural investigation of the sensors showed that the amount of oxidative agent and soaking time of the fabric play a major role in the adsorption of polypyrrole (PPy) on fiberglass (FG). XPS results showed that the 10 g ferric chloride solution with 6 h of soaking time had the highest degree of protonation (28%) and, therefore, higher adsorption of PPy on FG. A strain range of 30% was achieved by examining different circuitry and sensor designs for their resistance and strain resolution under mechanical loading. A microcontroller was added to the circuit and then embedded within a composite material. This composite system was tested under flexural loading to demonstrate its self-sensing, computing, and actuation capabilities. The resulting cognizant composite demonstrated the ability to read resistance values and measure strain using the embedded microcontroller and autonomously actuate an LED light when the strain exceeds a predefined limit of 2000 µε. The application of the proposed FRP system would provide in situ monitoring of structural composite components with autonomous response capabilities, as well as reduce manufacturing, production, and maintenance costs.
