Polymers have swiftly replaced conventional metallic materials in aviation due to their lightweight and easy processability. Usages of polymers are presently mostly limited to non‐critical components. Flight safety is paramount in aviation and overrides all other factors. The aviation industry is averse to the usage of polymeric materials in critical component applications owing to the nature of failure being catastrophic. The review has covered various polymeric component failures and their root cause reasons. To overcome the inherent weakness in polymers currently used, a strategy to mimic nature is being explored by researchers. Self‐healing polymers can overtake metals if coupled with safe fail technology. Such materials have additional advantages in terms of enhanced longevity and ultimate life cycle. This review critically analyzed various factors driving research and development of self‐healing material for aviation applications. Various extrinsic and intrinsic self‐healing materials have been reviewed in the present work. Composites with an extrinsic self‐healing mechanism possess good healability and strength and can potentially replace current materials. Further, candidate polymeric materials with intrinsic self‐healing capability for the aviation field are extensively reviewed. Various aviation‐grade polymers like epoxy, Poly(methyl methacrylate), polycarbonate, and elastomeric materials with possible chemistries of intrinsic healing like Diel‐Alder reaction, Shape memory assisted self‐healing and covalently adaptable networks have been critically examined. Authors believe that extrinsic self‐healing technology is mature enough for use in the secondary structure of aircraft. At the same time, present technologies of intrinsic materials are not mature enough for flight safety reasons in aircraft; however, they are candidate materials for UAVs. Fast‐growing aviation field, coupled with the entry of UAVs, calls for environmentally sustainable material support. Therefore, this review explores materials within the sphere of high mechanical properties coupled with a low environmental impact.

High‐frequency dielectric materials have been widely and rapidly applied in areas such as automotive radar, Internet of Things, artificial intelligence, and quantum computing. Currently, the challenge in high‐frequency dielectric materials lies in reducing the dielectric constant (Dk) and dielectric loss (Df) without sacrificing its mechanical properties. This study addresses this challenge by introducing air, as the most common “low dielectric factor,” into the polymer matrix in the form of hollow glass microspheres. Meanwhile, the reactive vinyl groups were also introduced onto the surface of the hollow glass microspheres, enabling an interfacial chemical reaction between the side vinyl groups of polybutadiene and its surface so that the organic–inorganic interface compatibility and interface peel strength are simultaneously improved. Consequently, the minimum Dk of 1.29 and Df of 0.0012 in 3–18 GHz are achieved, and the interface peel strength also reaches 0.65 N/mm. Molecular dynamics simulations, analysis of dielectric properties, and interface peel strength reveal the influence of hollow glass microspheres' morphology and chemical structure on their high‐frequency dielectric performance and adhesive strength. This paper provides effective strategies for the structural design and preparation of high‐frequency, low‐dielectric composites, contributing to the further development of next‐generation microwave communication devices towards higher frequencies and faster information transmission.

Poly(p‐phenylene terephthamide) (PPTA) is an aromatic para‐polyamide with a rigid rod‐like main chain and superior intrinsic mechanical properties but is insoluble in all organic solvents. It has been demonstrated that introducing amino groups to the phenyl rings on the PPTA main chain yields organic‐soluble aminated para‐polyamide known as poly(p‐aminophenylene aminoterephthalamide) ((NH2)2‐PPTA). In this study, an organic‐soluble bismaleimide (BMI)‐grafted (NH2)2‐PPTA (BMI‐g‐(NH2)2‐PPTA) was synthesized by reacting the amino groups of (NH2)2‐PPTA with the double bonds of BMI via Michael addition reaction. BMI‐g‐(NH2)2‐PPTA was then employed as a new macromolecular reinforcing agent that significantly enhances the mechanical properties of BMI/2,2′‐diallyl bisphenol A (BD) resin. With the addition of merely 0.5 wt% of BMI‐g‐(NH2)2‐PPTA, the strength and toughness of both BD resin and BD/carbon fiber (CF) composite laminates are significantly improved without decreasing the heat resistance of the matrix. The uniform dispersion of BMI‐g‐(NH2)2‐PPTA in BD resin and its strong interaction with the matrix result in a more significant enhancement in the mechanical properties compared to directly incorporating (NH2)2‐PPTA into the matrix, providing a new and efficient method for enhancing the mechanical properties of BD resin and its CF composites.Highlights A novel BMI‐grafted aminated para‐polyamide, BMI‐g‐(NH2)2‐PPTA, is synthesized. BMI‐g‐(NH2)2‐PPTA is organic‐soluble and can disperse uniformly in BD resin. BMI‐g‐(NH2)2‐PPTA at 0.5 wt% enhances the strength of BD resin by 50.8%. BMI‐g‐(NH2)2‐PPTA is more efficient than (NH2)2‐PPTA in strengthening BD resin. Mechanical properties of BD/CF laminates are also enhanced by BMI‐g‐(NH2)2‐PPTA.
