“…When the chemical etching process was achieved after peel ply removal, it removed the contaminants of the peel ply, cleaned the composite substrate, and added micro-roughness to the composite substrate surface ( Figure 7 b). The additional process after peel ply treatment etched the surface homogeneously at the microlevel (without disturbing bulk properties) [ 18 ]. This allowed for an improvement in the contact area and interlocking points between the adhesive and composite substrate surfaces.…”

In aerospace and automotive applications, composite materials are used as a major structural material along with metals. Composite-metal and metal-metal joining are very crucial in such structures. Adhesive bonding is commonly used for this purpose. Since such structures are exposed to varying temperatures and dynamic loads, it is essential to investigate the response of such joints under thermomechanical loading. Though various studies have been reported in the literature to assess the thermomechanical properties of composites, adhesives, and their joints, the effect of the surface treatment of metals and composites on the improvement in the thermomechanical behavior of the joints has not been reported. The metal and composite surfaces were modified using chemical etching techniques. The interaction between adhesives and adherends was studied using the DTMA technique in compression mode. Anodizing treatment on aluminum alloys improved the stiffness properties of metallic joints to 36% and decreased the damping to 23%, while chemical treatment on composite and metal adherends increased the stiffness of composite-metal joints to 34% and reduced the energy dissipation to 20%.

“…These PNCs are synthesized when nanosized particles of various shapes and sizes are reinforced into a polymer matrix [ 5 ]. However, the reinforcing impact of these nanoparticles is highly dependent on the aspect ratio, size, orientation and dispersion [ 6 ]. The reinforcement of these nanofillers ultimately enhances PNC’s mechanical, thermal, barrier and flammability properties without compromising their processability [ 7 , 8 ].…”

Carbon-based 0D materials have shown tremendous potential in the development of biomedical applications of the next generation. The astounding results are primarily motivated by their distinctive nanoarchitecture and unique properties. Integrating these properties of 0D carbon nanomaterials into various polymer systems has orchestrated exceptional potential for their use in the development of sustainable and cutting-edge biomedical applications such as biosensors, bioimaging, biomimetic implants and many more. Specifically, carbon dots (CDs) have gained much attention in the development of biomedical devices due to their optoelectronic properties and scope of band manipulation upon surface revamping. The role of CDs in reinforcing various polymeric systems has been reviewed along with discussing unifying concepts of their mechanistic aspects. The study also discussed CDs optical properties via the quantum confinement effect and band gap transition which is further useful in various biomedical application studies. Graphical Abstract

“…Raza et al 40 studied process‐induced deformations in glass/unsaturated polyester cross‐ply C‐shaped cylindrical structures and found that the value of diameter reduction was reduced from 6 to 3 mm by the addition of 5% silica particles. Ahmad et al 41 investigated the effect of different dielectric and magnetic nanoparticles on the electrical, mechanical, and thermal properties of carbon fiber‐reinforced composites. They found that the composite samples containing MWCNT nanofiller showed the highest electrical, thermal, and mechanical properties among the dielectric nanofillers, and the composite samples containing titanium oxide nanofillers showed better flexural, electrical, and thermal properties among magnetic nanofillers.…”

Experimental study on the mechanical properties of three‐dimensional braided composite circular tubes with preembedded licker‐in

This study investigates the tensile and compression properties of three‐dimensional five‐direction (3D5D) braided composite circular tubes with preembedded titanium alloy licker‐ins. The influence of the braided angle, braided thickness, and braided configuration on the bearing capacity is analyzed, and the microdamage morphology and failure mechanism of the tube structure are examined using scanning electron microscopy. Results show that the 3D5D braided tube has a larger tensile failure load than the 3D full five‐direction braided tube of the same outer diameter. In circular tubes of the same braided configuration and outer diameter, the compression failure load increases with the wall thickness, and the C‐ø30t3 circular tube achieves the maximum compression failure load. The damage morphology is characterized by the pulling‐off failure of the licker‐in joint. The T‐ø30t2.5 and T‐ø25t3 circular tubes achieve a large failure load, with an average tensile load of over 120 kN. The failure morphology is characterized by the cracking of the fiber at the end of the tube after the licker‐in joint has been pulled off. The average tensile failure load of the T‐ø30t3 circular tubes is over 105 kN, and the failure morphology reveals a broken licker‐in joint, indicating design deficiencies that require further optimization. The findings of this paper can provide an important scientific basis for the lightweight and high‐strength connection design for 3D braided composites in near‐space aerostats and their flight applications.
