In the present work, amine‐functionalized palm flower carbon (f‐PFC)‐reinforced 9, 10‐dihydro‐9‐oxa‐10‐phosphaphenanthrene‐urea diamine‐based cardanol benzoxazine‐epoxy hybrid (DUDCBz‐EP) composites have been developed and characterized. Differential scanning calorimeter analysis indicate that the amine‐functionalized palm flower carbon‐reinforced cardanol‐benzoxazine/epoxy (f‐PFC/DUDCBz‐EP) hybrid composites possess the higher values of glass‐transition temperature (Tg) than that of hybrid matrix (DUDCBz‐EP). Results from TGA infer that the PFC reinforcement significantly improves thermal stability and char yield according to the percentage weight. Morphological studies ascertain the amorphous structure and uniform as well as homogeneous dispersion of PFC reinforcement in the hybrid matrix. Contact angle measurements indicate that both the hybrid matrix and composites developed in the present work possess hydrophobic behavior. Data obtained from corrosion studies infer that the hybrid matrix as well as hybrid composites exhibit significant corrosion‐resistant behavior toward the surface of the steel specimen due to inherent characteristics of both benzoxazine and epoxy matrix, in addition to amine‐functionalized PFC. The results obtained from different studies, it is suggested that these hybrid matrix possess significantly improved properties and can be exploited for high‐performance cost competitive coatings for different industrial applications including protection of steel surfaces from corrosion.

“…Polyhedral oligomeric silsesquioxanes (POSS) reagents have appeared as alternative materials, which can be incorporated easily in a polymer matrix like acrylics, styryls, epoxy and polyethylene. A high-performance 10-dihydro-9-xa-10-phosphaphenanthrene-10-oxide (DOPO)-based phosphorus tetraglycidyl epoxy nanocomposite has been proposed by Meenakshi et al (Meenakshi et al 2011) for aerospace structural applications due to its good mechanical, thermal, flame-retardant and water absorption properties. The nanoreinforcement POSS amine was mixed with the epoxy resin followed by curing process.…”

This paper reviews the potential of polymer and ceramic matrix composites for aerospace/space vehicle applications. Special, unique and multifunctional properties arising due to the dispersion of nanoparticles in ceramic and metal matrix are briefly discussed followed by a classification of resulting aerospace applications. The paper presents polymer matrix composites comprising majority of aerospace applications in structures, coating, tribology, structural health monitoring, electromagnetic shielding and shape memory applications. The capabilities of the ceramic matrix nanocomposites to providing the electromagnetic shielding for aircrafts and better tribological properties to suit space environments are discussed. Structural health monitoring capability of ceramic matrix nanocomposite is also discussed. The properties of resulting nanocomposite material with its disadvantages like cost and processing difficulties are discussed. The paper concludes after the discussion of the possible future perspectives and challenges in implementation and further development of polymer and ceramic nanocomposite materials.

In this study, the flame retardants epoxy nanocomposites were prepared by combining mechanical stir and sonication of epoxy Epikote 240 (EE240) resin, chlorinated paraffin, atimony oxide, multi-walled carbon nanotubes (MWCNTs) and montmotillonite clay. Resultants of CNTs, montmorillonite and flame retardant additives were investigated limiting oxygen (LOI) and UL-94, combustion rate. The SEM, FE-SEM, TEM were measured to analyze the dispersion of MWCNTs and montmorillonite clay in epoxy matrix. The mechanical properties including tensile strength, compressive strength, flexural strength and impact strength Izod were studied. The results of testing burning and mechanical properties indicated that CNTs were more efficient than clay in improving the flame retardancy of materials. The dispersion method combining of mechanical stir and sonication is the good choice to distribute additive agents into epoxy matrix.
