“…When compared to the pristine PA11, the presence of SiO 2 in the PA11 resulted in a higher elasticity modulus and a decrease in the break elongation. The findings are consistent with previous research [ 43 , 44 ].…”

Acidic gas penetration through the internal pressure sheath of a flexible riser tends to cause a corrosive environment in the annulus, reducing the service life of the flexible riser. Nanoparticles can act as gas barriers in the polymer matrix to slow down the gas permeation. Herein, we prepared PA11/SiO2 composites by the melt blending method. The effect of adding different amounts of SiO2 to PA11 on its gas barrier properties was investigated by conducting CO2 permeation tests between 20 °C and 90 °C. As the temperature increased, the lowest value of the permeability coefficient that could be achieved for the PA11 with different contents of SiO2 increased. The composites PA/0.5% SiO2 and PA/1.5% SiO2 had the lowest permeation coefficients in the glassy state (20 °C) and rubbery state (≥50 °C). We believe that this easy-to-produce industrial PA/SiO2 composite can be used to develop high-performance flexible riser barrier layers. It is crucial for understanding riser permeation behavior and enhancing barrier qualities.

“…The nanographite of nanoscale was used in small weight fraction into the epoxy. To make certain, even distribution of nanomaterial stirrer was employed [20][21][22][23][24]. The composite was left to cure two days, postcured at 180 °C for 4 hours in a void oven.…”

The nanoparticles are incorporated into the composite to mark their unique properties. This work investigates the hybrid epoxy nanocomposite and the impact of nanographite reinforcement. The composite was prepared by using a mechanical stirring technique. The amount of nanographite was added in different volumes, i.e., 1.0, 1.5, and 2.0 wt.%. Results of mechanical and dynamic loading properties were analyzed in accordance to the quantity of nano-G. The fiber and matrix interfacial bonding enrichments were evident in high-resolution SEM images-tensile fracture surface. Finally, the optimum content of nanoparticle which impacts the sample greatly was found to be 1.5 wt.%.

“…Cerium zirconium oxide nanoparticles exhibit good electrical and thermodynamic properties with a high degree of reactivity. 65 The mechanical properties of the composite created are examined in this research, including tensile strength, impact strength, and flexural strength. When 1 wt.% of nanoparticles are loaded, mechanical properties are at maximum value, however after that the values decrease.…”

Glass fiber reinforced composite has gained attention from various engineering fields because of its enhanced properties. This paper reviewed the mechanical characteristics, such as tensile strength, flexural strength, hardness number, impact strength, wear percentage, etc., of the composites from different experimental studies performed by various researchers over time; by varying with the weight percentage of different metal and non-metal nanoparticles. The main observation was that the mechanical properties remained optimal at a certain quantity of nanoparticles was added beyond which these characteristics began to decrease. When more than one type of nanoparticle is dispersed, or micro rubber particles are added with a specific type of nanoparticle, the properties are more pronounced than when only a single type of particle is used.
