“…Furthermore, epoxy equivalent weight (EEW), amine hydrogen equivalent weight (AHEW) and amount of the desired load were determined by using Eqs. (1), (2), and (3), respectively. In addition, the ratio by weight of the crosslinking relative to the decafunctional matrix was evaluated per 100 parts per hundered of epoxy resin (PHR) (Eq.…”

Epoxy polymer, namely, decaglycidyl pentamethylene dianiline of phosphorus (DGPMDAP) was synthesized in three steps. The synthesis of epoxy polymer DGPMDAP was investigated by nuclear magnetic resonance spectroscopy, rheological analysis, scanning electron microscope (SEM), stationary and transient electrochemical methods (PDP and EIS), respectively. The rheological properties of composite (DGPMDAP/MDA/TiO2) without and with different percentages of titanium dioxide (0%, 5%, 10% and 15%) increase with both the increase in frequency and with rate of load of titanium dioxide. Besides, SEM micrographs shows a good dispersion of the titanium dioxide charge in the composite (DGPMDAP/MDA/TiO2) elaborated. The results of PDP show that epoxy polymer DGPMDAP acts as mixed type inhibitor and reaches maximum corrosion inhibition efficiency reaches 92 % at 10−3 M. Besides, EIS results indicate that DGPMDAP act as good inhibitor for carbon steel in 1 M HCl solution and its efficiency reaches 91 % at 10−3 M of DGPMDAP. Furthermore, the adsorption of DGPMDAP on carbon steel surface obeyed Langmuir isotherm.

“…A few publications could be found on the adhesion of nanofilled systems to the reinforcing fibers and on the final properties of the nanofilled reinforced plastics , but the number of such papers is growing . Two groups of factors should be taken into account when considering the probable effect of the nanofillers on the matrix adhesion to the reinforcing fiber: those influencing formation and debonding of adhesion joints.…”

Epoxy nanocomposites as matrices for aramid fiber‐reinforced plastics

Rheological and mechanical properties of nanofilled epoxy resin were studied, including adhesion to aramid fibers and strength of impregnated aramid strands. Light scattering and rheological measurements data imply that nanodiamonds (NDs) and multiwall carbon nanotubes form stable nanosized agglomerates in epoxy resin, whereas for epoxy‐organomodified montmorillonite systems, individual clay platelets orientation might be present. Also, according to the rheology of these systems, formation of the networks of epoxy molecules adsorbed on the NDs particle surface is suggested. Increase in the viscosity of the epoxy oligomers due to the nanoparticles incorporation results in the worsening of the impregnation of the aramid fibers by these formulations. However, enhanced adhesion properties could be obtained when using nanofillers, with a maximum at 1–2 wt% of nanofillers. A 25–35% growth of the pull‐out adhesion strength is also achieved. Increased cohesive strength and decreased residual stresses are supposed to be the reasons of adhesion strength decrease according to the literature. Adhesion strength increase was accompanied by a 10% enhancement of the strength of impregnated aramid strands. Moreover, a notable effect—up to a fourfold increase—was observed for the impact toughness of epoxy‐nanofillers samples. POLYM. COMPOS., 39:E2167–E2174, 2018. © 2017 Society of Plastics Engineers

Polyester based polymers are extensively used in aggressive marine environments; however, inadequate data is available on the effects of the seawater on the polyester based nanocomposites mechanical properties. This paper reports the effect of seawater absorption on the mechanical properties degradation of halloysite nanoclay-polyester nanocomposites. Results confirmed that the addition of halloysite nanoclay into polyester matrix was found to increase seawater uptake and reduce mechanical properties compared to monolithic polyester. The maximum decreases in microhardness, tensile and flexural properties, and impact toughness were observed in case of 1 wt% nanoclay. The microhardness decreased from 107 HV to 41.7 HV (61% decrease). Young’s modulus decreased from 0.6 GPa to 0.4 GPa (33% decrease). The flexural modulus decreased from 0.6 GPa to 0.34 GPa (43% decrease). The impact toughness dropped from 0.71 kJ/m2to 0.48 kJ/m2(32% decrease). Interestingly, the fracture toughnessKICincreased with the addition of halloysite nanoclay due to the plasticization effect of the resin matrix. SEM images revealed the significant reduction in mechanical properties in case of 1 wt% reinforcement which is attributed to the degradation of the nanoclay-matrix interface influenced by seawater absorption and agglomeration of halloysite nanoclay.
