“…The TG test is a thermal analysis technique used to measure the relationship between weight and temperature variations under programmed temperature control; the latter is utilized in this process to study the thermal stability of materials [ 16 , 17 ]. Under the thermal decomposition temperature, the resin can maintain its service life for a long period of time [ 18 ].…”

Oil-well cement-based materials have inherent brittleness; therefore, they cannot be directly used to seal oil and gas wells for a long time. To improve the elasticity of oil-well cement-based composites, a flexible epoxy resin system was developed. The flexibility, TG, and SEM of the cured resin system were evaluated. At the same time, the resin was added to oil-well cement-based materials to improve its elasticity. The compressive strength and elastic modulus of resin cement stone were tested, and the microstructure was analyzed by XRD, TG, and SEM/EDS. The results showed that the structure of the cured resin is compact, the thermal decomposition temperature is 243.9 °C, and it can recover its original shape after compression. At the curing age of 28 days, the compressive strength of cement-based composites containing 30% resin decreased by 26.7%, while the elastic modulus significantly decreased by 63.2%, and the elasticity of cement-based composites was significantly improved. The formation of hydration products (e.g., calcium silicate hydrate, and calcium hydroxide) in the resin cement slurry is obviously lower than that of pure cement, which is the reason for the decrease in compressive strength. The flexible structure of polymer particles and polymer film formed by epoxy resin is distributed inside the cement stone, which significantly improves the elasticity of oil-well cement-based composites. The results of this paper are helpful for the design of elastic cement slurry systems.

The application of epoxy resins in high temperature and thermal protection fields is limited due to their low decomposition temperature and low carbon residual rate. In this paper, epoxy resin (EP)/quartz fiber (QF) ceramifiable composites were prepared using a prepreg-molding process. The thermal stability, phase change and mechanical properties after high-temperature static ablation and ceramization mechanism of EP/QF ceramifiable composites were investigated. The addition of glass frits and kaolinite ceramic filler dramatically increases the thermal stability of the composites, according to thermogravimetric (TG) studies. The composite has a maximum residual weight of 61.08%. The X-ray diffraction (XRD) results show that the mullite ceramic phase is generated, and a strong quartz diffraction peak appears at 1000 °C. The scanning electron microscope (SEM) and element distribution analyses reveal that the ceramic phase generated inside the material, when the temperature reaches 1000 °C, effectively fills the voids in composites. The composites have a bending strength of 175.37 MPa at room temperature and retain a maximum bending strength of 12.89 MPa after 1000 °C treatment.

Friction and wear behaviors severely inhibit the regular operation and lifetime of mechanical components served in the ocean extreme environment. Herein, we report a novel in-situ synthesis strategy for fabricating silicon dioxide nanoparticles-reinforced epoxy (EP)-based composite coatings. The crystalline phases, sizes, morphologies, and reaction mechanism of the in-situ-synthesized nanoparticles were characterized, and the mechanical and tribological properties of the EP-silicon dioxide based composite coatings were also investigated in detail. The results showed that the in-situ-synthesized nanoparticles with a size about 100-150 nm were in an amorphous state and were covalently grafted onto the epoxy resin matrix. The thermal stability, nano-hardness and scratch-resistance of the composite coatings have been significantly improved. Moreover, the appropriate nanoparticles greatly reduced the wear rates of the epoxy composite coatings, which decreased by two orders of magnitude than that of pure EP coating when their incorporation content reaches 20 wt%.Additionally, the wear rate of the 15 wt% composite coating under the seawater medium decreased by 79.5 compared to that of pure coating.
