Nanotechnology has become one of the best ever growing technology in scientific and engineering disciplines. Various investigations on nanoparticles have been carried out by many research scholars in the earlier decades. This research work investigates the effect of hybrid e-glass reinforced fiber with epoxy nanocomposite. The nanocomposite laminates were prepared by hand layup technique by varying percentages of Titanium Dioxide (TiO2) nanoparticles of 0, 1, 2 and 3% respectively. The nano additives are added to improve the strength, from wear out resistance and hardness of the polymer composite. The nanocomposite laminates thus prepared are characterized by X-ray diffraction (XRD) and Scanning Electron Microscope (SEM) tests. The XRD test revealed that the nanoparticles are well typified and a fully intercalated structure was obtained. By using SEM the fracture failures and matrix cracks on the surfaces of the laminates were investigated. The flexural properties of the glass fiber reinforced plastics improved with the addition of nano TiO2 filler particles. At 3 wt % of TiO2 the flexural strength of 203.36 Mpa was attained. Good interfacial bonding between the fiber and epoxy was the main reason for achieving better flexural properties.

Microcrystalline diamond (MCD) and fine-grained diamond (FGD) films are deposited on silicon nitride (Si3N4) inserts using the hot filament chemical vapor deposition (HFCVD) method. Scanning electron microscope (SEM), X –ray diffraction (XRD) and Raman spectrum are employed to characterize these as-deposited diamond films. Cutting performance of as-fabricated CVD diamond coated Si3N4 inserts is examined in dry turning glass fiber reinforced plastics (GFRP) material, comparing with the uncoated Si3N4 inserts. The results indicate that the tool failure is mainly attributed to its severe flank wear, which is caused by continuous friction and impact brought by many hard SiO2 particles distributed in the GFPR work piece. The lifetime of Si3N4 inserts can be prolonged by depositing MCD or FGD films on them and the FGD coated insert shows better wear resistance than the MCD coated one.

To reuse waste glass fiber-reinforced plastics (GFRPs), porous ceramics (i.e., GFRP/clay ceramics) were produced by mixing crushed GFRP with clay followed by firing the resulting mixture under different conditions. The possibility of using ceramics fired under a reducing atmosphere as adsorbent materials to remove NOx and SOx from combustion gases of fossil fuels was investigated because of the high porosity, specific surface area, and contents of glass fibers and plastic carbides of the ceramics. NO2 and SO2 adsorption tests were conducted on several types of GFRP/clay ceramic samples, and the gas concentration reduction rates were compared to those of a clay ceramic and a volcanic pumice with high NO2 adsorption. In addition, to clarify the primary factor affecting gas adsorption, adsorption tests were conducted on the glass fibers in the GFRP and GFRP carbides. The reductively fired GFRP/clay ceramics exhibited high adsorption performance for both NO2 and SO2. The primary factor affecting the NO2 adsorption of the ceramics was the plastic carbide content in the clay structure, while that affecting the SO2 adsorption of the ceramics was the glass fiber content.
