These outstanding properties lead to its diverse applications in automobiles, aerospace, robots, sports equipment. PEC is machined by the conventional machining techniques like cutting, drilling, power hacksaw etc. Some of the limitations observed in conventional machining of these such as tool jamming, damage to surface topology, and fibres. To overcome the aforesaid limitations, in this work attempts to introduce rotary ultrasonic drilling (RUD) as viable option for machining of PEC. This work carries out the investigational study of input control factors on material removal rate (MRR) and surface roughness (SR). The outcomes of the study reveal that the with right selection of drilling control factors, better quality holes with superior topography as compared to conventional drilling, good surface finish, small exit chip sizes, low overcut errors are obtained. Interacting levels of higher spindle speed and a lower feed rate generated better surface characteristics.

Characterization using X-ray diffraction (XRD) techniques, scanning electron microscopy (SEM), impedance spectroscopy (IS), Raman spectroscopy (RS), thermogravimetric analysis (TG) and differential scanning calorimetry (DSC) revealed distinct features. XRD analysis of nanocomposites showed both weak and high-intensity peaks at different scattering angles (2θ = 8°–11° and 20°–22°), indicating amorphous phases PS phases with varying sizes of nanoparticles. It has been proved that the addition of higher amounts of ZnO leads to the disappearance of the maximum of weak intensity in the studied substance (PS/10%ZnO), which is due to the formation of microcrystalline regions that lead to the formation of sharp maxima with high intensity. It was determined that the increase in the concentration of ZnO up tp 5 % volume content enhances the dielectric permeability (ε) and polarization capacity of polystyrene. It is believed that, depending on the ZnO concentration, the increased dielectric permeability and polarizability are attributed to phases with different charge densities at the boundaries between the ZnO nanoparticles and the matrix, which promotes additional polarization and contributes to the overall enhanced permittivity. This formation of interfacial boundaries is evident from the stepwise shape of the thermogravimetric (TG) curve with increasing ZnO content. The introduction of ZnO nanoparticles into PS results in the formation of new phases, altering the intensity and position of peaks observed at frequencies of 376 cm⁻1 and 485 cm⁻1 in the Raman scattering spectrum, partially shifting towards higher frequencies.","PeriodicalId":17446,"journal":{"name":"Journal of Thermoplastic Composite Materials","volume":"30 1","pages":""},"PeriodicalIF":3.3,"publicationDate":"2024-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142189694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By incorporating a 1 wt% concentration of MWCNT, applying a pressure time of 2 s, and allowing for a cooling time of 60 s, foamed nanocomposite samples demonstrated a remarkable total EMI shielding effectiveness (SE) of SET = 16.25 dB. This SE value surpassed the EMI SE values of the remaining samples across the X-band frequency range. Upon comparing foamed samples of pure and nanocomposite materials with identical cell density, it was observed that the enhancement of SET for the nanocomposite foamed sample reached 21.2% in contrast to the pure foamed sample operating at 11.52 GHz.

Samples were fully immersed in the mixture of GW (20:80) at 50°C, 70°C and 90°C for up to 80 days and periodically weighted. Results gathered revealed the occurrence of substantial changes especially for PA6 samples aged at 90°C. The long term ageing leads to the formation of ester species due to thermo-oxidation as pointed out by Infrared spectroscopy analysis. Moreover, dynamic mechanical analysis measurements showed that glycol water acted as an effective plasticizer in lowering the Tg of the polyamide 6. This plasticizer effect was confirmed by the gain of ductility at early stage of ageing for both materials (PA6 and PA6GF30). Nevertheless, after 80 days of ageing the effect of glycol water ageing is no longer physical in nature and an overall loss of mechanical properties was noticed. Indeed, an embrittlement of PA6 was measured that can be attributed to a decrease of the level of entanglements within the polymer. Nevertheless, for PA6GF30 material, the loss of strength and stiffness was the result of the interfacial debonding between the fibers and the matrix.","PeriodicalId":17446,"journal":{"name":"Journal of Thermoplastic Composite Materials","volume":"41 1","pages":""},"PeriodicalIF":3.3,"publicationDate":"2024-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142189649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It systematically analyzes the heating mechanism, temperature field distribution, and surface temperature hysteresis of CF-PP with different fiber weave structures during the heating process. Based on the observed temperature distribution and variation patterns during material heating, an improved particle swarm Fuzzy PID control method is proposed, which effectively reduces temperature overshoot and enhances the system’s resistance to disturbances.

Photosensitive materials and shrinkage-induced internal tensions seems to be its major constraint. Additionally, SLS 3D printing has improved composite materials' electrical, mechanical, and thermal properties. It has drawbacks including permeable structures and internal tensions. In FDM 3D printing, mechanical and electrical qualities are improved for piezoelectric sensor manufacture. Warping and nozzle blockage require additional study. DIW’s versatility in constructing complicated structures with increased features for energy harvesting and sensor development is also mentioned. We identify ink development and printer nozzle clogging issues. The review concludes that inkjet printing can provide a variety of materials for flexible electronics.

The findings confirmed the successful synthesis of sphere-like CdS with a cubic structural phase. The stress-strain curves of PVB and its composites with nano CdS spheres were examined. The PVB has a direct/indirect energy gap of 5.1 eV (4.1 eV). With a CdS doping level of 2% and 4%, the values correspondingly decreased to 4.76 eV (3.36 eV) and 4.49 eV (2.45 eV).
