“…The shiny region marked the blue lines depict the reflection of the light source because of the presence of Diamond-Like Carbon (DLC) entities, such as MWCNTs nanoparticles. The breakage of the polymer chains at a higher level of reinforcement can be seen in Figure 10 , which also indicates the poor distribution of MWCNTs and the lack of interfacial adhesion between the polymer chains [ 29 , 30 , 31 , 32 ]. The reinforcement at 0.3 wt.% of the epoxy/MWCNTs, as shown in Figure 9 , indicates good dispersion and good interfacial linkage in-between the fillers-matrix.…”

Epoxy resins, due to their high stiffness, ease of processing, good heat, and chemical resistance obtained from cross-linked structures, have found applications in electronics, adhesives coatings, industrial tooling, and aeronautic and automotive industries. These resins are inherently brittle, which has limited their further application. The emphasis of this study is to improve the properties of the epoxy resin with a low-concentration (up to 0.4% by weight) addition of Multi-Walled Carbon Nanotubes (MWCNTs). Mechanical characterization of the modified composites was conducted to study the effect of MWCNTs infusion in the epoxy resin. Nanocomposites samples showed significantly higher tensile strength and fracture toughness compared to pure epoxy samples. The morphological studies of the modified composites were studied using Scanning Electron Microscopy (SEM).

“…This trend showed the multistage decomposition of the composite with and without wire mesh. The onset temperatures for composites without and with steel mesh were 333 °C and 332 °C, respectively for 0.5 v f of the natural fiber, whereas for 0.52 v f onset temperatures for composites without and with steel mesh were 338 °C and 332 °C, respectively [42][43][44]. The first peak of weight derivative occurred at 358 °C and 324 °C for composites without and with steel mesh, respectively for 0.4 v f of the fiber, whereas for 0.5 v , f it occurred at 351 °C and 358 °C for composites without and with steel mesh, respectively.…”

The utilization of natural fiber composites has been increased in replacing various parts in the automobile sector made up of synthetic fiber due to its degradability nature and environment friendliness. In this work, the naturally available Asna fiber was processed and the composites were prepared without and with steel wire mesh in various volume fractions (vf) of the fiber. In the present experimental investigation, the influence of different composite on the thermal, mechanical, and water absorption characteristics. Various properties such as tensile, flexural and impact strength were tested for the multiple composites. Subsequently, a simulation model of a car front bumper was prepared using ANSYS to test it while defining the determined properties of the composites. The test results showed that when vf was increased from 0.4 to 0.5%, the tensile and flexural were decreased by 0.72% and 59%, respectively, whereas impact strength was increased by 5.9% for the composite without wire mesh. The tensile and flexural strengths were decreased by 18.2 %, whereas impact strength was increased by 1.6% for 0.5 vf of the composite when steel wire mesh was added to the composite. The investigation of composite’s thermal behavior showed that when the temperature range comes within 330-370oC, the composites started decomposing. Various images were captured using Scanning Electron Microscope to investigate the fibers’ dispersion in epoxy polymers and its interfacial bonding. The simulation results showed that the bumper made up of the composite with wire mesh provides a better impact strength as compared to other composites and steel.

The utilization of various energy sources to assist the machining process has become prominent to achieve substantial improvement in machining performance. These energy sources have also resulted in an alternative to cutting fluids which is safer for both the universe and human beings. The combined action of laser and ultrasonic vibration energies during the turning process has shown significant achievement in machining process capabilities. Therefore, an attempt has been made to provide ultrasonic vibration in the radial direction and laser to preheat aluminium 3003 alloy simultaneously during the ultrasonic-vibration-laser assisted turning (UVLAT) process. Machining performance has been analyzed in terms of machining forces, machining temperature, chip morphology, surface damage, and surface roughness. A comparative machining performance analysis has been carried out among the conventional turning (CT), laser assisted turning (LAT), ultrasonic vibration assisted turning (UVAT), and UVLAT processes. The outcomes of the current study indicate significant benefits of the UVLAT process on the machining performance of aluminium 3003 alloy. However, surface damage and surface roughness have been affected negatively during the UVLAT process due to the pin-point hammering and particle adhesion on the workpiece part. Hence, the selection of vibration direction is a critical factor during the vibration machining processes.
