“…The properties of polymer materials are directly related to the final molding quality of small module plastic gears. The selection of plastic gear materials should comprehensively consider three aspects: service performance, process performance and economic cost [ 44 ]. Polyformaldenyde (POM) [ 45 , 46 ], as the most used thermoplastic engineering plastic for gear products, has excellent comprehensive properties.…”

This paper was aimed at finding out the solution to the problem of insufficient dimensional accuracy caused by non-linear shrinkage deformation during injection molding of small module plastic gears. A practical numerical approach was proposed to characterize the non-linear shrinkage and optimize the dimensional deviation of the small module plastic gears. Specifically, Moldflow analysis was applied to visually simulate the shrinkage process of small module plastic gears during injection molding. A 3D shrinkage gear model was obtained and exported to compare with the designed gear model. After analyzing the non-linear shrinkage characteristics, the dimensional deviation of the addendum circle diameter and root circle diameter was investigated by orthogonal experiments. In the end, a high-speed cooling concept for the mold plate and the gear cavity was proposed to optimize the dimensional deviation. It was confirmed that the cooling rate is the most influential factor on the non-linear shrinkage of the injection-molded small module plastic gears. The dimensional deviation of the addendum circle diameter and the root circle diameter can be reduced by 22.79% and 22.99% with the proposed high-speed cooling concept, respectively.

“…According to Mahesh et al [ 22 ], selecting composite constituents appropriately for a specific application is a demanding job for an engineer or designer. In their study, the authors explored various matrix and fiber combinations used in impact applications and documented that existing research focuses primarily on the impact behavior of CFRP around the traditional conventional stiff composites, with sacrificial structures receiving little attention when exposed to the impact.…”

In response to the high demand for light automotive, manufacturers are showing a vital interest in replacing heavy metallic components with composite materials that exhibit unparalleled strength-to-weight ratios and excellent properties. Unidirectional carbon/epoxy prepreg was suitable for automotive applications such as the front part of the vehicle (hood) due to its excellent crash performance. In this study, UD carbon/epoxy prepreg with 70% and 30% volume fraction of reinforcement and resin, respectively, was used to fabricate the composite laminates. The responses of different three stacking sequences of automotive composite laminates to low-velocity impact damage and flexural and crash performance properties were investigated. Three-point bending and drop-weight impact tests were carried out to determine the flexural modulus, strength, and impact damage behavior of selected materials. Optical microscopy analysis was used to identify the failure modes in the composites. Scanning electron microscopy (SEM) and C-scan non-destructive methods were utilized to explore the fractures in the composites after impact tests. Moreover, the performance index and absorbed energy of the tested structures were studied. The results showed that the flexural strength and modulus of automotive composite laminates strongly depended on the stacking sequence. The highest crash resistance was noticed in the laminate with a stacking sequence of [[0, 90, 45, −45]2, 0, 90]S. Therefore, the fabrication of a composite laminate structure enhanced by selected stacking sequences is an excellent way to improve the crash performance properties of automotive composite structures.

“…[13][14][15] However, PP is somewhat crystalline and susceptible to brittle, which reduces the durability, flexibility, and stability of such polymers. 7,9,13 So, to reduce the rigidity and thermo-oxidation degradation of PP, one helpful approach is blending with poly ethylene-co-vinyl acetate (EVA). 16,17 EVA can exploit the mechanical energy more effectively, because of lower glass transition temperature (Tg) than that of PP and is amorphous.…”

“…6,14,25 But the process adds high expense and still needs some improvement in terms of low filler content. 9,19,26 Thus, one great challenge is to minimize filler concentration with optimum mechanical and thermal properties. Moreover, the advantage of interfacial zone in immiscible polymer blend is little explored for hybrid filler nanocomposite.…”

This is critical to maintain better thermal properties, especially thermal conductivity as well as low particle content along with organized particle dispersion in polymer nanocomposites. Thus, this study is designed to develop a nanocomposite containing a constant reinforcing load of binary particles (carbon and alumina) in the binary matrix of polypropylene (PP)/poly ethylene‐co‐vinyl acetate (EVA). The samples were prepared through the melt blending and hot pressing technique. Compared to pure PP/EVA matrix, the nanocomposites showed a shift in Fourier‐transform infrared spectroscopy peak and absorption intensity, which proves better interaction of nanoparticles with the matrix. The Scanning Electron Microscopy analysis showed the nanocomposite having carbon (C) and alumina (A) relative ratio 2:3 offered even structure with better distribution of nanoparticles compared to other nanocomposites. Also, Differential scanning calorimetry and Thermogravimetric analysis revealed that alumina‐rich binary nanoparticles reinforced composites offer an efficient improvement in thermal behavior. Moreover, the nanocomposite containing high alumina relative ratio (C: A = 2:3) gives a sharp shift in thermal conductivity of 1.57 W/m‐k from 1.2 W/m‐k of carbon‐rich nanocomposite (C: A = 3:2) and 0.16 W/m‐k of pure PP/EVA. However, these relative properties emphasize the important role of this nanocomposite as a programmable thermal material.
