“…Besides, the wear rate decreased from 12.75 × 10 −6 mm 3 N −1 m −1 to 3.89 × 10 −6 mm 3 N −1 m −1 , a notable reduction of 69.52% compared with pure POM. This value is far less than most wear‐resistant composite materials, such as polyimide enhanced by oxidized carbon (1.163 × 10 −5 mm 3 N −1 m −1 ) 53 and epoxy resin with boron carbide reinforcement (10.09 × 10 −5 mm 3 N −1 m −1 ) 54 . This can be explained by the introduction of ultrafine AFW into the POM.…”

Aramid fiber is widely used in aerospace, machinery, construction, and other fields for its high strength, high elastic modulus, lightweight, and superior comprehensive performance. However, because aramid fiber is difficult to be melted and reprocessed, efficient and environmentally friendly recycling of aramid fiber waste (AFW) is an urgent and challenging issue. In this work, we reported a facile way to recycle AFW for the preparation of friction-resistant polyoxymethylene (POM)/AFW composites. The ultrafine AFW powder with 64.69 μm in size was fabricated by solid state shear milling (S3M) technology, which broke the amide bond due to the strong compression and shearing during milling.With the increase of milling cycles, the roughness and active groups on the surface of AFW were increased, which was contributed to improving the compatibility between AFW and POM matrix. The morphology observation indicated a good dispersion of AFW in POM. The mechanical property test results showed that the flexural strength increased from 52.69 MPa to 80.12 MPa with 20 wt.% AFW. As a friction modifier, the addition of AFW could improve the tribological properties of POM/AFW composites, and the coefficient of friction (COF) and wear rate of composites with 20 wt.% AFW could decrease by 53.02% and 69.52%, respectively. The S3M technology presented in this work is an efficient and industrialized strategy for AFW recycling to prepare value-added products, which has great potential in the engineering application field.

“…The shear effect of the steel ring caused the melting layer to ). 54 This can be explained by the introduction of ultrafine AFW into the POM. After 10 milling cycles, the AFW had become the ultrafine powder, and its surface had been sheared to form large microfibers with rougher surface area, as shown in Figure 1F.…”

The attenuation of electromagnetic (EM) energy with polymeric nanocomposite foams is significant because the microwave energy is diminished by multiscattering of EM into microcellular structure. In this study, acrylonitrile butadiene styrene (ABS) and multi‐walled carbon nanotubes (MWCNTs) nanocomposite foams were fabricated via a chemical foaming in an injection‐molding process. It was demonstrated that the skin depth in foamed ABS/MWCNT specimens was fallen dramatically compared to their solid counterparts. The diminution of skin depth for foamed ABS/1 wt% of MWCNT nanocomposite was 21.7% compared to solid pure ABS. The reflectance of pure ABS was decreased by foaming but it was increased in foamed ABS/MWCNT nanocomposite. The absorption of microwave was improved by foaming and adding MWCNTs in ABS matrix. The utmost value of the experimental absorption shielding effectiveness (SEA. experimental), 14.26 dB, was found for the foamed ABS/1 wt% of MWCNT, holding pressure of 2 s and cooling time of 60 s F8, at 8.7 GHz. It was demonstrated that traveling path of EM wave was prolonged by the introduction of microcellular structure in ABS/MWCNT nanocomposite. Moreover, the contribution of MWCNT, holding pressure time, and cooling time to traveling path were achieved 76.7%, 8.5%, and 7.3%, respectively.Highlights ABS/MWCNTs nanocomposite foams were fabricated by chemical foaming process. Skin depth in foamed nanocomposite samples was fallen compared to solids. Reflectance of pure ABS was decreased by foaming. Absorption of microwave was improved by foaming and MWCNTs. Traveling path of EM wave was prolonged by microcellular structure.

“…23 According to Tasyurek and Duzcukoglu, the wt.% loading of boron carbide was the most important factor affecting the tribological properties of epoxy resin. 71 By varying the volume percent of the carbon nanotube, applied load, sliding speed, and sliding distance, Venkatesan et al reported that increasing the volume percent loading of carbon nanotubes in the epoxy matrix, reduced nanocomposites' wear rate. 72 Increases in applied load and sliding speed, on the other hand, increased the wear rate value of the samples.…”

Wear parameter optimization is critical for the successful use of materials in load-bearing applications. This study examines the optimization of various wear parameters using the Taguchi technique for the determination of the specific wear rate of alpha-manganese dioxide (α-MnO2)-epoxy nanocomposites. Four factors viz. wt.% loading of α-MnO2, sliding distance, sliding velocity, and normal load, were selected as controllable factors and a suitable L16 orthogonal array was chosen for conducting experiments. An X-ray diffractometer and field emission scanning electron microscope were used to examine phase identification, surface morphology, and chemical composition. With the addition of α-MnO2 in the epoxy, the tensile stress is decreased, while the elastic modulus is increased. The Taguchi result shows that the wear test in optimal condition is carried out with a wt.% loading of α-MnO2 of 0.5%, a sliding distance of 500 m, a sliding velocity of 1.5 m/s, and an applied normal load of 5 N. Analysis of variance shows the wt.% loading of α-MnO2 has the most influential parameter on specific wear rate with a contribution of 87.94%. The analysis also shows that the general linear model accurately describes the effect of sliding wear parameters on specific wear rates. The Monte Carlo simulated model shows that the experimental signal-to-noise ratios are consistent with the simulated model values. The confirmation test result shows that the % error between the predicted and experimental values of the specific wear rate at the optimum level combination is 4.67%. The worm surfaces of different trial runs show that the material removal process is caused by crack propagation. High-resolution scanning electron microscopic images of fractured surfaces show the formation of a stable tribo-layer at 0.5 wt.% α-MnO2 loading resulted in a significant decrease in the specific wear rate of the sample.
