“…It is beneficial to the stress transfer between fillers and matrix under the action of external force, leading to the improvement of the tensile strength of composites(Figure 5B). 46,47 Besides, the ultrafine AFW powder played the role of heterogeneous nucleation in the matrix and improved the crystallinity of POM(Table 1), 48 thus improving the mechanical properties of the composites. For impact property, the notch impact strength of POM/AFW composites was lower than pure POM (8.22 kJ/m 2 ).…”

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 effects of multiwall carbon nanotubes (MWCNTs) on the electrical, dielectric, and piezoelectric properties of the ferroelectric ceramic/castor-oil polyurethane (PUR) composite films were evaluated. The three-phase piezoelectric composites were produced by keeping PUR concentration constant while varying lead zirconate titanate (PZT) volume fractions between 10 and 50 vol.%, at two MWCNT concentrations: above and below percolation threshold. The dc electrical conductivity analysis revealed that small amounts of MWCNTs dispersed within PUR/PZT composite films can significantly improve electrical and piezoelectric properties due to their ability to act as conductive bridges between PZT particles in the samples. Using Jonscher's power law, it was possible to determine that the electrical conduction in ac regime occurs through spatial charge hopping between states located within the piezoelectric composite. Analyzing the piezoelectric properties through the d 33 coefficient, it was found that PUR-MWCNT/PZT piezoelectric composite displayed higher d 33 values (20 pC/N) in comparison to the PUR/PZT two-phase composite (9.5 pC/N) for all PZT loadings. According to these results, the dispersion of MWCNT nanoparticles influences the poling effectiveness of the PZT particles and increases the d 33 coefficient of three-phase piezoelectric composites.
