Summary: This study compared the grinding performance of carbon fiber-reinforced epoxy resin (CF/epoxy) and carbon fiber-reinforced poly-ether-ether-ketone (CF/PEEK) composites. Different process parameters were set, and the surface morphologies and roughness of the workpieces were observed and measured. The results showed that the grinding forces were correlated with the grinding depth, feed speed, and wheel speed, and the chip formation mechanism of CF/epoxy and CF/PEEK were investigated. Compared to CF/epoxy, CF/PEEK was more difficult to process but had better surface quality.

Summary: Graphene reinforced copper composites have potential applications in various industries, but the current preparation methods are complicated and expensive. This study successfully prepared graphene reinforced copper composites with excellent overall properties by combining electrodeposition, thermal reduction, and sintering. The addition of graphene improved the nucleation process and refined the grains, resulting in improved mechanical properties. The copper matrix was purified, and the oxygen-containing functional groups of graphene oxide were partially repaired, leading to improved electrical properties. Compared to the one-step electrodeposition method, the graphene in the composites had fewer oxygen-containing functional groups, ensuring thermal stability.

Summary: To improve the properties of CF/PEEK composites, carboxylated PEEK (PEEK-COOH) with different carboxylation degrees was synthesized as a sizing agent. The activated CF surface was then coated with PEEK-COOH sizing layers to prepare the CF/PEEK composites. The results showed that the interfacial properties of CF/PEEK composites were improved after applying the sizing agent. Furthermore, the use of PEEK-COOH sizing agents resulted in an excellent transition layer between CF and PEEK, facilitating efficient stress transfer and even stress distribution.

Summary: Constructing conductive filler networks with high efficiency is essential for fabricating functional polymer composites. In this study, the researchers utilize the unrecognized geometric curvature of 2D sheets to break the efficiency limit of filler systems. They introduce the concept of hyperbolic curvature to mediate the incompatibility between 2D planar topology and 3D filler space, resulting in a highly efficient conductive path. The hyperbolic graphene framework demonstrates exceptional electrical and thermal conductive functions in nanocomposites. The study provides a solution to reconcile the incompatibility between 2D planar structure and 3D conductive path, presenting a geometrically optimal filler system for multifunctional nanocomposites and expanding the design possibilities of 2D sheets.

Summary: Introducing a segregated filler network can overcome the limitations of using graphene-based conductive composites due to high filler costs. In this study, polypropylene composites filled with randomly dispersed graphene nanosheets (GNPs) and a segregated GNP network were prepared and their conductive properties were investigated. The segregated structure induced GNP clustering, resulting in a lower electrical percolation threshold compared to composites with randomly dispersed GNPs. The fully interconnected GNP cluster network inside the composite contributed to achieving a thermal conductivity of 4.05 W/m & BULL;K at a 10 wt% filler content. Therefore, the introduction of a segregated filler network enabled excellent electrical and thermal conductivities at a low content of GNPs.

Summary: The surface of carbon fibers is modified by a sizing agent composed of sulfonated polyether ether ketone (SPEEK) and carboxylated carbon nanotubes (MWCNTS), which improves the interfacial binding between carbon fibers and polyetheretherketone (PEEK) matrix. The flexural strength and interlaminar shear strength of the modified composites are significantly enhanced by 74.2% and 84.2% compared to CF/PEEK composites without sizing agent. Coating with SPEEK-MWCNTS is confirmed to be an essential approach to construct an excellent interface between the reinforcement phase and thermoplastic matrix.

Summary: This paper investigates the effect of impact damage on the fatigue behavior of CF/PEEK-titanium hybrid laminates. A fatigue life model is proposed to predict the S-N curves of the laminates based on energy dissipation approach. The energy dissipation behavior of the laminates under different experimental conditions is analyzed through post-impact fatigue tests, and the correlation between impact damage and fatigue dissipation energy is determined. The validity of the proposed model is verified through fatigue tests under different stress ratios and impact energy levels.
