“…investigate the processability of carbon nanotubes (CNTs) PEEK composites in fused filament fabrication concluding that CNTs negatively impact the overall mechanical performance of the printed structures due to high melt flow and reduced diffusion between layers 6 . Jiang and co‐workers propose a new dispersion mechanism for multiwalled CNTs and PEEK, based on a solution processing method, to explain the improvement in mechanical data 7 . Consul and co‐workers direct their efforts towards carbon‐loaded PAEKs composites and using a bonding fusion model examine the bonding mechanisms and degree of bonding achieved by new PAEK materials designed specifically for AM by comparison with well‐established PEEK composite grades 8 .…”

“…It is still a challenge to prepare polyethylene (PE) nanocomposites with well-dispersed nanofillers due to the poor compatibility between nanofiller and the nonpolar PE matrix. Several publications describe attempts to disperse nanoparticles such as silica, , nanoclay, − CNT, − and graphene − in polyolefin matrices. Incorporation of compatibilizers, in situ polymerization, and polyolefin “grafting-to” nanoparticle surface have been studied.…”

Polymer nanocomposites containing well-exfoliated nanoplatelets have been shown to possess greatly enhanced physical and mechanical properties. However, it is still a significant challenge to achieve adequate exfoliation of 2D nanoplatelets in polyolefin matrices due to poor compatibility and associated entropic penalty between 2D inorganic filler and nonpolar polyolefin matrices. Grafting polyolefin chains onto the surfaces of an already exfoliated nanoplatelet is a simple, yet effective solution to this problem. The grafted polyolefin chains on the nanoplatelets can entangle and cocrystallize with the polyolefin matrix, preventing agglomeration. In this study, polyethylene (PE) grafted α-zirconium phosphate (ZrP), ZrP-g-PE, was prepared and blended with the PE matrix. The graft density of ZrP-g-PE was designed to maintain ZrP exfoliation during subsequent blending with the PE matrix. It was found that PE confined crystallization formed in ZrP-g-PE, resulting in the formation of PE crystal orientation perpendicular to the ZrP nanoplatelets. The usefulness of this study for preparation of high-performance polyolefin nanocomposites is discussed.

“…When the fiber content was higher than 30%, the bending failure of the SCF/PEEK layer occurred before the interfacial delamination failure. This emphasizes the influence of short carbon on interfacial bond and importance of improving the mechanical properties of composite components by means such as coating fiber with functional groups 26,27 and dispersing carbon nanotube 28,29 …”

A weak interface is formed between injected plastic and substrate during the injection over‐molding process. This study investigated the effects of mold temperature and melt temperature on the bond strength of injection over‐molded components, which were produced by injecting short carbon fiber reinforced polyether‐ether‐ketone (SCF/PEEK) onto the surface of woven carbon fiber reinforced PEEK (WCF/PEEK) laminate substrate. The results show that the interfacial laminar shear strength (ILSS) increases significantly from 15.8 to 50.0 MPa as the mold temperature raises from 190 to 260°C. The ILSS increases first and then decreases with melt temperature raises from 380 to 420°C, achieving a maximum value of 44.4 MPa at 410°C melt temperature. Crystallinity analysis and microscopic observations indicate different bonding modes are formed at the interface. The matrix tangling appears in the matrix enrichment area, interlocking, and tangling appear in the pits and weak tangling and cracks occur on the fiber surface. The mold temperature affects the ILSS by changing the crystallization property and the connection mode in the interface, while the melt temperature affects the ILSS by changing the area of the matrix entanglement. The relationship between the process conditions—interfacial microstructure—interfacial mechanical performance was discussed.
