“…Park et al pre-treated a hydrophobic coating with plasma selectively and observed that by controlling the plasma treatment time the wettability and therefore the droplet spreading diameter of the ink can be controlled [128]. The functionalized surface of a plasma-treated substrate diminishes over time [129] and depends on various process parameters such as treatment time or gas [130]. Other methods for modification, such as surface roughening and abrasive, liquid chemical processes can be used to treat polymer surfaces as well [131].…”

“…[15][16][17] For overmolded thermoplastic composites, although hybrid components with comprehensive mechanical properties can be obtained via injection, there are disadvantages of lower interface strength and more process steps. [18][19][20] With regard to this phenomenon, some scholars tried to fabricate continuous fiber reinforced thermoplastics by injection molding process. Solorza-Nicolas et al [21] proposed to obtain woven glass fiber reinforced polycarbonate composites by injection compression molding technique, simulated the behavior of the polymer during the filling process, and studied the fiber orientation distortion with different laying modes.…”

Injection compression molding technique with self‐resistance electric heating provides an effective way to fabricate continuous carbon fiber reinforced thermoplastics (cCFRTs) components, but it may also have a significant impact on the properties of the components by inducing undesirable effects. It is necessary to understand the manufacturing process and minimize the introduction of undesirable factors. Thus, this work is to investigate the influence of process parameters (i.e., melt temperature, current intensity, holding pressure, and holding time) on the impregnation quality and mechanical properties of cCFRTs. The results show that fiber fabrics cannot be uniformly distributed in all cCFRTs, resulting in a thick polymer layer on the top of all cCFRTs. Moreover, the fiber distribution shows insensitive to the processing parameters. The increase of melt temperature, the decrease of current intensity and the extension of holding time are conducive to reduce void content and the frequency of macro void; While excessive holding pressure cannot reduce void content due to serious overflow of resin. Meanwhile, the effect of processing parameters on the mechanical properties and fracture morphology of the sample was also determined. The findings show that the flexural strength of the sample is 106.7 ± 0.8 MPa using the optimal processing parameters.

The forming interface is the weak link of thermoplastic composite complex structures. To explore the effect of polymer crosslinking on the failure behavior of thermoplastic composite remelting interface using “Preforming + Remelting bonding” process, the all‐atom models of different types of interfaces were established, and a molecular dynamics (MD) simulation was conducted on the uniaxial tensile failure process of the remelting interface. The failure behavior of the remelting interface with different preforming processes was tested to verify the correctness of MD simulation, and the influencing mechanism of polymer crosslinking reactions in the preforming stage to the remelting interface properties was clarified. The results showed that the yield stress of the uncrosslinked interface reaches 283.2 MPa and 16.0% and 50.6% higher than that of the unilateral and bilateral crosslinked interfaces respectively. The polymer crosslinking reaction during the preforming stage will reduce the interlaminar bonding performance. The interlaminar shear strength (ILSS) of the uncrosslinked interface is 87.46 MPa and 7.21% and 27.36% higher than that of the unilateral and bilateral crosslinked interface respectively, and only 3.95% lower than that of the non‐remelting sample formed by standard process. This research provides a new approach for predicting and analyzing the effect of polymer crosslinking on remelting interface properties of thermoplastic composite using “Preforming + Remelting bonding” process.Highlights The failure behavior of different thermoplastic composite remelting interfaces was studied. MD simulation was conducted on the uniaxial tensile failure process of the remelting interface. The influencing mechanism of polymer crosslinking reactions in the preforming stage to the remelting interface properties was clarified. It is effective to explore the failure mechanism of thermoplastic remelting interface by MD simulation.
