“…In addition, they identified three chronological processes of diffusion, reaction, and phase separation which derive the interphase formation. In another study, Sonnenfeld et al [ 27 ] improved the damage tolerance of epoxy matrix composites through manufacturing of thermoplastic/thermoset multilayer composites using semi-crystalline poly-ether-ether-ketone (PEEK) and polyphenylene sulfide (PPS). They demonstrated that the introduction of a layer which was compatible with both thermoplastic and thermoset sections such as poly-ether-imide (PEI) increased the adhesion energy by a factor of 15.…”

Co-bonding is an effective joining method for fiber-reinforced composites in which a prefabricated part bonds with a thermoset resin during the curing process. Manufacturing of co-bonded thermoset-thermoplastic hybrid composites is a challenging task due to the complexities of the interdiffusion of reactive thermoset resin and thermoplastic polymer at the interface between two plies. Herein, the interphase properties of co-bonded acrylonitrile butadiene styrene thermoplastic to unsaturated polyester thermoset are investigated for different processing conditions. The effect of processing temperature on the cure kinetics and interdiffusion kinetics are studied experimentally. The interphase thickness and microstructure are linked to the chemo-rheological properties of the materials. The interdiffusion mechanisms are explored and models are developed to predict the interphase thickness and microstructure for various process conditions. The temperature-dependent diffusivities were estimated by incorporating an inverse diffusion model. The mechanical response of interphases was analyzed by the Vickers microhardness test and was correlated to the processing condition and microstructure. It was observed that processing temperature has significant effect on the interdiffusion process and, consequently, on the interphase thickness, its microstructure and mechanical performance.

“…It is thus envisioned that the 3-D printed CFRTSTP composite parts cannot fully compete in terms of the maximum achievable mechanical properties against the high-performance TS or TP composites manufactured by the classical methods (where the fiber volume fraction can reach 65–70%). However, it is nevertheless expected that the composite parts obtained through the CFRTSTP FFF method presented here will benefit from (i) the inherent high flexibility of 3-D printing technology, allowing for manufacturing of composite parts not easily obtained through classical manufacturing methods (see Figure 7); (ii) combined processing advantages of CFRP FFF technologies based on separate TS and TP matrix systems; and (iii) combined performance advantages of the TS-TP bi-matrix composite system (e.g., shifting the sudden brittle failure mode specific to TS composites, which is one of the main drawbacks of TS-based composites operating under severe loading conditions, toward the more progressive ductile failure specific to TP composite [32,33]).…”

A new paradigm in continuous fiber-reinforced polymer fused filament fabrication based on a thermoset-thermoplastic bi-matrix material system is proposed and proved. This totally new 3-D printing concept has the potential to overcome the drawbacks and to combine the advantages of separate thermoset and thermoplastic-based, fused filament fabrication methods and to advance continuous fiber-reinforced polymer 3-D printing toward higher mechanical performances of 3-D printed parts. The novel bi-matrix 3-D printing method and preliminary results related to the 3-D printed composite microstructure and performances are reported.

“…Among the numerous carbon fibre reinforced plastics (CFRP), thermoplastic (TP) composites offer several core advantages over the thermoset (TS) type ones for its excellent damage tolerance property and resistance to damage from impact. [1,2] Poly(ether ether ketone) (PEEK), a well-developed highperformance engineering plastic, is studied as a kind of aviation composite resin matrix material due to its excellent The CF sized by resulting PI had an increasement of interfacial adhesion between CF and PEEK. Analogously, PEI and PEKK oligomers were utilized through developing sizing agents by researchers, because they are also high temperature resistant resin matrix.…”

In order to improve the poor solvent resistance and poor temperature resistance caused by traditional sizing agents, crystalline poly(ether ether ketone) (PEEK) is introduced to the interfacial phases of carbon fiber (CF) reinforced PEEK composites by a soluble precursor named PEEK‐1,3‐dioxolane. By changing the soluble precursor molecular weight and concentration in the sizing solution, the content of PEEK coated on the CF fiber surface can be controlled and the different interfacial properties of the PEEK composites can be obtained. The results shows that, with this method, crystalline PEEK can be completely coated on the CF surface, and the interfacial shear strength of the PEEK composites increases from 43.42 to 83.13 MPa. Due to none of any soluble compounds in the PEEK composites, the interfacial layer is well preserved under organic solvents and hygrothermal conditions, and the interfacial shear strength (IFSS) of the PEEK composites maintained above 85.4% and 90.44%, respectively. Scanning electron microscope clarifies that the mechanism of interface enhancement comes from a better wetting of crystalline PEEK on the fiber surface. Additionally, the sizing system of this investagation has the potential commercial value because of no toxic reagent (such as 2,4,5‐trichloro‐1‐hydroxy‐benzene or concentrated sulfuric acid) is required during sizing.
