“…After fiber spinning, sizings [17] that contain the SCAs, as well as film formers and various surfactants, are applied to glass fibers. The sizing application produces a nanoscale region within the matrix surrounding the glass fiber referred to as the "interphase", since it is a complex interpenetrating-polymer network that can have graded material properties, different from the bulk polymer [18][19][20][21][22][23][24]. The sizing-induced interphase formed around glass fibers can have a lower glass transition temperature [25] and reduced elastic stiffness [26].…”

“…Carbon fiber (CF) is regarded as one of the most effective fibrous reinforcements for polymer composites, hence CF‐reinforced PEEK composites (CF/PEEK) have been widely used in several fields including aircraft engineering, automobile and mechanical industries . It has been recognized that the macroscopic mechanical performance is closely related to the interfacial properties between CFs and matrix, which plays an essential role in transferring stress from matrix to fibers .…”

In this work, the effect of preheat treatment on surface properties of carbon fiber (CF) and interfacial properties of CF‐reinforced polyether ether ketone (CF/PEEK) composites was investigated in detail. The sized T700SC CFs were preheated based on practical thermoplastic composites processing conditions. The obvious mass loss was obtained due to the sizing agent degradation. Fourier transform infrared spectroscopy and X‐ray photoelectron spectroscopy demonstrated that the concentration of sizing agents and activated carbon atoms decreased apparently for preheated fibers. Preheat treatment had negligible effect on tensile strength. Transcrystallinity structures were observed at fiber/PEEK interfaces using polarizing microscope and they had similar transcrystallinity density before and after preheat treatment. The microbond test was performed to determine interfacial shear strength (IFSS) between fibers and PEEK matrix. The IFSS increased from 40.16 to 46.32 MPa by 15.34%, which was against the trend of activated carbon atoms. Furthermore, the mechanisms of interfacial adhesion enhancement were discussed. The sizing layer became weak interface region because of poor chemical bonding between sizing agents and PEEK. Removing sizing via preheat treatment could enhance the interfacial adhesion. POLYM.

“…Dey et al [7] studied the influence of film formers on GF/EP microcomposites through the microbond test. The authors concluded that matrix compatible (reactive) film former may be more efficient than epoxy functionalized silane in the sizing in improving fiber/matrix adhesion.…”

This review summarizes the recent (from year 2000) advancements in the interphase tailoring of fiber-reinforced polymer composites. The scientific and technological achievements are classified on the basis of the selected strategies distinguishing between i) interphase tailoring via sizing/coating on fibers, ii) creation of hierarchical fibers by nanostructures, iii) fiber surface modifications by polymer deposition and iv) potential effects of matrix modifications on the interphase formation. Special attention was paid to report on efforts dedicated to the creation on (multi)functional interphase in polymer composites. This review is round up by listing current trends in the characterization and modelling of the interphase. In the final outlook, future opportunities and challenges in the engineering of fiber/matrix interphase are summarized.
