In this work, carbon nitride (C3N4) powder was oxidized by the Hummers oxidation method, and oxidized carbon nitride (O‐C3N4) was obtained. Epoxy (EP) was modified with O‐C3N4, and then carbon fiber fabric/epoxy (CF/EP) composites were prepared by hand‐pasting molding. The O‐C3N4 greatly improves the wettability of EP resin, enhances the interface properties of CF/EP composites, and makes the composites have better mechanical properties. The interlaminar shear strength (ILSS) is increased from 51.75 to 59.68 MPa, the tensile strength is increased from 564.54 to 635.39 MPa, the bending strength is increased from 809.64 to 938.81 MPa, and the impact strength is increased from 73.48 to 84.84 kJ/m2. Meanwhile, the dynamic mechanical properties of composites are also significantly improved. The energy storage modulus is increased from 14.9 to 21.4 GPa, with an increase of 43.6%.Highlights Developing carbon fiber composites is conducive to industrial applications. O‐C3N4 effectively improves the mechanical properties of the composite. O‐C3N4 has the advantages of simple synthesis, low costs, and light color. O‐C3N4 is rich in oxygen‐containing functional groups.

“…Later a variant of nanocomposites appeared as multiscale composites containing at least two reinforcements at dimensionally different scales such as fibers with diameter in micrometer-range and tubes/particles/sheets with one of their dimensions at nanometer-range. Literature verifies the improvement in properties by following the strategy of incorporating multiscale reinforcements in composites [1].…”

“…The first being modification of fibers [25][26][27][28] and the second being modification of matrix. [29][30][31][32] Interleaving method can be used in laminated composites to minimize the interlaminar stresses and improve interlaminar fracture toughness [33][34][35][36] which results in resisting or arresting delamination. Materials having low modulus and high elongation were made use of as delamination resistors.…”

Determining the interlaminar shear strength (ILSS) of the composite laminates is vital for deciding their usage in any engineering applications. The matrix used and its curing characteristics are vital in deciding the ILSS of the composite. Present work deals with an experimental study on adhesive behavior, degree of flexibility, ILSS, and damage mechanism of the novel jute/rubber-based flexible “green” composite. The proposed flexible composites were prepared in three different stacking sequences, namely jute/rubber/jute (JRJ), jute/rubber/rubber/jute (JRRJ), and jute/rubber/jute/rubber/jute (JRJRJ), using compression molding technique. After determining the optimal curing characteristics of the proposed rubber-based matrix, the constituents are tested for their adhesive strength with the matrix which showed that rubber matrix system is compatible with jute fabric and natural rubber sheet. Composites are prepared and degree of flexibility for each stacking sequence is found out. Results pertaining to ILSS show that JRJRJ has better ILSS compared to JRJ and JRRJ. Fractographic analysis using scanning electron microscope reveals the mode of failure of the composites and the mechanism governing their failure. Fourier transform infrared spectroscopic study reveals the bonding between the constituents is good enough to be used in composites with flexibility.
