“…Therefore, the renewable based epoxy resin proved to have a good compatibility with carbon fibers and a high wetting capacity, which maximized the degree of molecular contact and made it difficult to separate the carbon fibers from the epoxy matrix. A good adhesion to the fiber–matrix interface has led to an easier load transfer to the carbon fiber reinforcement phase under shear loading, thus obtaining composite materials with good mechanical properties superior or similar to the reported CFRC composites based on DGEBA − and comparable with the industrial ones like Solvay Thornel P-55 Carbon Fiber/Epoxy Advanced Composite System = 55 MPa; Hexcel HexPly F522 Epoxy Resin, W3C282 Carbon Fabric = 26–62 MPa; and Hexcel HexMC C/2000/R1A Carbon Epoxy Molding Composite = 45 MPa. To validate the high quality of the fiber–matrix bonding given by ILSS results, the fracture surface specimens were further investigated by SEM.…”

Due to the global environmental concerns caused by the ever-increasing environmental impact, landfill materials, and CO2 emission, there is a critical need in the elaboration of sustainable composite materials. Advanced material composites used in the production of high-performance products to solve some of the most difficult engineering challenges are having a key role in decarbonization by their light weight, higher performance, and increasing durability. In this work, sustainable carbon fiber reinforced composites (CFRCs) have been engineered with an environmentally friendly epoxy resin derived from natural and renewable compounds employing an industrial feasible manufacturing protocol. The thermosetting resin with a biobased organic carbon content (BOC) of ∼77% was synthesized by combining a renewable based monomer, the triglycidyl ether of phloroglucinol (TGPh), with hexahydro-4-methylphthalic anhydride (HMPA). The developed CFRCs show high performance with high glass transitions T g > 350 °C, a high storage modulus ∼42 GPa, a high interlaminar shear strength ∼63 MPa, and a compressive strength ∼400 MPa. In addition, the outgassing tests show that both the resin and the CFRCs are compliant for space application. Moreover, the biobased CFRCs exhibit chemical recyclability, reprocessability, and excellent intrinsic flame resistance.

“…After modification using TA, the intensities of the peaks belonging to the stretching vibrations of OH and C O increased because of the successful modification of the fibers' surface by TA. 34 In the spectrum of CF-SiO 2 , the new peaks observed at 800, 1015, and 912 cm À1 are ascribed to the Si O Si symmetric stretching vibration, asymmetric stretching vibration, and Si OH stretching vibration, respectively. 17 Compared with the spectrum of CF-SiO 2 , that of CF-TA-SiO 2 showed additional peaks at 1125 cm À1 belonged to the stretching vibration of Si O C, indicating that the active Si OH obtained by TEOS hydrolysis was condensed with OH of TA to form Si O C. 16 TGA was used to characterize the effect of the TA and SiO 2 structure on the thermal properties of CF.…”

A carbon fiber‐tannic acid‐silicon dioxide (CF‐TA‐SiO2) reinforcement with a “diatom frustule‐like” structure was built via biomimetic mineralization to boost the performance of carbon fiber/epoxy resin (CF/EP) composites. As a bio‐based polyphenolic compound, TA was used to modulate the mineralization of SiO2, and the easy agglomeration of SiO2 was effectively avoided. The interfacial adhesion of the CF/EP composites was considerably heightened by improving the roughness and wettability of CF as well as by increasing the interfacial interactions between CF and the EP. Compared with the pristine composites, the flexural strength, interlaminar shear strength and interfacial shear strength of the CF‐TA‐SiO2/EP composites increased by 41.2%, 56.6%, and 50.4%, respectively. Moreover, the introduction of Si‐O‐Si and C‐O‐Si bonds at the interface led to a remarkable improvement in the hydrothermal aging resistance. This research provides a novel interfacial design for advanced composites with excellent interfacial properties, which broadens the application of these composites in hygrothermal environments.Highlights A “diatom frustules‐like” structure was successfully constructed on the CF surface. This biomimetic mineralization was simple and environmentally friendly. This method solved the problem of easy agglomeration of SiO2. The interfacial properties of composites were obviously improved. The hydrothermal aging resistance of composites was enhanced.

“…It was found that surface morphology was closely related to fiber wettability, and good wettability with robust interface was a prerequisite for strong interfacial interactions, which was essential for excellent interface properties [58]. Good infiltration is beneficial to the contact between the fiber and the matrix, which can reduce internal defects and improve the interface property of the composites [59]. The surface tension and polarity of two phases should be matched as much as possible to make adequate contact.…”

Carbon fiber reinforced composites have attracted lots of attention in many fields. However, on account of the poor infiltration of resin to carbon fiber, the weak interface performance between fiber and resin has been restricting the interface properties of composites. In recent progress, the review attaches more importance to the introduction of the third phase monomer, which mainly uses physical and chemical methods to assemble nanomaterials (such as carbon nanotubes, graphene, etc.) on the carbon fiber surface to modify the interface structure of the carbon fiber reinforced composites, and all of them have been demonstrated in this paper. Furthermore, the effects of introducing nanomaterials on the structure of the fiber/resin interface and the relationship between multi‐scale interface structure and properties have been investigated. It can be seen that the design idea of researchers mainly uses one or more theories to improve the interface properties of carbon fiber reinforced composites, such as transition layer, chemical bonding, mechanical interlocking, infiltration, diffusion, and adsorption. In brief, this work provides some novel insights for the preparation of carbon fiber reinforced composites with excellent interlaminar shear strength.
