TiO2 nanowires/TiO2 film/ woven carbon fiber ternary hybrid: Significant mechanical and wear-resisting properties of phenolic composite

Self Cite

The metal organic frameworks (MOF-5) with nanoscale porosity and organicinorganic heterocyclic structure were chemically grafted onto carbon fibers by solvothermal for forming high mechanical interlocking composite architectures and releasing the interfacial forces, so as to obtain carbon fiber reinforced composite with excellent mechanical and tribological properties. With the multi-scale enhancement of MOF-5, the optimized tensile and bending strength of the composite increased by about 177.9% and 81.3%, respectively. Moreover, the friction coefficient was higher and relatively stable under the continuous wet friction condition, as well as the wear rate was reduced by 44.4%. The work suggests that the application of MOFs can be extended to the field of structural composites.

“…Nanoscale building blocks including carbon nanotubes (CNTs), 11 TiO 2 nanowires, 12 ZnO nanorods, 13 nanocellulose, [14][15][16] and graphene 17 were commonly grafted on the surface of fibers to enhance interfacial adhesion of carbon fiber reinforced composites. Wang et al 11 grafted CNTs on the carbon fabrics by chemical vapor deposition (CVD) to prepare the modified sample with a 45% increase of tensile strength.…”

“…Meanwhile, the friction coefficient of the composites displayed a 16.67% rising and the wear rate showed a 24.32% decline. Zhang and co‐workers 12 in‐situ grew TiO 2 nanowires on the surface of carbon fabrics after H 2 O 2 pretreatment. Related results indicated that the wear rate of the composites with the decoration of TiO 2 nanowires/TiO 2 film displayed a 60.8% decrease.…”

The limitation in the poor interface would severely affect the further development and application of carbon fiber reinforced composites (CFRP). Unique organic–inorganic hybrid architectures of MOF‐5‐NH2 and carboxymethyl cellulose (CMC) were established on the fiber/matrix interphase for promoting mechanical and tribological performances of the composites. The existence of above interfacial reinforced structure was in favor of generating abundant micromechanical interaction sites for enhancing mechanical interlocking. Meanwhile, high‐density chemical crosslinking networks played a positive role in elevating interfacial adhesion, further relieving stress concentration and hindering crack propagation. The tensile strength of CFRP‐2, CFRP‐3, CFRP‐4, and CFRP‐5 exhibited a significant rising of 27.18%, 30.64%, 27.75%, and 36.88%, respectively. The friction coefficient of MOF‐5‐NH2/CMC modified sample increased from 0.0953 to 0.1219, while the drop in the wear rate of the composites achieved 68.51%. This work provides an effective method for achieving the structure–function integrated design of composite materials according to the organic–inorganic interface enhancement of MOF‐5‐NH2/CMC.

“…Recently, many approaches for fiber treatment have been developed to improve interface performance by surface structure design. Among them, the most popular is to modify the fiber surface with nanomaterial, such as graphene, 7 carbon nanotubes, 8 TiO 2 , 9 ZnO, 10 and MXene, 11 and so forth, forming a nanoscale nanomaterial and micro-scale carbon fiber multi-scale hybrid structure to achieve mechanical interlocking between fiber and polymer matrix. Compared with other materials, carbon nanotubes are onedimensional tubular structure carbon nanomaterials with unique tribological characteristics, outstanding mechanical and thermal properties, which is the excellent choice acted as reinforcing phase for resin composites.…”

Multi‐walled carbon nanotubes/carbon fiber fabric multiscale hybrid materials for improving the mechanical and tribological properties of phenolic resin composites

et al. 2022

Multi‐walled carbon nanotubes (MWCNT)/carbon fiber fabric multiscale hybrid materials were prepared by grafting MWCNT on carbon fabric surface via heating grafted method to improve the mechanical and tribological properties of phenolic resin composites. Field emission scanning electron microscopy, Raman spectrometer, and X‐ray photoelectron spectroscopy were used to analyze the surface properties of carbon fiber. The results shown that the tensile strength of composites modified by 0.15 wt% MWCNT was 38% higher than that of unmodified composites. The wear rates decreased from 3.31 × 10−14 m3 (N·m)−1 for unmodified composites to 0.68 × 10−14 m3 (N·m)−1 for 0.15 wt% MWCNT reinforced composites. The reason was that the uniformly distributed MWCNT could increase interface interaction and mechanical interlocking between carbon fiber fabric and resin matrix.
