“…The excellent mechanical properties and thermal stability of the composite paper are attributed to the excellent properties of the raw materials and the structure of the alternating arrangement of organic–inorganic fibers in the composite paper. The ANFs have good binding properties to the BFs, and when the composite paper is subjected to stress, the crack deflection and bridging effect of the ANFs layer provide the composite paper with good mechanical properties and flexibility. ,− To better understand the enhancement effect of ANFs on the mechanical properties of paper, we observed the fracture morphology of the composite paper after tensile experiments by SEM and proposed a crack extension model (Figure d). When the crack deflects, it first extends along the ANFs layer for a certain distance, and when the stress acts on the BF, it causes the BF to fracture and slip.…”

The flame-retardant paper has gradually evolved into a necessary material in various industries as a result of the rising importance of fire safety, energy efficiency, and environmental preservation. Traditional cellulose paper requires the addition of a large amount of flame retardants to achieve flame retardancy, which poses a serious threat to mechanical quality and the environment. Therefore, there is an urgent need to develop inorganic fiber flame-retardant paper with good flexibility, high thermal stability, and inherent flame retardancy. Herein, inspired by the "brick-and-mortar" layered structure of nature nacre, we developed a layered composite paper with a unique alternating arrangement of organic−inorganic fibers by synergistically integrating environmentally sustainable basalt fiber (BF) and high-performance aramid nanofibers (ANFs) through a vacuum-assisted filtration process. The as-prepared ANFs/BF composite paper exhibited low thermal conductivity (0.024 W m −1 K −1 ), high tensile strength (54.22 MPa), and excellent flexibility. Thanks to its excellent thermal stability, the mechanical strength remains at a high level (92%) after heat treatment at 300 °C for 60 min. Furthermore, the peak heat release rate and smoke generation of ANFs/BF composite paper decreased by 44.6 and 95.3%, respectively. Therefore, the composite paper is promising for applications as a protective layer in flexible electronic devices, cables, and fire-retardant and high-temperature fields.

“…The presence of the dispersed nanoparticles can obstruct the path of a propagating crack, causing it to deviate or bifurcate. This process absorbs fracture energy, effectively slowing down or stopping further crack growth, and thereby enhancing the material's toughness and resistance to fracture [ 78 ].…”

“…It can be targeted to improve the interlaminar fracture toughness of composites. Carbon materials such as carbon nanotube (CNT), carbon fiber and graphene are ideal interlaminar toughening materials applied directly or made into films, non‐woven fabrics, etc., to be added to composite interlaminar plies to improve the IFT of composites 13–15 . Ma et al reported that pure carbon nanotube films increased the composite mode II IFT by 10.9% 16 .…”

[13][14][15] Ma et al reported that pure carbon nanotube films increased the composite mode II IFT by 10.9%. 16 Shin et al investigated the effect of CNT buckypaper as an interlayer toughening material on the fracture toughness of composites made of different forms of carbon fiber prepreg (unidirectional (UD) and woven (WN)), 17 and this study was shown that the addition of buckypaper increased the mode II IFT of UD laminate by about 45.9%.…”

In this paper, short carbon fiber (SCF) interlaminar toughened carbon fiber reinforced epoxy resin (CF/EP) composite laminates were prepared. The effect of SCF content on the mode II interlaminar fracture toughness (GIIC) and flexural properties of CF/EP composites was investigated. It was shown that the addition of SCF between the plies had an effect on the GIIC of the composites. When the SCF content was 10 g/m2, the GIIC increased from 1506.62 J/m2 to 1995.6 J/m2, which improved by about 32.46%. When the content of SCF was 5 g/m2, the flexural strength and flexural modulus increased by 36.92% and 98.48%, respectively, showing the best performance. The toughening mechanism of SCF was observed by SEM images as SCF debonding and pulling out from the resin and SCF fracture. The present study was also compared with our previous study on short aramid fiber interlaminar toughened CF/EP composites, and the test data and SEM images of the two experiments were compared to analyze the effect of different short fibers on the interlaminar toughening effect, which provides some reference for the selection of interlaminar toughening materials.
