“…Carbon fiber-reinforced composites (CFRCs) are widely used in automotive industry, aerospace, sport equipment, and so forth owing to their low mass, superior mechanical properties, and high corrosion resistance. − Thermosetting resins are often used as CFRC matrices because of their simple preparation procedure, source abundance, and high performance. − However, thermoset matrices have insoluble and nonmelting properties because of their 3D permanent cross-linked network, which hinders the degradation and reuse of CFRCs. − Even worse, the disposal of thermoset matrices through landfill and incineration has caused serious environmental pollution and waste of resources . In addition, thermoset matrices are usually fabricated from petroleum-based products, which are not sustainable. − Therefore, the preparation of degradable bio-based CFRC matrices and the efficient recovery of high-value CFs from CFRCs are still challenging. , …”

The application of carbon fiber-reinforced composites (CFRCs) is limited owing to the difficulty of chemically recycling carbon fibers (CFs). To address this problem, we cured tung oil-based triglycidyl ester (TOTGE) with menthane diamine (MDA) in order to obtain a chemically degradable bio-based vitrimer matrix. The obtained vitrimer matrix could undergo a dynamic transesterification reaction catalyzed by the tertiary amines generated from the curing reaction. The TOTGE−MDA vitrimer matrix shows excellent self-healing performance, physical reprocessing, and shape memory properties. Meanwhile, CFRCs based on the TOTGE−MDA vitrimer matrix also exhibited excellent reprocessing, self-adhesive, and shape memory properties. The CFRC underwent rapid chemical degradation with ethanolamine at 90 °C. The performance of the recycled CFs was similar to that of the virgin CFs. This work provides an effective solution to facilitate the sustainable development of CFRCs.

“…Epoxidized vegetable oils may be used either non-modified or functionalized via epoxy ring opening with various compounds: amines, anhydrides, allylic alcohols, thiols, and α, β-unsaturated acids [ 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 ]. Thus, EVO was crosslinked with anhydrides and then used as obtained or combined with biofillers: keratin, lignin, spruce bark powder, hydrochar, lignocellulosic biomass, and flax woven fibers [ 25 , 26 , 27 , 28 ]. Carboxylic acids were also used as hardeners in the process of obtaining epoxidized thermosets based on vegetable oils [ 29 , 30 , 31 , 32 , 33 ].…”

The paper presents the synthesis and thermal behavior of novel epoxy resins prepared from epoxidized castor oil in the presence of or without trimethylolpropane triglycidyl ether (TMP) crosslinked with 3-hexahydro-4-methylphtalic anhydride (MHHPA) and their comparison with a petroleum-based epoxy resin (MHHPA and TMP). Epoxidized castor oil (ECO) was obtained via in situ epoxidation of castor oil with peroxyacetic acid. The chemical structures of castor oil (CO), ECO, and epoxy matrix were confirmed using FT-IR and 1H-NMR spectroscopy. The morphological and thermal behavior of the resulting products have been investigated. Compared to petroleum-based resins, castor oil-based ones have a lower Tg. Anyway, the introduction of TMP increases the Tg of the resins containing ECO. The morphological behavior is not significantly influenced by using ECO or by adding TMP in the synthesis of resins. The dielectric properties of epoxy resins have been analyzed as a function of frequency (1 kHz–1 MHz) and temperature (−50 to 200 °C). The water absorption test showed that as Tg increased, the percent mass of water ingress decreased.

“…The resin had a larger free volume in molecule structure, which was conducive to improving the toughness of the cured product. Di Mauro et al [26][27][28][29] recently reported a range of biomass fillers, such as flax woven fibers, norbornylized seed oils, and so on. The researchers found that the addition of biomass fillers increased the biobased content and increased the cost of the composites.…”

To enhance the fracture toughness of epoxy resin at low temperature, a secondary branched epoxy‐terminated silicone resin (ESR‐6) was synthesized and incorporated into bisphenol A epoxy resin at different contents. The structure of ESR‐6 was characterized by Fourier transform infrared spectroscopy and nuclear magnetic resonance (1H NMR), and the fracture surface of the composites was observed by scanning electron microscope (SEM) and atomic force microscopy. At room temperature and − 70°C, the maximum values of elongation at break were 15.78% and 12.55% with 10 wt% ESR. Compared with those of neat epoxy resin, the values of elongation at break of the composite were increased by 50.86% and 36.12%. The results of dynamic mechanical analysis also showed that the toughness of the modified resin had been improved. The SEM images of the fracture surfaces suggested that the fracture mode of the modified resin changed from brittle one to plastic one because of the addition of ESR‐6, which further confirmed the toughening effect of ESR‐6. These research results may provide a new strategy for enhancing the low‐temperature toughness of epoxy resins.
