The urgent requirement for efficient recycling strategies in the wind energy industry prompted this study to explore the behavior of methanesulfonic acid (MSA) in the solvolysis of carbon fiber‐reinforced plastics (CFRP), as an alternative to standard solvents and acids. For the investigation, two layers of carbon fibers, infused with amine‐based epoxy through a vacuum‐assisted resin infusion process, were applied. The results showed that MSA was the most effective solvent for the solvolysis of CFRP, compared to other investigated common acids. The recycled products demonstrated satisfactory properties for both the matrix and fiber, which were comparable to those of the virgin materials.

“…It was shown that thermal treatment of the fibers results in improved interfacial interaction as well as higher strength-elastic properties of the PES based composites. Gebhardt et al [10] presented attempts to assess the potential for re-using carbon fiber fabrics recovered from recycling infusible acrylic thermoplastic carbon fiber reinforced polymer composites (CFRPs) in a universal manner, i.e. by combining with a wide variety of matrices to manufacture 2nd generation composite laminates by resin infusion.…”

Studies on weight reduction in aviation and space vehicles have gained momentum recently. Thermoplastic matrix composite materials are important alternative materials, especially due to their high specific strength, formability and recyclability. In this study, it is aimed to investigate the mechanical behavior of fiber reinforced thermoplastic composites for different fiber and layer configurations. Thermoplastic composite materials used in the study were produced by lamination technique. In composite production; Glass fiber and carbon-aramid hybrid fabrics were used as fiber, and polyethylene granules were used as matrix. Thermoplastic sheets were obtained by keeping polyethylene granules and woven fibers in the hot press for a certain period of time. The damage behavior of the composite test specimens under tensile load was tested for the number of layers and fiber type. As the number of layers increased, stiffness, damage load and deformations increased in thermoplastic composites. Using hybrid fabric instead of glass as fiber material increased the maximum damage load by 100%.

“…Moreover, the authors estimated the energy cost and analysed the presented methods economically. According to a previous article, Gebhardt et al [16][17][18] proposed a recycling strategy that enables the recovery of undamaged continuous fibres in the form of scrims and up to 81% of the Elium® matrix. Conducted tests proved that Elium®, epoxy, urethane acrylate and vinylester matrixes can be successfully used with recycled fibres without a significant drop in mechanical properties.…”

Carbon fibre-reinforced polymers (CFRPs) are commonly used in aviation, automotive and renewable energy markets, which are constantly growing. Increasing the production of composite parts leads to increased waste production and a future increase in end-of-life components. To improve the recyclability of CFRPs, new materials that fit in with the idea of a circular economy should be used as a composite matrix. One such material is a commercially available thermoplastic liquid resin, Elium® (Arkema, France). In this work, the authors investigated how the mechanical recycling process affects the properties of thermoplastic-based carbon fibre composites. CFRPs with neat Elium® resin and resin modified with 0.02 wt.% single-walled carbon nanotubes or 0.02 wt.% multi-walled carbon nanotubes were manufactured using the resin infusion process. Afterwards, prepared laminates were mechanically ground, and a new set of composites was manufactured by thermopressing. The microstructure, mechanical, thermal and electrical properties were investigated for both sets of composites. The results showed that mechanical grinding and thermopressing processes lead to a significant increase in the electrical conductivity of composites. Additionally, a sharp decrease in all mechanical properties was observed.
