“…The matrix is usually a thermoset polymer, due to its better mechanical properties and better fiber-matrix adhesion, compared to thermoplastic polymers, but thermoplastics can be used as matrices as well. The most common polymers used as matrices are polyester, acrylic and epoxy resins [ 13 , 14 ]. Fibers enhance the mechanical properties of the composite material.…”

The rapid increase in the application of carbon fiber reinforced polymer (CFRP) composite materials represents a challenge to waste recycling. The circular economy approach coupled with the possibility of recovering carbon fibers from CFRP waste with similar properties to virgin carbon fibers at a much lower cost and with lower energy consumption motivate the study of CFRP recycling. Mechanical recycling methods allow the obtention of chopped composite materials, while both thermal and chemical recycling methods aim towards recovering carbon fibers. This review examines the three main recycling methods, their processes, and particularities, as well as the reuse of recycled carbon fibers in the manufacture of new composite materials.

“…On the other hand, have some advantages over thermosets, such as easy processability, better fracture resistance, ability to be easily joined using welding techniques, and, consequently, the possibility of easier recycling. 140,141 Smolén et al 142 used rCFRP as fillers in polyester resin. The authors noted that viscosity increased for compositions containing rCFRP particles compared to neat resin.…”

Carbon fiber (CF) reinforced thermoplastic and thermoset composites are on the rise for research and new technologies, consequently, the use by many industries for applications in diverse areas. The principal methodologies and technologies for reusing and recycling these composites and possible applications are reviewed based on available in the information in the existing scientific literature. This review aims to present the possibilities of recycling, reuse and application of these composites reinforced with CF. The composites show a high added value due to the cost of the raw material and the technology involved in its development, which deserves attention for its possible recycling, and thus, and closed-loop economy. Given the current concern for the environment, the future disposal of waste based on CF reinforced thermoplastic and thermoset composites deposited in sanitary landfills and incinerated are unlikely to continue. It is expected that with the new carbon-fiber reinforced-polymer (CFRP) waste management guidelines, most industries, and scientific research will develop viable and profitable methodologies for the reuse and recycling of this waste and that can be inserted into the economy for the manufacture of new components for the most diverse sectors automotive industry.

“…rCF is a commercially available product, and its reuse as reinforcement for new composite products has been extensively studied, and some reinforced products containing rCF have been commercialized and widely reported. [84][85][86][87] In this section, the discussion is particularly focused on the reuse of decomposed polymer (DP), as it is challenging and deserves more investigations. To date, there has been seen in a few studies in which the DP from chemical recycling is used as a reactive ingredient in new thermosetting polymer production.…”

Carbon fiber reinforced polymer (CFRP) composites are indispensable in a variety of applications, because of their high specific strength. CFRPs are generally constructed by carbon fibers as reinforcements and crosslinked polymers as binders. Due to the irreversible nature of the crosslinked polymers, CFRPs are neither repairable nor recyclable. Once the material is damaged or out of service, landfill or incineration is the typical way to deal with the waste. These methods take no advantages of the residue value of the waste and add burdens to the environment. To reduce waste and cost, it is desirable to develop effective recycling technologies to reserve the residue value of carbon fiber and polymer matrix. In the past decade, chemical recycling by cleaving the covalent bonds in a solvent has been considered as an ideal path for the recycling of CFRP wastes, because it has the potential to recover both valuable CFs and polymer matrix. In this review, the discussion is focused on the progress in the chemical recycling of CFRP. The primary matrix resin of CFRP discussed in this review is epoxy resin which is the most widely used polymer matrix. In addition, the challenges and outlook are provided.
