Resumo
Atualmente, a demanda por materiais estruturais leves e com propriedades mecânicas otimizadas
vem impulsionando a pesquisa em materiais compósitos. Os materiais compósitos de matriz
polimérica termorrígida, em especial compostos por resina epóxi e fibra de carbono (FC), têm
revolucionado as indústrias aeroespacial, automotiva e energia, e o aumento expressivo do uso
desses compósitos em setores de alta tecnologia gera, simultaneamente, uma quantidade
considerável de resíduos. Portanto, a reciclagem desse material de alto valor agregado torna-se
uma questão crucial para reduzir os resíduos gerados e promover a sustentabilidade. Este estudo
buscou analisar a evolução da reciclagem de compósitos de resina epóxi e fibra de carbono nos
últimos dez anos e identificar as tendências atuais. Os objetivos incluíram o mapeamento da
evolução e o crescimento das técnicas de reciclagem. O estudo utilizou uma abordagem de
pesquisa documental, com base no banco de dados Web of Science, analisando publicações
relacionadas ao tema no período de 2013 a 2023. A produção científica relacionada a materiais
compósitos cresceu 74% em relação aos anos de 2013 e 2023, com destaque para China e Estados
Unidos. O Brasil também demonstrou interesse crescente nessa pesquisa, com 9.404 publicações.
A reciclagem de compósitos é essencial para a sustentabilidade e a redução do impacto
ambiental, à medida que a indústria busca soluções mais eficientes e sustentáveis. A pesquisa e o
desenvolvimento de métodos avançados de reciclagem continuam a evoluir, impulsionando a
inovação tecnológica e econômica. Este estudo destacou a importância da reciclagem desses
materiais de alto desempenho na economia circular e na mitigação das mudanças climáticas.
Nowadays, the demand for lightweight structural materials with optimized mechanical properties drives research into composite materials. Thermoset polymer matrix composite materials, especially those composed of epoxy resin and carbon fiber (CF), have revolutionized the aerospace, automotive and energy industries, and the significant increase in the use of these composites in high-technology sectors simultaneously generates a considerable amount of waste. Therefore, recycling this high-value-added material becomes a crucial issue to reduce waste generated and promote sustainability. This study sought to analyze the evolution of recycling of epoxy resin and carbon fiber composites over the last ten years and identify current trends. Objectives included mapping the evolution and growth of recycling techniques. The study used a documentary research approach, based on the Web of Science database, analyzing publications related to the topic from 2013 to 2023. Scientific production related to composite materials grew 74% in relation to the years 2013 and 2023, with emphasis on China and the United States. Brazil also demonstrated growing interest in this research, with 9.404 publications. Composite recycling is essential for sustainability and reducing environmental impact, as the industry seeks more efficient and sustainable solutions. Research and development into advanced recycling methods continues to evolve, driving technological and economic innovation. This study highlighted the importance of recycling these high-performance materials in the circular economy and climate change mitigation.
