Abstract
Exploring the juncture of aerospace technology and material science, this study unravels the pivotal role played by carbon fiber reinforced polymer (CFRP) in advancing the industry. CFRP’s exceptional attributes - superior strength, reduced weight, and heightened durability - have positioned it as an indispensable material, revolutionizing aircraft design for enhanced performance, fuel efficiency, and sustainability. However, the reliance on polyacrylonitrile precursor (PAN), sourced from crude oil, prompts a critical examination of the material's supply chain resilience. In response to this challenge, the research delves into alternative precursors and matrices, presenting not only potential cost savings but also aligning with global sustainability objectives. Beyond precursor exploration, the study navigates the dynamic landscape of composite materials, considering the emergence of thermoplastic composites as promising alternatives. life cycle assessments underscore the environmental implications of
carbon fiber production and composite manufacturing, emphasizing the need for a holistic approach to materials evaluation. Further, the paper scrutinizes recycling methodologies for CFRP waste, reflecting the industry’s commitment to circular economy principles. As the aerospace sector strives for heightened sustainability, the study advocates for a nuanced understanding that transcends material performance, delving into the intricate environmental and economic considerations. The findings underscore the imperative for ongoing research and development endeavors, charting pathways for alternative precursors, refining recycling technologies, and innovating manufacturing processes to ensure the enduring sustainability of carbon fiber composites in aerospace applications.
