摘要

Given the rapid growth in the quantity of carbon fiber reinforced polymers (CFRP) waste, it is of great significance to develop efficient recycling methods for CFRP waste. This paper establishes an environmentally friendly closed-loop process from recovery to remanufacturing. Based on the principle of thermal activation with oxide semiconductors (TAOS), recycled carbon fiber (rCF) was obtained from CFRP waste. Subsequently, recycled carbon fiber-reinforced polymers (rCFRPs) were fabricated through additive manufacturing and wet alignment process. A comparative life cycle assessment (LCA) was conducted to evaluate the environmental performance of incineration, pyrolysis, and TAOS recycling. LCA strictly follows the ISO 14040/14044 framework and uses the CML 2001 method. GaBi-2000 software was employed to quantify the environmental impacts of background processes, with the Ecoinvent 3.8 database providing background data support. Compared with vCF production, rCF exhibited reductions of 85.82% in carbon emissions and 87.70% in energy consumption. Relative to pyrolysis, TAOS recycling reduced carbon emissions and energy consumption by 9.73 and 20.56%, with corresponding decreases of 12.51, 6.97, 11.28, and 10.33% in global warming potential (GWP, kg CO2-Equiv), abiotic depletion of fossil (ADF, MJ), acidification potential (AP, kg SO2-Equiv), and eutrophication potential (EP, kg Phosphate-Equiv).
