Project ISF: Development of an In-Situ Fiber Reinforced Composite Part Rebuilding Process Utilizing Original Fiber with New Matrix Program DUIRI - Discovery Undergraduate Interdisciplinary Research Internship Term Fall 2023 Status Accepted Research Area Global Sustainability Description Mechanical recycling involves shredding the fiber-reinforced composite into small pieces, which are then reformed with additional binders. However, this process leads to a significant reduction in fiber length and overall performance, limiting its applicability. Thermal and chemical recycling methods offer the potential to extract continuous fibers from composites for reuse. However, processing these fibers to maintain their original form and orientation remains challenging. To overcome these challenges, a novel in-situ fiber reinforced composite part rebuilding process is proposed. This process involves removing the matrix while preserving the fiber orientation using a temporary mold capable of withstanding the matrix removal process. The extracted fiber layer is examined for damage, residue, and contamination. The retained fibers are evaluated for mechanical strength and bonding with the new matrix. Surface treatment techniques are explored to enhance fiber-matrix bonding if needed. Fresh matrix infiltration processes are studied through simulation and calculation to optimize resin transfer setup. Microstructural analysis using microscopy and CT scanning assesses fiber orientation, bonding, contamination, part thickness, and mechanical properties. The proposed recycling method allows for the rebuilding of composite parts by replacing only the devalued matrix while retaining the original fibers. This approach contributes to the economic and sustainable use of expensive fibers in industries such as wind energy and aerospace.
