Seat-belt webbing is an essential part of the automotive restraint system and has a decisive role in occupant protection during collision events. Traditionally, seat belt webbings are made from synthetic fibers such as polyester and polyamide of petroleum origin because of their high tensile strength, controlled elongation behaviour and resistance to abrasion and durability in severe mechanical and environmental conditions. However, rising environmental concerns, fossil resources depletion and global sustainability commitment have strengthened the research in recycled and renewable alternatives for automotive safety textiles. The introduction of sustainable materials in seat belt webbing is especially difficult because these materials are subject to strict international safety requirements and have to provide uniform long-term mechanical performance. This review gives a thorough analysis of sustainable and recycled materials for seat belt webbing such as recycled polyester, recycled polyamides, bio-based polymers and hybrid material systems. Material processing routes, degradation mechanisms, fatigue and creep behaviour, regulatory requirements, manufacturing challenges and life cycle environmental impacts are critically examined. The review also identifies key areas for research and future direction that focus on facilitating the large-scale adoption of sustainable seat belt webbing without compromising occupant safety.
