Abstract
Scientists are actively exploring eco-friendly options to synthetic fibers because of their persistent pollution problems. Natural fibers, derived from plants and animals like bamboo, hemp, jute, and oil palm, are emerging as viable replacements for synthetics in making biodegradable, lightweight composites with enhanced mechanical characteristics. Chemical modifications have the potential to improve these properties, and treatments can change the structure of fibers to enhance mechanical interlocking. This review explores the characteristics of these natural fibers and their possible uses to promote sustainability and economic viability. The environmentally friendly qualities, cost-effectiveness, superior life cycle, and lightweight attributes are propelling the adoption of natural fibers in cement-based composites. A research study utilizes experimental and finite element analysis to create a sustainable cementitious composite reinforced with natural fibers. The choice of materials is critical to avoid premature failures and associated losses. In this study, the WASPAS method is applied to choose the most suitable natural fiber for durable composites from a selection of eight options based on six criteria. The results indicate that Basalt is the preferred choice, followed by flax and cotton.
