Abstract:
This paper examines the current landscape of biodiesel blending for aviation applications, with a focus on technical The growing environmental consciousness and sustainability concerns have led to increased interest in bio-composite materials as alternatives to traditional synthetic fiber-reinforced composites. This study investigates the critical factors affecting the impact resistance of bio-composites, specifically focusing on fiber orientation and volume fraction effects. Natural fibers such as flax, hemp, jute, and kenaf have been extensively studied as reinforcement materials in polymer matrices, offering biodegradability and renewability advantages over synthetic fibers. The impact resistance of bio-composites is significantly influenced by fiber orientation angles, with unidirectional orientations typically providing superior performance compared to randomly oriented fibers. Volume fraction optimization plays a crucial role in maximizing impact energy absorption while maintaining structural integrity. This comprehensive review analyzes experimental data from various studies conducted between 2008 and 2017, examining the relationship between fiber orientation patterns, volume fractions, and impact resistance properties. The results indicate that optimal fiber orientations of 0°/90° and 45°/-45° configurations provide enhanced impact resistance, while volume fractions between 30-50% demonstrate the best balance of impact properties and processability. Understanding these relationships is essential for developing high-performance bio-composite materials for structural applications where impact resistance is critical.
