摘要

Abstract: High demand for polymer utilization in modern engineering applications, ranging from household products to advanced structural components, has increased environmental concerns due to the non-biodegradable nature of synthetic polymers. The present study investigates the fabrication and mechanical characterization of biodegradable green composites developed using woven Aloe vera, hemp, and flax fibers reinforced with barium sulphate particulate filler through the hand layup technique. The novelty of this work lies in the hybrid incorporation of comparatively less-explored Aloe vera fiber together with flax and hemp fibers to achieve a balanced combination of strength, flexibility, and sustainability in green composite structures. Mechanical characterization was carried out using tensile, flexural, impact, and hardness testing to evaluate the structural performance of the developed composites. Among all the fabricated laminates, the hybrid composite exhibited the best overall mechanical performance with a tensile strength of 74 MPa, flexural strength of 102 MPa, impact strength of 24 kJ/m², and hardness value of 80 Shore D. Scanning electron microscopy was employed to analyze the fiber–matrix interaction and fracture morphology of the composites. The microstructural observations confirmed improved interfacial bonding, uniform filler dispersion, reduced void formation, and effective crack-bridging mechanisms in the hybrid laminate. Due to their lightweight nature, cost-effectiveness, biodegradability, and enhanced mechanical behavior, the developed natural fiber composites demonstrate strong potential for sustainable automotive and transportation applications.
