摘要

This study explores the mechanical properties and microstructure of basalt-kenaf reinforced polyester composites enhanced with cellulose fillers. The aim is to identify a sustainable, high-performance composite by varying fiber and filler proportions. Four compositions were fabricated: C1: 70% basalt, 30% kenaf, 0% cellulose C2: 60% basalt, 30% kenaf, 10% cellulose C3: 50% basalt, 30% kenaf, 20% cellulose C4: 40% basalt, 30% kenaf, 30% cellulose Mechanical testing followed ASTM standards. Among all, C2 demonstrated superior properties with tensile strength of 98.5 MPa, flexural strength of 132.4 MPa, and impact strength of 27.8 kJ/m2. The addition of 10% cellulose improved interfacial bonding and minimized voids, as confirmed by SEM micrographs. Increasing cellulose beyond 10% (C3 and C4) led to filler agglomeration and reduced bonding with the matrix, significantly decreasing mechanical strength. C4 showed a tensile strength of 74.2 MPa and impact strength of 17.3 kJ/m2. Overall, C2 is identified as the best-performing combination, balancing strength, toughness, and sustainability. This composite is especially suited for automotive interior components such as door panels, dashboards, and luggage compartments, where weight reduction and environmental impact are key concerns. The results confirm that moderate cellulose addition can enhance hybrid composite performance while maintaining eco-friendliness, offering a viable alternative to traditional fiber-reinforced materials. The experimental outcomes highlight the significance of optimizing filler dispersion and fiber stacking sequences to attain balanced mechanical behaviour. The study’s comprehensive evaluation under tensile, flexural, and impact conditions establishes valuable insight for future eco-efficient composite design and industrial material optimization.
