Abstrakt: This research investigates the fabrication of natural fibre-reinforced laminate sandwich composites, emphasising the synergy between fibre type, polymer laminate, and fibre treatment. The grey relational and Taguchi techniques were employed to analyse the combinations of three natural fibres (snake grass, banyan, pineapple), three polymers (high-density polyethylene, high-impact polystyrene, polycarbonate), and chemical treatments (alkali, potassium permanganate, benzoyl peroxide). The compression moulding was adapted to produce the polymer sandwich composites with natural fibre reinforcements. The mechanical properties of the fabricated composites were measured using tensile and flexural tests. The contribution of the parameters to the outcomes was estimated using ANOVA. The comparison analysis suggests that the chemical treatment is the most influential fabrication parameter for controlling multiple response characteristics. The most critical process parameters for achieving the desired qualities (with values of 0.687, 0.663, and 0.655) are chemical treatments, polymer laminate, and fibre categories. Thereby, the three important fabrication parameters contribute to the advancement of sustainable composite materials.
