Optimal design of needlepunched nonwoven fiber reinforced epoxy composites using improved preference selection index approach
Viscose and polypropylene fiber-based needlepunched nonwoven fabric mat reinforced epoxy composites with varying mass per unit area (200, 400 and 600 g/m2) and varying fabric mat weight percentage (20, 30, and 40 wt.%) were fabricated.The manufactured composites were characterized for physical (density, void content), mechanical (impact energy, fle
