Comparative Analysis of the Effect of Fibre Architecture on the Tensile Properties of Sisal Fibre Reinforced Polyethylene Polymer Composite

This work investigates the effect of fibre architecture on mechanical properties composite laminates fabricated from natural sisal fibres reinforced with polyethylene polymer matrix. The main objective for this is to determine which architectural pattern produces best material in terms that can be employed use fabrication engineering components replace more expensive produced highly synthetic materials. Four patterns were chosen and tailor-made study namely;±45° angled ply, 0°/90° cross 90° 0°unidirectional plies. A five layered manufactured fabrics subjected tensile tests using Instron universal testing machine (model 4467) having 30kN load cell attached it an extensometer gauge length 75mm at a crosshead speed 200mm/min. result revealed laminate gives such as; elastic modulus, yield strength amongst laminates. It was followed by ±45° angle plied laminate, unidirectional lastly has lowest all tested. SEM micrographs fractured surfaces reveal failure modes are characterized mostly fibre-matrix debonding, delamination, splitting, cracking so on.
