The reviews of quality characteristics of materials of design, models for design of pipes and pressure vessels and models for selection of materials based on desirability factor show that the mechanical and physical properties of material of construction such as density, yield strength, modulus of elasticity and Poisson’s ratio are relevant in oil and gas facilities design and production. This work focuses on the development of plantain fibre reinforced High Density Polyethylene (HDPE) to produce oil and gas facilities of moderate pressures. Matured plantain stems were gathered, retted, extracted, dried, treated, and modified. The tensile properties of untreated and treated fibres as well as their densities were determined. The fibres developed in this work exhibited very good mechanical properties in terms of tensile strength and density. The average maximum strength for mercerized fibre was obtained as 1024.986MPa and that of acetylated fibre as 2780MPa. These treatments improved the hydrophobic property of the developed material, giving fiber density as 0.132g/cm3. The tensile properties of Plantain fibre-HPPE composites were derived from tensile test results of fibres and the use of classical equations. The composite modulus was obtained as 27.82GPa at 50% volume fraction while 278.17MPa and 55.63MPa were obtained as composite ultimate and yield strengths respectively. The creep limit for designs in elevated temperatures for Plantain fibres-HDPE composites was evaluated as 92.72MPa. The physical and tensile properties of Plantain fibre-HDPE composites were optimized employing Taguchi robust design (TRD) and response surface method (RSM) to design experiments for production of test samples and products of oil and gas component such as pipes, pipe joints and tanks among others.
