Development of Pineapple Fibre and Biosilica Toughened Polyester Sustainable Biocomposite of Few Mechanical Properties for Automobile Application

This investigation focused to make use of pineapple fabric and peanut husk ash (PHA) biosilica particles to develop lightweight polyester bio-composites for automobile and inexpensive technological applications. In order to create biosilica particles from peanut husk, a thermo-mechanical procedure and an aqueous solution method are used and silane-surface treatment is performed on it. The uniqueness of the current work lies in the evaluation of the effects of PHA biosilica particulates added at various volume percentages on the mechanical (tensile, flexural, impact, hardness, ILSS and wear characteristics), fatigue, and ballistic characteristics of polyester composites reinforced with 45 vol. % pineapple fabric. The pineapple fabric and PHA biosilica particles treated with 3 vol. % silane exhibit the highest tensile, flexural, impact, and interlaminar shear strengths (128 MPa, 184 MPa, 5.68 J, and 27 MPa, respectively). While composites constructed with 5 vol.% PHA biosilica particles have a maximum hardness of 81 Shore-D, a minimum specific wear rate of 0.005 mm3/Nm, and a coefficient of friction (COF) of 0.48, respectively. Additionally, these composites exhibit good ballistic properties with the least penetration impact, and their maximum life counts of 38,830, 29,624, and 21,042 are obtained at UTS stress levels of 25%, 50%, and 75%. These polyester composites, which combine pineapple fabric with silane-treated PHA biosilica particles, should work well in a range of technical applications, including automotive parts like door and window frames, sporting goods, and domestic appliances.
