Abstract

This paper investigates the possibility of use of pistachio shell flakes with flax fibres as reinforcements in polyester composites. Flax fibres were treated with 2% vol. NaOH to make it compatible with the polymer matrix. Physical and mechanical properties of the treated fibre at four different durations were determined and compared with the properties of untreated fibre. Fibre with high tensile strength and enhanced surface was selected for composite fabrication. Hand lay-up and compression moulding were used to fabricate the composites with 15% fibre weight fraction with pistachio shell flakes varying from 1 to 3 % by weight. Results indicate that addition of pistachio shell flakes reduced the tensile properties of the composites while their flexural and impact properties improved. Keywords – Flax fibres, Pistachio shell flakes, Polyester resin, Hand lay-up, Compression moulding, Mechanical properties.
