Tensile and flexural properties of sisal fibre reinforced epoxy composite: A comparison between unidirectional and mat form of fibres

摘要

Natural fibres offer several benefits such as low density, low cost, environmental friendly and high specific mechanical performance. This work investigates the tensile and flexural properties of sisal fibre reinforced epoxy composite. This composite is prepared by using Hand lay-up method with 15, 20, 25 and 30 wt % of sisal fibres into epoxy matrix. Fibres are oriented in unidirectional as well as in the mat form. The tensile and flexural properties of sisal fibre epoxy composite both in unidirectional and in the mat form are found to be maximum at 30 wt %. It is found that the composite in unidirectional orientation of fibres gives better tensile and flexural properties in comparison to the mat form.
