Characterization of Lignocellulosic Roselle Fibre Epoxy Composites for Lightweight Structures
摘要
The current investigation is centred on the impact of inter-laminar fibre orientations on the physical and mechanical behaviour of lignocellulosic roselle fibre composites. For this research, the composites with 0°/90°, 0°/45° and ± 45° fibre orientations were developed via the hand layup method. All composites manufactured are of high quality and include fewer voids (1.28–3.30%). Results revealed that 0°/45° layered composite has better mechanical strengths. The bending and impact strength of the 0°/45° layered composite are 66.60 MPa and 14.01 kJ/m2, respectively. The flexural strength of 0°/45° layered composite is 17% higher than 0°/90° layered composite and 77% more than ± 45° layered composite. The impact strength of 0°/45° layered composite is 119% greater than 0°/90° layered composite and 55% higher than ± 45° layered composite. This material may be used for lightweight applications such as automotive door panels, automotive interiors, casings of electrical appliances, etc.
