Abstract
A flexural strength is one among the predominant factors for the polymer composites under perpendicular loading conditions against the axis of the member. In this study the flexural strength of Ethiopian Jute – Sisal hybrid polyester composite is investigated both analytically and experimentally. Composite test specimens have been prepared at various categories. They are based on different sequence of fibre layers: Jute-Sisal-Jute-Sisal (J/S/J/S), Sisal-Jute-Sisal-Jute (S/J/S/J) and Sisal-Jute-Jute-Sisal (S/J/J/S); fibres arrangement, based on orientation angle of fibres: [0°/45°/45°/0°], [0°/90°/90°/0°] and [45°/0°/0°/45°]; and based on concentration of fibers (weight ratio): [80% Polyester Matrix/20% Sisal/0% Jute], [81% Polyester Matrix/14% Sisal/5% Jute] and [76% Polyester Matrix/14% Sisal/10% Jute]. When comparing the results with different angle arrangement, [0°/45°/45°/0°] of fiber angled laminates is found to be most effective in flexural strength. And with different concentration of fibers in wt%, 10/14/76 [10% Jute, 14% Sisal and 76% Polyester Matrix] is found to be more satisfactory than the others in the flexural strength. From experimental result in sequence of fiber layers (S/J/S/J) has higher flexural strength than (J/S/J/S) and (S/J/J/S). From experimental result of jute/sisal polyester samples [0°/45°/45°/0°] has highest flexural strength which is 111.8 MPa and can resist maximum force of 469.5 N.
