| Summary: | In the growing environmental problems, the waste disposal and the dwindling of limited amounts of exhaustible resources have stimulated the use of green materials compatible with the environment to reduce environmental impacts. Therefore, there is a need to use natural resources in the design of products. Natural fibres seem to be a good alternative since they are abundantly available and there are a number of possibilities to use all the components of fibre-yielding crop; one such fibre-yielding plant is Agave Americana. The fibres yielded by the leaves and other parts of this plant can be utilized in various applications. The objective of the present work is to investigate the tensile properties of four varieties of hybrid composites. The composites include Agave Fibre-Glass composite (FB-GL-FB-GL-FB), Agave Fibre-Copper Foil Composites (FB-Cu-FB-Cu-FB), Agave Fibre –Aluminium foil composite (FB-Al-FB-Al-FB), and Agave Fibre-Copper foil-Glass-Aluminium foil composites (FB-Cu-GL-Al-FB). The Agave Americana fibre reinforced hybrid composites are produced through hand Lay- up technique. These fibres were treated with 7% NaOH (alkali treatment) and cured for 35 minutes at 85°C for better fibre matrix adhesion and tensile properties. The number of plies of fibre taken in each type of composite are three, and the total number of plies used in each hybrid composite are five.
Each of these composites is prepared in 00 orientations (i.e., fibres in parallel direction to each other) and 900 orientations (i.e., fibres in perpendicular direction to each other). It is observed from the results that, the tensile strength of FB-Cu-FB-Cu-FB
composite with 00 orientation is high (99.73 MPa) and that of FB-GL-FB-GL-FB composite with 900 orientations is low (13.73 MPa). There is a fairly low amount of difference in tensile strength (4 MPa) between the 00 and 900 orientations of FB-Cu-GL-Al-FB composite. It is also found from the results that, the percentage elongation is high (5%) for FB-GL-FB-GL-FB composite and low (0%) for FB-Cu-GL-Al-FB composite. |
