Tensile Properties Comparison of Cassava Peel/Lycal, E-Glass 135/Lycal and Hybrid Cassava Peel+E-Glass 135/Lycal Composite with Hand Lay up Manufacturing Method

摘要

The use of composite materials in UAV development has increased significantly. The chosen of composite material for the UAV structure is due to the advantage of composite both from the strength and the light side of material that good for improving structure performance because it can be reducing the weight of the structure. Nowadays, research in material not only focus on reducing weight but also focus on reducing undegradable waste to environment. Tensile test has been carried out for Cassava Peel/Lycal composite and E-Glass/Lycal Composite. The comparison results showed that the cassava/lycal composite has modulus elasticity average value (3445,3 ± 0.36 MPa) smaller than Hybrid Cassava Peel+E-Glass 135/Lycal Composite (4704.28 ±0,67 MPa) and E-Glass 135/Lycal Composite (5916,5 ± 1,24 MPa). This trend is happened also for tensile strength value with average 44,63 ± 5,11 MPa for Cassava Peel/Lycal, 143,01 ± 15,82 MPa for E Glass 135/Lycal composite and 109.68 ± 7,05 MPa for Hybrid Cassava Peel+E-Glass 135/Lycal Composite. This result showed that the strength of E Glass 135/Lycal Composite still much bigger than Cassava Peel/Lycal Composite with but not really higher than Hybrid Cassava Peel+E-Glass 135/Lycal Composite. It means the cassava composite can't be the alternative material for UAV skin but it can be used for another part inside the UAV that not directly touching from outside impact.
