Adapted the Mechanical Characteristics of Bio-Composite Sisal Fibres Material by Adding Aluminum Particles for Structure

Abstract

The e-bike structure is increasingly developing, especially in terms of design, its strength is around 300 MPa in a maximum application of around 160 MPa, as is the case with the scooter bike structure. The strength of sisal, which is a composite reinforcing component, is made from natural fiber from pineapple leaves, which is then mixed with hemp fiber and carbon fiber. In mechanical structure materials, apart from the material being expected to have high yield strength, it is also expected to have good ductility. The reinforcement is then mixed with hard epoxy resin, soft epoxy, and 9 µm aluminum particles which are then stirred for 12 hours, until smooth and even. Mathematically, the improvement in this bio-composite is quite significant, obtained from the addition of carbon fiber. The ductility of the material is obtained from sisal, hemp and ductile epoxy mixed with hard epoxy resin. Because the quality of crop yields greatly influences the quality of the fiber, future agricultural processes need to be provided with counseling. The sisal fiber is a leftover product from community farming in the Subang area (Indonesia). Research using local materials is still able to obtain strength reaching ~480 MPa so it is still good. In this research, tensile tests were carried out 3 times so that it was found that the fiber taken from the rope had the greatest tensile strength, reaching around 480 MPa.
