Abstract


The need of bullet-proof material of Indonesia until now commonly has been imported from other countries whereas a lot of natural materials potency in Indonesia that can be used as bullet-proof material. It can be proved that almost all regions in Indonesia had shield made from natural materials used during the war. Natural materials used to make shield were the wovens of fibers, namely from plants, cocoons, bark and vellum etc. If natural materials are combined with other materials, those will produce the natural composite material which has high strength and elasticity and deflection/deformation which is able to absorb high impact and can be fabricated directly into final form. Materials to be used in making this composite material as reinforcement were the sheets of pineapple fiber, silk fiber, palm tree bark and animal leather as well as constituent matrix using a resin. This research aimed to determine the mechanical properties and microstructure of reinforcement material of pineapple fiber, silk fiber, buffalo leather and bark palm. The mechanical test was done based on standard and microstructural observations through a Scanning Elctron Microscop (SEM). The results of the research show that Pineapple Fiber, Tensile Strength of 0,1888 kg / mm2 and Elastic modulus of 3.4 kg /mm2. Silk Fiber, Tensile Strength of 4,010 kg / mm2. Buffalo Leather, Tensile Strength of 7.292 kg/mm2 and elastic modulus of 2,902 kg / mm2. Bark Palm, Tensile Strength of 19.098 Kg/mm2, MOE 425.8 Kg / mm2, Compressive Strength of 14.425 Kg/mm2, Flexural Strength of 30.084 Kg / mm2 and MOR of 1041.1884 Kg/mm2. microstructure shows evenly on each material.
