Manufacture of fiber composite materials musa acuminate l. prepared by the randomized position with polymer matrix resin

Abstract

Composite is a system composed by mixing two or more different materials, in the form and composition of materials that do not dissolve each other. In general, the composite material is a material that has some properties that may not be owned by each component. This study aims to determine the effect of immersion banana fiber in NaOH solution, the composition ratio of the difference between the banana fiber to resin used and find the resistance of composite products produced against the pressure test and tensile test. This study begins with taking fiber banana followed by delignification process to remove lignin in the raw material, then molding composites made with a composition that has been set. The resulting composite will be tested durability to perform pressure tests (ASTM D 695) and a tensile test (ASTM D 638). To test tap on the position of the randomized to the concentration of NaOH 0%, 3%, 5% and 7% respectively, each for 53.716 N/mm 2, 43.184 N/mm 2, 81.724 N/mm 2 and 30.032 N/mm 2. For tensile test on an randomized position with NaOH concentration of 0%, 3%, 5% and 7% respectively, each for 21.519 M.Pa, 18.359 M.Pa, 31.033 M.Pa and 21.064 M.Pa.

تأثیر استخدام نسب خلط مختلفة من ألیاف الموز على الخواص المیکانیکیة للأقمشة المنسوجة

“…2) it is obvious that there is a direct relation between the elongation in warp direction and the ratio of banana fibres. This is due to the density of banana fibre is (1.35 g/cm 3 ) (17) , whereas the density of cotton fibre is (1.54 g/cm 3 ). So the fabrics which have more percentage of banana fiber in wefts increases the warp crimp leading to an increase in the fabric elongation in the warp direction.…”

Utilization of Parupuk Plants (Phragmites Karka) To Reduce Mercury Levels In Waters Former Of Diamond And Golden Mining

“…For diamond mining is usually passed on, it is they do for a living. In the mining activities are obtained materials [4,5] such as gold which follow to separate the gold by using mercury, causing the waters around the area is polluted by heavy metals mercury because of the flow of water directly into the river. Based on research [6], in the District Cempaka polluted waters, heavy metals that exceed the threshold of waste water quality standard is 0.02 mg/l according to PP 82 of 2001 on the waste water quality standards for mercury content.…”
