IMPACT ANALYSIS OF STRENGTH AND STRUCTURE OF MICRO FIBER COMPOSITES WITH VARIATION OF NATURAL FIBER DIRECTION
Reza Febrian Saputra Program Studi Mesin Otomotif Jurusan Teknik
ABSTRACT
One alternative material that is widely used as metal replacement material is a composite that has an advantage in against corrosion and his strength are at least equal to the metal material. The development of composites technology are now starting to experience a shift from synthetic fiber materials Composite materials Composite become as easy in his get natural fiber and has abundant resources that they do not wonder material industry has started to develop Composite natural fibers. Indeed, many natural fibers that are around us but not all natural fibers have the same power and therefore in this study will compare the strength Composite natural fibers using three different fibers include fiber midrib of the coconut tree, fiber hanging roots banyan tree and fruit fiber simpalak with variations fiber direction, the direction of the fiber used was 45 °, 0 °, 0 °, -45 °. 45 °, 0 °, -45 °, 0 °. 0 °, -45 °, 45 °, 0 °. And supported by the observation of microstructure on fiber density and fracture composite section. The result is average - the highest average price impact of a palm tree frond fiber composites amounted to 0.126 J / mm² fiber direction 45 °, 0 °, 0 °, -45 ° fiber composites hanging roots of banyan tree at 0.018 J / mm² ° fiber direction. 45 °, 0 °, -45 °, 0 ° fiber composites simpalak fruits of 0.038 J / mm² ° fiber direction. 45 °, 0 °, -45 °, 0 °.
