ABSTRACT
The enormous development of electric motor vehicle production has occurred nowadays, become one
of the efforts to solve the world energy crisis problem. Study of electric car body made by composite also
being improve to reach the car body where lightweight, flexible, affordable, yet have strength and toughness.
Research on the effect of orientation variations (30 o , 45 o , 60 o , and random) of fiber glass on the variation of
composition reinforce and matrix (1: 2.7 and 1: 4.4) to the impact strength of electric car prototype body is
done, and showed the highest impact strength values of variations in the composition of 1: 2.7 with the
random orientation fiber glass. For composites with random orientation of fibers with a mixture of
composition 1: 2,7 obtain impact strength values of 557.33± 38.68 kgm/m 2 , while in the composition of 1: 4.4
obtained value only 400 kgm/m 2 , whereas each of these impact strength values respectively are the highest
compared to the other uniform angle composites arrangement in each composition of mixture. Also
concluded that the impact strength values will increase with the addition of fiber composition on the
composite mixture.
