ABSTRACT
The use of SNI helmets is a mandatory requirement for using motor vehicle equipment. SNI helmets are generally made of polypropelene polymer. Composites reinforced with synthetic fibers cause biocomposites reinforced with natural fibers to become a major concern as a new environmentally friendly material. The purpose of this research is to determine the feasibility of sisal/carbon fiber reinforced composites as an alternative SNI helmet material that is more environmentally friendly. In this study, researchers examined the tensile strength, impact toughness, and density of sisal/carbon fiber composites. The composition of the fiber volume fraction is 25, 30, 35% of the composite mixture. The test results of the sisal/carbon fiber reinforced composite material show the density value of the polypropylene material is 1.135 g/cm3, while the density value of the sisal/carbon fiber hybrid composite with a volume fraction of 25%, 30%, and 35% is 1.184 g/cm3, 1.192 g/cm3, and 1.202 g/cm3. The tensile strength of the polypropylene material is 33.39 MPa, while the tensile strength of the sisal/carbon fiber hybrid composite with volume fractions of 25%, 30%, and 35% is 83.465MPa, 79.674 MPa, and 78.895 MPa, respectively. The impact strength of the SNI helmet material from polypropylene is 0.00972 J/mm2, while the impact strength of the sisal/carbon fiber hybrid composite with volume fractions of 25%, 30%, and 35% is 19.782 kJ/m2, 21.458 kJ/m2, and 28.294 kJ/m2. Based on these results, sisal/carbon fiber reinforced composite material is feasible to be an alternative material in making SNI helmets when viewed from the value of density, tensile strength, and impact strength.
