N2 - Helmet is a self-protection equipment designed to minimize injury during an impact to the head due to motocycle accidents. According to regulation of SNI 1811-2007, helmet must satisfy several criterions, such as penetration resistance and ability to absorb impact energy. In general, helmet could resistpenetration, but it might not absorb impact energy properly. Applicants might suffered head trauma for a while after collision. Impactenergy on helmet is absorbed by foam rather than the shell of helmet. The helmet which has a good penetration resistance and energy absorption normally is not lightweight. Users feel heavy and pain in the neck when wearing such helmet for rather longer time. This research developed a multiple reinforcement's composite material as an alternative materialfor helmet shell in order to obtain a lightweight helmet, which has penetration resistance, and good ability in absorbing impact energy. This research is started by simulating shell of helmet. The shell consists of epoxy-sisal fibers-hollow glass microsphere (HGM) composite andlaminated with carbon fiber on the external shell side. Simulation of penetration test and impact absorption are performed by following National standard procedures SNI 1811-2007. Depth of penetration that occured due to penetration is recorded during simulation of penetration. Meanwhile, acceleration is recorded during simulation of impact. Based on both simulations, a helmet configuration consists of one layer of carbon fiber and 4 mm of epoxy-sisal fibers-hollow glass microsphere composite thickness is selected. This configuration is satisfied regulation of SNI 1811-2007. The shell of helmet is unpenetrated - depth of penentration is 77.3%, and the unit helmet absorp the impact energy by reducing acceleration to 1305g.
