In this research, the manufacturing process of the spar I beam profile using composite material were conducted. The design of the spar I beam profile were using the ± 45o and UD of carbon fiber. The process itself were used a hand lay-up prepreg and vacuum bagging method. It was found that for the manufacturing process by using hand lay-up prepreg and vacuum bagging were give a good result of the spar I beam made of composite material. The weight of the profile were 500 gr and the strength of the spar I beam profile give a good values, i.e. 11074 N. The strength to weight ratio of the profile were 22 N/gr. Finally there are several consideration of its manufacturing process to be concern to give a good properties of composite structure.
