Abstract
Komposit dibutuhkan dalam aplikasi kendaraan roda empat pada drive shaft sebagai penghantar torsi dan daya dari transmisi ke diferensial. Untuk menghindari konsumsi daya yang berlebihan pada drive shaft, maka disyaratkan drive shaft harus memiliki bobot yang lebih ringan dari bobot drive shaft konvesional (baja). Efisiensi penggunaan bahan bakar dapat meningkat jika bobot drive shaft dapat direduksi. Keuntungan lain yang diperoleh dari penggunaan drive shaft dengan material komposit adalah kemampuannya terhadap korosi.
Dalam penelitian melakukan perancangan mengenai penggunaan komposit serat karbon/epoksi sebagai drive shaft untuk kendaraan penggerak roda belakang kapasitas mesin 1329 cc memiliki torsi maksimum 120,62 N.m. Panjang 785 mm dan diameter 60 mm diambil dari referensi drive shaft baja SM45C. Metode perancangan simulasi menggunakan software finite element analysis (FEA) kemudian dilakukan pembuatan spesimen drive shaft komposit sesuai rekomendasi hasil simulasi.
Konfigurasi orientasi serat dan susunan layer terbaik adalah 45/45/0/0. Orientasi serat 450 memiliki karakteristik torsi yang baik. Orientasi serat 450 disusun pada bagian terluar (hoop) drive shaft, karena tegangan akibat torsi paling besar terjadi pada sisi luar. Orientasi serat 00 memilki kemampuan lebih baik pada kondisi tarik dan bending. Penggunaan drive shaft komposit serat karbon/epoksi dapat mereduksi bobot hingga 88%. Pada konfigurasi orientasi serat dan susunan layer terbaik ditemukan natural frequency meningkat hingga 38%.

Composite applications are required in four-wheel drive vehicles. The drive shaft as a transmitting power and torque from the transmission to the differential. To avoid excessive power consumption in the drive shaft, the drive shaft should be required to have a lighter than a conventional drive shaft (steel). Fuel efficiency can be increased if the weight of drive shaft can be reduced. Another advantage from the use of the drive shaft with a composite material is corrosion resistant.
In this study is using the composite carbon fiber/epoxy as a drive shafts for rear-wheel drive vehicle with engine capacity is 1.329 cc has maximum 120.62 N.m is torque. The length is 785 and is 60 mm diameter were taken from reference SM45C steel drive shaft. The design is using by finite element analysis (FEA) simulation method. Furthermore, the manufacturing process of specimens composite drive shaft to according simulation results recommendations.
Configuration of winding angle and stacking sequence is found the best is 45/45/0/0. The winding angle 450 has a good torque characteristics. The winding angle 450 are arranged on the hoop of drive shaft, because the stress is greatest torque occurs on outer side. The winding angle 00 have a better ability on tensile and bending conditions. The use of drive shaft composite carbon fiber/epoxy can reduce weight to 88%. The best configuration of winding angle and stacking sequence is increasing natural frequency to 38%.
