Abstract

Road bike adalah jenis sepeda yang mengutamakan kecepatan ketika digunakan. Rangka merupakan komponen utama sebagai penopang beban, maka harus aman, kuat, nyaman dan ringan, sehingga material carbon fiber cocok digunakan untuk rangka sepeda. Tujuan penelitian penulis adalah menentukan kombinasi arah serat terbaik pada rangka sepeda carbon fiber serta mengetahui letak daerah kritis dan lapisan kritis. Desain kombinasi arah serat terbaik adalah desain yang mempunyai faktor keamanan terbesar setelah dilakukan simulasi pengujian. Metode pengujian yang digunakan untuk pengujian desain rangka sepeda adalah pembebanan statis yaitu torsional loading, frontal loading, dan vertical loading. Dari data hasil pegujian yang dilakukan, data dianalisa menggunakan teori tegangan maksimum, teori tsai hill, dan teori tsai wu. Variasi yang dilakukan adalah arah serat karbon 0, 45, 90, dan -45, jumlah susunan lapisan 8 dan 6, dan jenis carbon fiber AS4 dan T800. Hasil yang didapat dari penelitian adalah desain arah serat karbon terbaik pada material carbon fiber AS4 dengan jumlah lapisan 8 lapis yaitu [0/90/90/0]s. Sedangkan hasil desain terbaik pada rangka sepeda material carbon fiber T800 adalah kombinasi arah serat [0/45/-45]s. "=============================================================================================" Road bike is the kind of bike that give priority to speed when used. Frame is the main component as a support load, then it must be safe, strong, comfortable and lightweight, so that the carbon fiber material suitable for bicycle frame. The purpose of the study authors is to determine the best combination of fiber direction on carbon fiber bike frame and locate the critical areas and critical layers. Design the best combination of fiber directions are those which have the greatest safety factor after the simulation testing. Testing methods to test the design of the bike frame is static loading which torsional loading, frontal loading and vertical loading. From the data results of test of that is done, the data were analyzed using the theory of maximum stress, hill tsai theory, and the theory of wu tsai. Variations are made of carbon fiber direction of 0, 45, 90, and -45, the amount of the composition of layers 8 and 6, and the type of AS4 carbon fiber and T800. The results obtained from the research is the design direction of the best carbon fiber in AS4 carbon fiber material with a number of layers of 8 layers is [0/90/90/0]s. While the best design results in material of carbon fiber bike frame T800 is a combination of fiber direction [0/45 / -45]s.
