Design and Analysis of Carbon Fibre Composite MonorackArm for Motorcycle

Abstract

Monorack arm in the motorcycle is invented for the support of external topbox. However, load-bearing of the typical monorack arm made of common engineering metals is restricted to only 3 kilograms by the manufacturer in which exceeding this load may result in failure. Therefore, alternative materials such as carbon fibre composite receives the spotlight for this project. With that being said, the project objectives were to propose several conceptual designs of monorack arm which were used to analyze with finite element methods. Next, fabrication of carbon fibre composite sample was required to perform experimental analysis. Accordingly, several conceptual designs of monorack arm in regard to design considerations under static stress application were established. Besides, 2 types of samples were fabricated for experimental analysis namely plain weave woven fabric carbon fibre and twill weave woven fabric carbon fibre. Samples of carbon fibre composites were fabricated to possess a higher fibre volume fraction than the matrix to add fibre strength in the composite. Final conceptual designs of monorack made were computed for structural analysis using ANSYS Workbench. During the simulation of conceptual models, conceptual design 2 of epoxy carbon woven (230 GPa) wet was found to show better structural results in comparison to other designs using the same material. Lastly, tensile test was performed on the fabricated test specimens of plain weave carbon fibre and twill weave carbon fibre according to ASTM standards whereby favorable results were shown to plain weave woven fabric carbon fibre.

Pengaruh Panjang Serat dan Fraksi Volume Komposit Lidah Mertua Terhadap Pengujian Tarik

“…Sedangkan, hasil pengujian impak yang optimum dengan konsentrasi 20%:30%:50% sebesar 3,262 J/mm2. Penelitian ini menunjukkan bahwa serat daun lidah mertua dan serbuk gergaji dapat digunakan sebagai biomaterial penyerap bunyi [8].…”

Penelitian ini menunjukkan bahwa serat daun lidah mertua dan serbuk gergaji dapat digunakan sebagai biomaterial penyerap bunyi[8].Berdasarkan penelitian yang telah diuraikan rata-rata panjang serat yang memiliki kekuaatan tertinggi adalah 80 mm dan fraksi volume serat yang tertinggi adalah 20%. Artinya perlu dilakukan penelitian lebih lanjut untuk memastikan apakah semakin tinggi panjang serat dan semakin tinggi fraksi volume serat memiliki kekuatan yang lebih baik[9].…”

Synthesis and Characterization of Composite Materials with Enhanced Thermo-Mechanical Properties for Unmanned Aerial Vehicles (Uavs) and Aerospace Technologies

“…However, the prepared composites were brittle, elongation at break and impact strength was much lower while our research focuses on a different aspect of mechanical and thermal properties. Ridzuan & Jagan (2019) investigated the carbon fibres composite (CFC) for motorbikes' arms by utilizing hand layup process. However, there was no information regarding the epoxy used and curing time of epoxy was much longer to be 48 hours.…”

“…The researchers evaluated the effect of boron nitride reinforcement on the machinability of composite materials. The correlation of fibre orientation and resin, the effect of hardener over epoxy, inter-facial strength with respect to electrical, thermal, thermo-mechanical, inter-laminar fracture and vibration characteristics of composite with different types of the epoxy matrix were established by various researchers ( Batabyal et al, 2018;Ashori et al, 2019;Kaybal et al, 2020;Ekşi & Genel, 2017;Kaleemulla & Siddeswarappa, 2010;Minty et al, 2018;Muralidhara et al, 2020;Ornaghi et al, 2010;Rahmani et al, 2014;Ridzuan & Jagan, 2019;Lee et al, 2018;Vasudevan et al, 2018). However, no one has used LY5052 epoxy for 40, 50 and 60 wt% of carbon fibre composites.…”
