Abstract

Kekuatan komposit sandwich dipengaruhi oleh sifat mekanis, tebal, kekuatan ikatan skin dan core. Kayu balsa adalah bahan core yang sesuai untuk aplikasi komposit sandwich karena rasio kekuatan dan kekakuan terhadap beratnya tinggi. Keunggulan lain adalah banyak ditemukan dan harganya murah. Pada penelitian ini, komposit sandwich dengan skin serat gelas dan core kayu balsa dibuat menggunakan metode hand lay-up menggunakan resin epoxy. Variasi arah serat anyam miring (45o/45o) dan lurus (0o/90o) serta variasi berat anyam 200 GSM, 400 GSM, dan 600 GSM diuji. Penelitian ini dilakukan untuk mengetahui mechanical bonding serat sandwich dengan menggunakan metode three-point bending dan penguiian impak. Hasilnya orientasi serat mempengaruhi tegangan lentur dan impak komposit sandwich. Orientasi serat lurus memiliki tegangan dan harga impak lebih besar daripada pada orientasi serta miring. Nilai tegangan tertinggi pada 400 GSM variasi orientasi serat lurus dengan nilai tegangan lentur 149,53MPa serta memiliki harga impak tertinggi yaitu 0,052 Joule/mm.

Abstract

This study aims to design and fabricate a speedometer cover for Yamaha Aerox and N-Max 155 motorcycles using 3D printing technology, guided by the House of Quality (HOQ) framework. The increasing consumer demand for motorcycle accessories motivated this research. A structured design process was implemented, beginning with a consumer needs analysis conducted through questionnaires and surveys to identify user expectations. These needs were systematically translated into technical requirements using the HOQ method. The design stage utilized 3D CAD modeling and 3D scanning to ensure accurate fitting to the speedometer unit, followed by prototyping using fused deposition modeling (FDM) 3D printing. The final prototype exhibited key consumer-desired attributes such as heat resistance, structural durability, and a secure fit. Results indicate that integrating the HOQ approach with digital fabrication methods effectively aligns product design with user expectations. This study demonstrates the potential for further development of customizable motorcycle accessories using a consumer-driven and technology-supported design process.

Abstract

The properties of filament are widely recognized as critical factors influencing the performance of fused filament fabrication (FFF) in 3D printing. Acrylonitrile Butadiene Styrene (ABS) is frequently utilized in this process due to its high strength, durability, and availability. Nevertheless, the characteristics of the filament are highly dependent on processing parameters, particularly extrusion temperature and cooling method, which directly affect its mechanical behavior and dimensional stability. The objective of this study was to evaluate the effect of extrusion temperature and cooling medium on the hardness of ABS filaments produced using a single-screw plastic extruder. Experimental procedures were performed at three extrusion temperatures, namely 180 °C, 200 °C, and 220 °C, with cooling applied by water immersion and by air using a blower. The results demonstrated that air cooling produced superior hardness values and more consistent dimensional stability compared to water cooling. The optimum condition was observed at an extrusion temperature of 180 °C under air cooling, which resulted in the highest hardness values along the filament length (95.63HA  average). These findings suggest that careful optimization of extrusion parameters, particularly the selection of an appropriate cooling method, is essential to improve filament quality for additive manufacturing applications.
