    Glass fiber-reinforced polymer composite materials, commonly used for industrial axial flow fan blades due to their high strength-to-weight ratio, are environmentally criticized for their non-biodegradability. This concern has prompted the investigation of eco-friendly alternatives, such as sisal and kenaf as natural fibers. Although they generally have lower mechanical properties than synthetic fibers, they offer advantages in terms of biodegradability, cost, and density. This study aims to evaluate the feasibility of partially substituting glass fiber with unidirectional natural fibers kenaf and sisal in a 14-layer GFRP axial fan blade through numerical simulation. The research employed a finite element method (FEM) to simulate tensile testing in accordance with ASTM D-638 standards. Several hybrid layer configurations were analyzed, focusing on the number and position of natural fiber layers replacing glass fiber, particularly the glass roving (GR) layers. The simulation investigated how these substitutions influence the overall tensile stress and elastic modulus of the composite blade structure. The findings suggest that this substitution does not significantly affect tensile characteristics but substantially improves the biodegradability of the composite, resulting in a more environmentally friendly material without compromising mechanical performance.
  • Improving Road Safety: Experimental Analysis of Brake Pad Performance Under Varying Speeds and Fluid Pressure

    Journal of Engineering United Kingdom, 2025
    Indonesia faces significant traffic safety challenges, with an increasing number of accidents each year, primarily due to brake system failures. Approximately 80% of accidents in both public and freight transportation are attributed to brake failure and driver fatigue. The contributing factors include poor brake system performance, wear, and overheating. This study addresses these issues by designing an experimental brake pad performance tester to assess Mitsubishi Colt L300 brake pads under operational conditions in a controlled laboratory setting. The study employs analysis of variance (ANOVA) to evaluate how rotational speed and brake fluid pressure impact brake pad performance, focusing on temperature and friction coefficient values. To ensure reliability and regulatory compliance, the experimental procedures in this study were conducted in accordance with Federal Motor Vehicle Safety Standard (FMVSS) No. 135. The results show that an optimum brake fluid pressure of 2.2 kg/cm 2 (215.7 kPa) yields the best stopping distance, with a coefficient of friction ranging from 0.7382 to 0.4659. ANOVA indicated that the rotational speed did not significantly affect the temperature ( p = 0.362), whereas the brake fluid pressure did ( p = 0.038). Both variables significantly influenced the coefficient of friction ( p = 0.001). These findings are important for the development of early warning systems (EWS) in vehicles, with the aim of enhancing braking system effectiveness and improving stopping distance performance.

  • Green density analysis on the process of 10% Cu-Sn powder compaction in development of frangible bullet
    Muhammad Burhanuddin, Widyastuti, Julendra Bambang Ariatedja
    Aip Conference Proceedings, 2021
    One of the developments in the frangible bullet in Indonesia is carried out by a workshop at the Department of Material Engineering, ITS. The product is produced by mixing, compaction and sintering of 10% Cu-Sn powder. One drawback is that the bullets begin to deform (or even disintegrate) when they are put into the cartridge case. It is suspected that the heterogeneity of the bullet density after going through the powder compacting process is the main cause. In this study, the discrete element method was used to predict the density distribution in the compaction process. The pressure is varied from 500, 700, and 900 Psi. Two types of frangible bullet geometries were introduced, namely, flat nose and full round. The bulk relative density distribution of frangible bullet was then calculated. There are repeating patterns for all variations. Areas close to a pressure source have a higher density than areas far away. This pattern indicates that the density is not fairly uniform. The lowest density of 1614.21 kg/m3 occurs at a pressure of 500 Psi for a full round nose bullet, and the highest is 1952.608 kg/m3 at a pressure of 900 Psi at the same bullet geometry. It can be concluded that there is a heterogeneous density after the compaction process, but relatively small. The resulting green density is still below the required density of frangible bullets.
  • Effect of surface treatment and cutting orientation to the changes in stents surface roughness
    Achmad Syaifudin, Julendra Bambang Ariatedja, Katsuhiko Sasaki
    Key Engineering Materials, 2020
    During the implantation process, an expandable balloon stent undergoes a change in mesh shape with a high strain rate. Permanent mesh shape changes to the stents indicate plastic deformation has occurred. On a micro-scale, plastic deformation has significant influence when interacting with the soft tissue of human blood vessels. This experimental study aims to investigate the effect of surface treatment and cutting orientation on the changes in surface roughness that definitely occurs when a stent deployed. To study the effect of surface treatment, two types of surface treatment were applied after surface polishing, i.e. etching and electropolishing. Surface polishing is carried out to enable microscopic observation. As for examining the effect of cutting orientation, the plate is cut in lateral and longitudinal orientation against the predicted-rolling direction of 316L sheet-type of stainless steel. An intermittent tensile test is conducted to obtain information about the changes in surface roughness. The surface observation is carried out three times on a similar surface of testpiece after reaching plastic deformation. The experimental study shows that the orientation of raw material has an insignificant effect on the changes in stent surface roughness. As for the surface treatments, electropolishing tended to decrease the tensile property of material.
  • Influence of specimen geometry to the tensile property of 316L stainless steel: Study case on raw material of stents
    Achmad Syaifudin, Julendra B. Ariatedja
    Aip Conference Proceedings, 2019
    Considering the raw material of balloon-expandable stent that usually obtained from tube-type geometry, it is still unclear how the multilinear isotropic model obtained from flat-type specimen can be used to represent the actual behavior of stent expansion. In this experimental study, non-standard sheet-type and tube-type tensile test specimens are prepared, which are made from stainless steel 316L. To assure equality of both chemical composition, the testing is carried out using Optical Emission Spectrometer. For the tube-type (axial and tangential), three pieces of specimens are prepared for the tensile test. The forces and yielded elongations are recorded in order to generate stress-strain relationship. The study indicated that the correlation between the stresses and the strains was not similar among various geometry of specimens. Tangential tube-type specimen experienced increasing of total strain faster than other specimen type. It differed significantly compared to a sheet-type specimen. A moderate correlation between the stress and the strain is obtained by a axial tube-type specimen. This investigation suggested a new value of material properties obtained from tangential tube-type specimen to be used in the FE study of balloon-expandable stent.Considering the raw material of balloon-expandable stent that usually obtained from tube-type geometry, it is still unclear how the multilinear isotropic model obtained from flat-type specimen can be used to represent the actual behavior of stent expansion.

  • Vulnerability analysis on the interaction between Asymmetric stent and arterial layer

    Bio Medical Materials and Engineering, 2019
    The utilization of Asymmetric stent for recovering atherosclerotic diseases, particularly non-symmetric obstruction, is a quite challenging breakthrough treatment. In terms of eccentric plaque, the non-uniform stiffness of arterial layer causes the increasingly complex issues of vulnerability. This study investigated the vulnerability of the interaction between the Asymmetric stent and the surrounding arterial layer using structural transient dynamic analysis in ANSYS. Four combinations of stent deployment, i.e. the Sinusoidal stent expanded by the offset balloon, the Sinusoidal stent expanded by the ordinary cylindrical balloon, the Asymmetric stent expanded by the offset balloon, and the Asymmetric stent expanded by the ordinary cylindrical balloon, are generated for this comparative study. Multilayer material properties from recent in vitro experiments are adopted for the surrounding arterial layer, such as a fibrous cap, lipid core, diseased-healthy intima, and diseased-healthy media. In order to address plaque vulnerability, the Cauchy stresses and Hencky strains are used for stress measure because of convenience in comparison with the uniaxial/biaxial tension test data. The location-specific threshold value from the diseased human carotid artery is adopted for rupture criteria. The simulation indicated that as regards the eccentric plaque, the plaque vulnerability is caused by the plaque shape and components rather than caused by the geometrical structure of the stent or balloon expansion method. Nevertheless, the non-symmetric inflation of balloon, which leads against the plaque, contributed to an increase in the vulnerability of fibrous cap of fibroatheroma plaque.
