Optimization and assessment of brake pad production parameters and organic Juniperus drupacea cone powder additive ratio using the Taguchi method

Abstract

In this study, an organic brake pad content was created to increase the overall tribological performance of the automobile brake system. Brake lining samples were obtained by hot molding method using juniperus drupacea cones powder which is not found in the literature in addition to barite, phenolic resin, fiber types (glass, carbon and basalt) and coke in the lining content. In order to determine the most ideal production conditions and content ratios, parameter combinations based on the L18(21 × 35) Taguchi orthogonal index were used according to the density, hardness, wear rate, friction coefficient objective functions. The density and hardness of the samples produced based on the orthogonal design were measured. A wear test was performed on a pin-on-disc type tribometer and the wear rate and friction coefficients were calculated according to the obtained values. Signal to noise ( S/N) ratio and ANOVA analysis were performed to determine the brake pad composition with the most ideal tribological properties. According to the results, the mixing time is 15 min., the molding temperature is 160 °C, the molding pressure is 100 MPa and the molding time is 15 min., have been found to be the optimum production conditions. In addition, it was observed that the density and hardness decreased as the amount of juniperus drupacea cone powder was increased. For this reason, it has been observed that the juniperus drupacea cone powder used for the first time in the brake lining composition can be used in lining content up to 25%, preferably up to 10% by weight.

Influence of ecological Juniperus Drupacea cone powder on mechanical and physical properties of fiber-reinforced composite friction materials

“…Then they were molded at 160 ºC, 100 MPa pressure for 15 min in a hydraulic. These production parameters optimized in the previous study [2] were employed in the current study. In addition, more detailed information about the production steps of powder and the hot pressing process was given in the previous studies [2,32].…”

“…These production parameters optimized in the previous study [2] were employed in the current study. In addition, more detailed information about the production steps of powder and the hot pressing process was given in the previous studies [2,32]. The images of the hydraulic press and the externally heated mold used in production, and the codes of CFMs produced are given Influence of ecological Juniperus Drupacea cone powder on mechanical and physical properties of fiber-reinforced composite friction materials in Fig.…”

“…Typical composite friction material (CFM) is produced by curing a polymeric binder, organic and/or inorganic components under heat and pressure [1][2][3]. The components' properties directly affect the mechanical, physical, and frictional performance of the final CFMs [4,5].…”

“…The components' properties directly affect the mechanical, physical, and frictional performance of the final CFMs [4,5]. As well as organic and inorganic fillers, the CFMs can be added with reinforcing materials such as basalt, carbon, glass fiber [2,6,7]. When the percentage by weight of the components used in producing such multi-component composite materials is selected appropriately, the improved structural properties expected from the final product can be obtained [6,8,9].…”

“…In the case of multi-component composites, it is known that the ratio of filler has a profound effect on the mechanical, wear, and physical properties of composite materials. However, no studies related to JDCP filled CFM in the literature except for the studies [2,31,32] that Aras was involved in. Therefore, the purpose of this study is to investigate the effects on density, hardness, liquid absorption, wear resistance, friction coefficient, the tensile strength of JDCP filled CFMs.…”
