“…Paper-based friction materials are typically synthesized via wet paper-making methods, using reinforced fibers and friction modifiers as the main raw materials to create preforms, which are then impregnated with binders and cured via hot pressing [1][2][3][4]. As a type of composite, paper-based friction materials can exhibit excellent performance not afforded by a single component through performance coupling among different components, e.g., a high and stable dynamic friction coefficient (μ d ), high torque transmission ability, low friction noise, and high wear resistance [5].…”

Paper-based friction materials are porous materials that exhibit anisotropy; they exhibit random pore sizes and quantities during their preparation, thereby rendering the control of their pore structure difficult. Composites with different pore structures are obtained by introducing chemical foaming technology during their preparation to regulate their pore structure and investigate the effect of pore structure on the properties of paper-based friction materials. The results indicate that the skeleton density, total pore area, average pore diameter, and porosity of the materials increase after chemical foaming treatment, showing a more open pore structure. The addition of an organic chemical foaming agent improves the curing degree of the matrix significantly. Consequently, the thermal stability of the materials improves significantly, and the hardness and elastic modulus of the matrix increase by 73.7% and 49.4%, respectively. The dynamic friction coefficient increases and the wear rate is reduced considerably after optimizing the pore structure. The wear rate, in particular, decreases by 47.7% from 2.83 × 10−8 to 1.48 × 10−8 cm3/J as the foaming agent content increases. Most importantly, this study provides an effective method to regulate the pore structure of wet friction materials, which is conducive to achieving the desired tribological properties.

“…At a nominal load of 20 MPa, relative contact areas of about 5 to 12% at maximum local surface pressures of about 700-2200 MPa are calculated. Ompusunggu et al investigate the influence of wear and decomposition on the friction behavior of a dry multi-disc clutch with organic friction lining by analytical calculation based on a modified GW-model [19]. At nominal loads of up to approximately 3 MPa, maximum relative contact areas of approximately 6.5 to 9.5% are achieved depending on the state of damage.…”

Friction behavior in a sliding contact is strongly influenced by the surface topography of the bodies in contact. This also applies to friction clutches. Even small differences in surface topography may cause significant differences in friction behavior. Thus, it is important to be able to characterize the micro-contact of the rough sliding surfaces, which are, in the case of a clutch, steel plate and friction material. One important measure for the characterization of the micro-contact is the real area of contact. Another important aspect is the contact pattern. The article introduces a method to implement a FEM (Finite Element Method) model from real surface measurements. Real surface topography of the friction pairing is considered. The simulation method is applied to different friction pairings and operating conditions. Computational results with rough and smooth steel plates, new and run-in friction linings, and different nominal surface pressure verify the model. In addition, the results on real area of contact between a steel and a friction plate are compared with published values.

“…Yagi (Yagi et al, 2015) studied the influence of microscale texture on friction properties of paper-based friction materials using the SAE#2 apparatus. Moreover, there are many researchers who have studied the friction properties with simulation methods (Ompusunggu et al, 2015;Wang et al, 2017). For example, Li (Li et al, 2015) developed a fuzzy comprehensive evaluation model and found that the comprehensive evaluation indexes are increased by 126-307 per cent for the samples with 4-15 Wt.% of carbon nanotubes (CNTs) compared with the sample without CNTs.…”

Purpose The purpose of this paper is to study friction and wear properties of three types of steels against paper-based friction disc, including 65Mn, 20#steel and 30CrAl, so as to obtain the appropriate working conditions for different friction materials in the transmission system. Design/methodology/approach Based on actual working conditions, pin-on-disc tests are conducted on a universal material tester. The two evaluation indexes, including average friction coefficient and variation coefficient, are introduced to analyze the different friction properties among three types of steel. Furthermore, the temperature-dependent wear pattern and wear depth are subsequently studied. Findings The results show that 65Mn is more suitable for working under heavy load and low velocity, but 30CrAl and 20#steel are suitable for working under light load and high velocity. Moreover, wear primarily occurs on paper-based material and peaks at about 325. Practical implications This research of different materials and friction property for friction pairs is helpful to improve the performance and prolong the service life of transmission systems. Originality/value Suitable working conditions of different friction materials are obtained, and the correlation between wear and decomposition in high temperature is verified.
