Abstract
- Roughness metrics measured with stylus profilometry are commonly used to explain a floor's friction performance, yet these metrics inconsistently predict shoe-floor friction. While strong correlations have been shown for systematically modified flooring, the goal of this study is to address a gap regarding the predictive ability of these metrics across heterogeneous porcelain flooring products. The predictive ability of four roughness metrics on oily friction performance was assessed using 23 floors and 4 shoe designs. Roughness was moderately correlated with friction (r ranged from 0.374 to 0.760). These results are a reference point for future studies that aim to improve predictions using novel surface characterization approaches that include multiple scales. • Predictiveness of stylus-measured roughness on floor friction was evaluated. • Twenty-three floors and four shoes were included in the study. • Correlation coefficients between 0.374 and 0.760 were observed. • Incomplete predictive power motivates additional topography metrics. • Alternative metrics may improve predictions.
