“…Additionally, shoe outsole metrics were selected to be low-cost in order to make the assessment accessible to practitioners (Table 2). For instance, a dynamic mechanical analyzer provides viscoelastic properties of elastomers (Wang et al, 2011), which may be linked to hysteresis friction (Lindner et al, 2004;Wang et al, 2011). However, this device can cost over $10,000 whereas a Shore A durometer costs about $30 (Table 2).…”

Traction testing of footwear is expensive, which may create barriers for certain users to assess footwear. This study aimed to develop a statistical model that predicts available coefficient of friction (ACOF) under boundary lubrication conditions based on inexpensive measurements of footwear outsole features. Geometric and material hardness parameters were measured from fiftyeight footwear designs labeled as slip-resistant. A robotic friction measurement device was used to quantify ACOF with canola oil as the contaminant. Stepwise regression methods were used to develop models based on the outsole parameters and floor type to predict ACOF. The predictive ability of the regression models was tested using the k-fold cross-validation method. Results indicated that 87% of ACOF variation was explained by three shoe outsole parameters (tread surface area, heel shape, hardness) and floor type. This approach may provide an assessment tool for safety practitioners to assess footwear traction and improve workers' safety.

“…Many attempts have successively been made to investigate parameters affecting properties of tire tread compound with the goal of achieving improvements of both rolling resistance and wet grip efficiency of tire [1][2][3][4][5][6][7][8][9][10][11][12]. Previous works have shown that rolling resistance and wet grip efficiency are closely related to dynamic viscoelastic behavior of tread compound and can be represented by the ratio of loss modulus to storage modulus (tan ) at high temperature (∼60 ∘ C) and low temperature (∼0 ∘ C), respectively [8,9,[13][14][15][16][17]. Carbon black (CB) has been widely used as the main reinforcing filler for tire tread compound because it offers greater processability with higher tire endurance, as compared with untreated silica.…”

This work aimed at investigating the effects of blend ratio between styrene butadiene rubber (SBR) and butadiene rubber (BR) and SBR type (E-SBR and S-SBR) on properties of SBR/BR tire tread compounds. Influences of these parameters on properties of the tread compounds reinforced by 80 parts per hundred rubber (phr) of carbon black (CB) and silica were also compared. Results reveal that hardness, strengths, and wet grip efficiency were impaired whereas rolling resistance was improved with increasing BR proportion. Surprisingly, the presence of BR imparted poorer abrasion resistance in most systems, except for the CB-filled E-SBR system in which an enhanced abrasion resistance was observed. Obviously, S-SBR gave superior properties (tire performance) compared to E-SBR, particularly obvious in the silica-filled system. Compared with CB, silica gave comparable strengths, better wet grip efficiency, and lower rolling resistance. Carbon black, however, offered greater abrasion resistance than silica.

“…The ability of filler particles to provide mechanical reinforcement was recognised in 1905 by using zinc oxide, but was quickly superseded as an “active” filler by carbon black in 1912 and silica in 1939 1 . There are advantages to using silica: for example, the wet skid resistance of silica-filled rubber can be higher than that of carbon black-filled rubber 3 and, as carbon black is generally produced from fossil fuels, silica may be regarded as a more environmentally sustainable alternative.…”

Rubber-filler composites are a key component in the manufacture of tyres. The filler provides mechanical reinforcement and additional wear resistance to the rubber, but it in turn introduces non-linear mechanical behaviour to the material which most likely arises from interactions between the filler particles, mediated by the rubber matrix. While various studies have been made on the bulk mechanical properties and of the filler network structure (both imaging and by simulations), there presently does not exist any work directly linking filler particle spacing and mechanical properties. Here we show that using STEM tomography, aided by a machine learning image analysis procedure, to measure silica particle spacings provides a direct link between the inter-particle spacing and the reduction in shear modulus as a function of strain (the Payne effect), measured using dynamic mechanical analysis. Simulations of filler network formation using attractive, repulsive and non-interacting potentials were processed using the same method and compared with the experimental data, with the net result being that an attractive inter-particle potential is the most accurate way of modelling styrene-butadiene rubber-silica composite formation.
