  • The objective of this work was to conduct an empirical search for correlations between viscoelastic responses and autohesive tack measurements from two trial series of variations of a model radial tire belt coat compound. The tack measurement values and a large volume of viscoelastic data were input into an efficient data analysis system to permit a search for simple linear correlations between sets of viscoelastic property variables and tack responses. Tack testing was conducted using a BFGoodrich Portable Universal Tester, manufactured by TechPro, Inc. Peak forces and tack energies were recorded as inputs for the correlation studies. Dynamic shear properties were characterized with an Alpha Technologies RPA 2000. Shear moduli characteristics (Gi, Gii, and G*) and tangent delta values were quantified for the compounds from the two trials and used as the viscoelastic inputs for correlations. The Pearson Product Moment Correlation approach was employed to measure the strengths of associations between the various viscoelastic properties recorded from the frequency and strain scans and the tack test data. Correlation calculations were conducted using data from six different frequencies and seven different strain levels. All testing was conducted during a period ranging from 48 - 52 hours after finish milling. All mixing, sample preparations and tests were conducted at Smithers Scientific Services laboratories in Akron, Ohio.
