Wood Sawdust as a Low‐Cost Filler in Whole‐Tire Reclaimed Rubber: Mechanical Characterization and Factory‐Scale Cost Analysis

Journal of Applied Polymer Science, EarlyView.
Whole‐tire reclaimed rubber is upgraded with wood sawdust, a carpentry by‐product available at no cost, across loadings from 0 to 20 wt%. At 5 wt%, tensile strength, elongation, hardness, viscosity, and water absorption all stay within commercial specification, and real factory data show an annual production saving near $62,000 with no capital ...

Monolithic Framework to Simulate Fluid‐Structure Interaction Problems Using Geometric Volume‐of‐Fluid Method

International Journal for Numerical Methods in Fluids, EarlyView.
A three‐dimensional fluid‐structure interaction (FSI) framework is developed using the geometric volume‐of‐fluid (VOF) interface capturing method and applied to assess largescale turbulent FSI interactions. The monolithic FSI framework is extensively validated, and despite the discontinuities across the interface, the FSI framework delivers stable and ...

Synergistic Effects of Phenolic Resin and Polymer Architecture on Crosslink Density and Damping in Poly(Epichlorohydrin‐Co‐Ethylene Oxide‐Co‐Allyl Glycidyl Ether) (GECO) Elastomers

Journal of Polymer Science, EarlyView.
Phenolic resin reduces crosslink density and alters the viscoelastic response of GECO elastomers. The magnitude of these changes depends strongly on polymer architecture. Damping performance is governed by the combined effects of network density and molecular structure, not resin content alone, providing a framework for designing advanced vibration ...
