Interfacial tension, morphology and linear viscoelasticity behavior of PP/PS blends

open access: yesPolímeros, 1999
Blends of polypropylene and polystyrene compatibilized with styrene-butadiene-styrene (SBS) or styrene-ethylene/butylene-styrene (SEBS) copolymers were studied. The morphology of these blends was studied by Scanning Electron Microscopy.

Poisson's Ratio as a Function of Time in Composite Material of Viscoelastic Behavior by Depending on Creep Test [PDF]

open access: yesEngineering and Technology Journal, 2011
In viscoelastic behavior of composite material, such as those made of thermo-set polyester and one layer random fiber glass, the Poisson’s ratio is described in new function of time and stress. The relaxation stress is obtained experimentally to describe

High‐Temperature Nanoindentation of Metals: Assessing Thermal Drift, Frame Compliance, and Chemical Composition Effects on the Reported Mechanical Properties

open access: yesAdvanced Engineering Materials, EarlyView.
Do not let thermal drift and instrument artifacts deceive high‐temperature nanoindentation results. We compare classical Oliver–Pharr and automatic image recognition analyses across steels and a Ni alloy to quantify these effects. Accounting for artifacts reveals systematic softening with temperature, while Cr and Ni additions boost resistance ...

Optimization of the Production of Rubber Compounds Using Mathematical Models

open access: yesAdvanced Engineering Materials, EarlyView.
Rubber compounds were mixed in a batch internal mixer, and symbolic regression was used to derive mathematical models linking recipe and process parameters to ram path, torque, and mixing quality (incorporation, dispersion, distribution). Subsequent optimization with evolutionary algorithms identified operating conditions that reduce specific energy ...
