Calibrated thermal microscopy of the tool-chp interface in machining

January 1, 2003
Author(s)
Matthew A. Davies, Howard W. Yoon, Tony L. Schmitz, Timothy J. Burns, Michael Kennedy
This paper presents the results of calibrated, microscopic measurement of the temperature fields at the tool-chip interface during the steady-state, orthogonal machining of AISI 1045 steel. The measurement system consists of a nearly diffraction limited

CFD MODELING OF FIRE SUPPRESSION AND ITS ROLE IN OPTIMIZING SUPPRESSANT DISTRIBUTION

January 1, 2003
Author(s)
J C. Hewson, S R. Tieszen, W D. Sundberg, P E. DesJardin
Recent developments in suppression modeling for CFD codes are presented with an emphasis on fire suppression in cluttered environments. Suppression modeling is based on the ratio between the fluid mixing time scale and the flame chemical time scale. Flames

Chemistry and Properties of Phenolic Resins and Networks

January 1, 2003
Author(s)
Sheng Lin-Gibson, J S. Riffle
This book chapter emphasizes the recent mechanistic and kinetic findings on phenolic oligomer synthesis and network formation. The synthesis and characterization of both novolac and resole type phenolic resins and their resulting networks are described

Chemistry of Silanes Interfaces in Dental Polymers and Composites

January 1, 2003
Author(s)
Joseph M. Antonucci, Sabine H. Dickens, Bruce O. Fowler, H H. Xu, Walter G. McDonough
The performance and service life of glass- or ceramic-filled polymeric composites depend on the nature of their resin, filler and interfacial phases as well as the efficacy of the polymerization process. The synergy that exists between the organic polymer

Chitosan Hydrogels Crosslink Kinetics and Gel Properties

January 1, 2003
Author(s)
Sheng Lin-Gibson, H J. Walls, S B. Kennedy, E R. Welsh
Cure kinetics and network properties of biocompatible hydrogels prepared by the reaction of chitosan and a water soluble blocked diisocyanate have been measured using rheometry. The reactions follow the Arrhenius behavior from which apparent activation
