Multiple Fiber Technique for the Single Fiber Fragmentation Test

March 1, 1998
Author(s)
Chang K. Moon, Walter G. McDonough
The single fiber fragmentation test has been modified by embedding multiple fibers into matrix resin. During testing, we examined the interfacial shear strengths between the fibers and the matrix. In addition, the time-dependent nature of the fragmentation

Evaluation of Dental Adhesion and Durability by Means of the Microbond Test

February 25, 1998
Author(s)
Joseph M. Antonucci, Walter G. McDonough, Joy P. Dunkers
The phenomenon of interfacial of interphase adhesion is a critical factor in determining the strength and durability of multiphase dental materials. For example, the clinical performance of acrylic polymer based dental composites depends to a large extent

The Influence of the matrix Modulus on the interfacial Shear Strength Parameter

February 25, 1998
Author(s)
Gale A. Holmes, R C. Peterson, Donald L. Hunston, Walter G. McDonough
In composite structures, adhesion at the fiber-matrix interface is typically determined indirectly from experimental data and theoretical models. These models make varying assumptions about the fiber, matrix, and fragmentation process. Therefore, the

Workshop on Micromechanics Measurement Technologies for Fiber-Polymer Interfaces

May 1, 1997
Author(s)
Walter G. McDonough, Richard~undefined~undefined~undefined~undefined~undefined Parnas, Gale A. Holmes, Donald L. Hunston
The Polymers Division hosted the Workshop on Micromechanics Measurement Technologies for Fiber-Polymer Interfaces, jointly sponsored by NIST and the Textile Research Institute of Princeton, NJ, on May 28-30, 1997. Fifty researchers from industry, academia
