Mechanisms of Moisture Attack in Adhesive bonds Exposed to High Humidity

July 23, 2008
Author(s)
Kar T. Tan, Christopher C. White, Cyril Clerici, Donald L. Hunston, Bryan D. Vogt, Sushil K. Satija, Joshua E. Goldman, Kristen L. Steffens
Studies have show that certain adhesive joints exhibit a dramatic loss of strength when exposed to humidities above a certain critical value. Although much is know about this effect, questions still exist. This study combines neutron reflectivity

ADHESION TEST METHOD FOR SPRAYED APPLIED FIRE RESISTANT MATERIALS

March 12, 2008
Author(s)
Christopher C. White, Kar T. Tan, Donald L. Hunston
Fire resistive materials are exceptional at providing an effective thermal barrier to structural steel from the heat flux from a fire, provided it is in close proximity to the steel during the fire event. The adhesion of the fire resistive materials is

E-Glass/DGEBA/m-PDA Single Fiber Composites: Interface Debonding During Fiber Fracture

October 1, 2007
Author(s)
Gale A. Holmes, R C. Peterson, Donald L. Hunston, Walter G. McDonough
In this paper, we examine the regions of debonding between the fibers and the matrix surrounding fiber breaks formed during single-fiber fragmentation tests. The materials used were E-glass fibers embedded in a matrix of diglycidyl ether of bisphenol-A

Challenges in Characterizing Sealant

September 14, 2005
Author(s)
Christopher C. White, Donald L. Hunston
Sealant is one of the very few major consumer products valued primarily for its rheological and adhesive properties. While, these materials may appear to be simple elastic solids, upon further examination, their behavior can be extremely complex. In this

Issues Relating to the Mechanical Property Characterization of Sealant

July 1, 2004
Author(s)
Christopher C. White, Donald L. Hunston
fective characterization of the mechanical properties of sealant requires knowledge of the non-linear complex viscoelastic properties. Additionally, all cured sealants, typically elastomeric materials, exhibit the Mullins effect, which also must be

The Effect of Movement During Cure of a Silicone Sealant

March 8, 2004
Author(s)
Christopher C. White, Donald L. Hunston
Movement of the building joint sealant during cure is thought to affect the fully cured mechanical properties. To examine this potential effect, a one-part silicone sealant was cured from 10 h to 168 h after sample creation before the onset of movement

Durability Gap Analysis for Fiber-Reinforced Polymer Composites in Civil Infrastructure

June 18, 2003
Author(s)
V M. Karbhari, Donald L. Hunston, B Benmokrane, T Juska, Roy S. Morgan, J Lesko, U Sorathia, D R. Reynaud
The lack of a comprehensive, validated, and easily accessible data base for the durability of fiber-reinforced polymer _FRP_composites as related to civil infrastructure applications has been identified as a critical barrier to widespread acceptance of
