Long-Term Development of Thermophysical and Mechanical Properties of Cold-Curing Structural Adhesives Due to Post-Curing

Julia De Castro San Roman Fest, Thomas Keller, Omar Moussa, Anastasios Vassilopoulos

The long-term changes in the thermophysical and mechanical properties of a cold-curing structural epoxy adhesive were investigated by accelerating the curing reaction by post-curing at elevated temperatures. Experimental data concerning the glass transitio ...

Experimental DSC-based method to determine glass transition temperature during curing of structural adhesives

Thomas Keller, Omar Moussa, Anastasios Vassilopoulos

A new DSC-based experimental method to efficiently establish the glass transition temperature, Tg, vs. curing degree, α, relationship for structural adhesives was developed. The method approaches the continuous Tg-α relationship with a trilinear curve esta ...

Time-temperature dependence of thermomechanical recovery of cold-curing structural adhesives

Julia De Castro San Roman Fest, Thomas Keller, Omar Moussa, Anastasios Vassilopoulos

The thermomechanical recovery behavior of a commercial cold-curing structural epoxy adhesive was investigated. Exposing the adhesive to temperatures above the glass transition temperature T-g significantly increased the latter although the curing degree in ...

Early-age tensile properties of structural epoxy adhesives subjected to low-temperature curing

Julia De Castro San Roman Fest, Thomas Keller, Omar Moussa, Anastasios Vassilopoulos

The early-age mechanical property development of structural adhesives during low temperature curing is critical for the outdoor construction of engineering structures, such as bridges or buildings. Construction of these structures is also carried out durin ...

Effects of low-temperature curing on physical behavior of cold-curing epoxy adhesives in bridge construction

Thomas Keller, Omar Moussa, Anastasios Vassilopoulos

The effect of low-temperature curing on the physical characteristics of a commercial cold-curing epoxy adhesive was experimentally and analytically investigated with a view to a potential application in bridge construction in winter. Curing at low temperat ...

Thermophysical and Thermomechanical Behavior of Cold-Curing Structural Adhesives in Bridge Construction

Omar Moussa

The use of the structural adhesive bonding technique is well established in the aircraft and automotive industries where, in most cases, joints can be fabricated indoors under controlled conditions. In the civil engineering domain, however, load-bearing st ...
