Crack Path Selection in Adhesively Bonded Joints
… is to obtain an overall understanding of the crack path selection in adhesively bonded joints. Using Dow Chemical epoxy resin DER 331® with various levels of rubber concentration as an adhesive, and aluminum 6061-T6 alloy with different surface pretreatments as the adherends, both …

An Improved Method for the Fracture Cleavage Testing of Adhesively-Bonded Wood
This work describes the development of an improved mode I fracture testing procedure for adhesively-bonded wood, and demonstrates the sensitivity of this approach. The two significant improvements were: 1) the use of the flat double cantilever beam (DCB) geometry, which has been uncommon for wood …

Study of Durability of Epoxy Bonded Joints in Aqueous Environments
… and safety may be compromised as a result of wear and tear of fluid transporting pipe systems. Consequently, it is sometimes necessary to shut down the entire operation to fix the problem. Thus, it is worth evaluating other methods that can repair the damage for a temporary period without …

Time- and Temperature-Dependence of Fracture Energies Attributed to Copper/Epoxy Bonds
… energies corresponding to related, high-speed failure events. Work (or energy) is required to create new surface area—with associated dissipation events—during fracture, and this energy (for a given material system) is dependent on the speed of crack propagation, the locus of failure, and the …

Water based adhesive primers on aluminum substrates
The use of water based adhesive primers in enhancing the durability of aluminum adhesively bonded with epoxy was studied. The effects of the thickness of both the aluminum oxide surface layer and the primer layer on bond durability were established. 5052 aluminum alloy was oxidized by phosphoric …

THE DURABILITY OF PHENOLIC ADHESIVES
The main aim of thia programme was to study the superior durability claimed for phenolic-based adhesives, in hot humid conditions. The systems under study were the nitrile-phenolics AF-10 and AF-30 (3M), the vinyl-phenolic Redux 775 and the modified epoxide Redux 312 (Ciba-Geigy). The AF-30 …

An interdisciplinary study of cathodic debonding in elastomer/metal adhesive bonds
… study concerning the durability of adhesively elastomer/metal bonded joints in marine environments is reported. The generation of OH⁻ ions at the bondline due to an imposed cathodic current from an external source is suspected to be the predominant cause of failure. A surface …

Adhesive bonding of stainless steel :Sstrength and durability.
Adhesive bonding as an alternative method of joining materials together has many advantages over the more conventional joining methods such as fusion and spot welding, bolting and riveting. For example, adhesives can be used to bond dissimilar materials, adhesive joints have a high stiffness to …
