Engineering Adhesives – Types, Bonding and Design




Solid Print 3D


Engineering adhesives are used to join materials in mechanical, structural and manufacturing applications. Adhesive performance depends on the materials being joined, surface preparation, joint geometry, curing method, loading and service environment.

This section provides engineering reference information on adhesive types, bonding mechanisms and adhesive joint design, including natural, rubber and elastomeric, thermoplastic and thermosetting adhesives.

For structural applications, adhesive selection should consider not only bond strength but also shear, peel and cleavage loading, temperature, moisture, chemicals, creep, fatigue and the required service life of the joint.

Adhesive Design and Bonding


Adhesives

Engineering reference covering adhesive properties, terminology, joint design, loading, surface preparation and the selection of adhesives for mechanical and structural applications.
