Page 12: Adhesives & Cements

Advantages Great Flexibility No Stress Concentrations Weight Reduction More Elegant Appearance Vibration Damping Stronger & Stiffer Structures

Page 13: Adhesives & Cements

Advantages Accuracy Bond is Continuous Joining Dissimilar Materials Delays Corrosion Improved Fatigue Resistance Easily Automated

Page 14: Adhesives & Cements

Disadvantages Durability of Joint Limited Inspection Techniques Change in Temperatures Limited Bond Time Difficult to Un-bond Preparation Environmental Considerations

Page 15: Adhesives & Cements

Special Considerations Ability to Wet the Plastic Chemical & Physical Interaction Stress Cracking

Anneal Parts Avoid Squeezing Fast-Curing Adhesives Unfilled Amorphous Materials
