• Automotive Industry Trends & Implications to Adhesives
— Global Designs
— Fuel Economy (& weight reduction)
— Auto / Electronic Convergence
— Sustainability
• Multi Material bonding applications
• Summary & Long- -
Adhesives help manufacturers:
• Build structures that are stronger, stiffer, lighter
and better performing
• Make products quieter and more comfortable
• Solve difficult joining problems
Changing user needs and priorities
Challenge: stiffness & dynamic performance
Stiffness ~ Et (shapes)
~ Et 3 (flat panels)
Lower stiffness = degraded handling & performance
Solution: WELD BONDING
Increases stiffness & crash energy absorption
Decreases required spot welds or rivets
Al casting replaces multi-piece stamped assembly
Adhesive reduces stress on fastener and improves fatigue life
Adhesive prevents galvanic corrosion in mixed material assembly
• Reduce stresses in joints, which improves durability
• Enable gauge reduction of steel, which reduces weight
• Higher loads can be sustained, which improves crash and safety performance
Adhesives help manufacturers:
• Build steel structures that are stronger, stiffer, lighter and better performing
• Combine steel with other materials
• Make products quieter and more comfortable
