? 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
