1 Composite Solutions for the Automotive Industry

2 2 COMPOSITE SOLUTIONS FOR THE AUTOMOTIVE INDUSTRY Reduce weight. Reduce costs. Increase quality. Henkel offers composite solutions for the automotive industry. Composite matrix resins > Loctite MAX series including release agents for fiber reinforced components. Composite adhesives > TEROSON series for multi-substrate bonding and composite assembly. Process know-how and engineering > For Resin Transfer Molding (RTM) and assembly of composite parts. LOCTITE MAX and Series: For cost-effective and reliable composite solutions. 1. Semifinished part 2. Preforming Resin Transfer Molding (RTM) Process s for Composites 1. Semifinished part Carbon fibers or glass fibers are prepared for the resin transfer molding process. 2. Preforming The semifinished part is preformed mechanically. 5. Injection & curing The components of the composite matrix resin LOCTITE MAX series are mixed and injected into the mold. 6. Post-curing (optionally) To ensure a full cure, post-curing can be performed (e.g. 1 hour at 150 C).

3 COMPOSITE SOLUTIONS FOR THE AUTOMOTIVE INDUSTRY 3 LOCTITE MAX Composite Resin Solutions Designed for RTM with glass or carbon fibers enabling short cycle times suitable for automotive mass production. Process efficiency > Fast curing allows demolding after 1 to 5 minutes > Low viscosity ensures fast and efficient injection without stress to fibers > Process speed can be adjusted with additives Mechanics > Safe, controllable process with low reaction exothermy > Superior fatigue resistance under dynamics loads Application area > Structural components > Exterior components > Interior components Key Characteristics Characteristics LOCTITE MAX 2 LOCTITE MAX 3 Glass Transition Temperature Mold Release External External / Internal K1C 1,2 MPa m1/2 1,3 MPa m1/2 Paintability after demolding Tensile Strength 80 MPa 90 MPa Tensile Modulus 2,8 GPa 3,1 GPa 3.

Inserting preform into mold The preformed part is inserted into the prepared mold. 7. Surface The surface of the molded part is prepared for further processing. Henkel provides the ideal solutions for that area. 8. Bonding The finished part is assembled into place. Henkel provides the ideal solutions for every bonding application.
