Composite Solutions for the Automotive Industry

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).

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 115 125 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.
