From the soothing glow coming from the radio to the signaling blink coming from the taillight, a vehicle’s lighting system is critical to its look, feel, and safety. Lighting systems that incorporate materials from Avient’s portfolio of long- and continuous-fiber composites are more likely to maintain the integrity of their design Advanced Mobility Composite Structures

VALUE SOLUTION Improve safety and reduce costs with Gravi-Tech formulations When Gravi-Tech polymer metal composites are substituted for lead, manufacturers can avoid the regulatory, disposal and employee exposure challenges associated with lead. Several grades of Gravi-Tech composites used for radiation- shielding applications provide protections similar to traditional lead-based materials, yet these Gravi-Tech polymer-metal composites are 37 percent lighter. If the material is shear-sensitive, consult the material data sheet or processing guide for instructions to set recovery time • The cooling time should only be 1–2 seconds longer than the screw recovery time, unless dictated by dimensional stability or part thickness Minimize Clamp Pressure This step is done to reduce the amount of energy used by the machine

Long fiber thermoplastics (LFT) combine the structural integrity of metals with the lighter weight and cost-effectiveness of thermoplastic composites. Weight Reduction • LFT has lower density vs. metal, but still meets structural performance requirements • Lightweighting helps meet sustainability goals related to lower fuel consumption and extended vehicle range Design Flexibility • Injection molding allows for complex geometries and part consolidation • Advanced modeling and computer-aided engineering (CAE) tools for long fiber composites help validate and optimize part design APPLICATION BULLETIN COMPARING PRODUCTION COST DRIVERS Cast Metal Stamped Metal Long Fiber Composite Material typically used Aluminum Steel Various base resins based on environmental conditions Casting X Stamping X Injection Molding X Machining X Not typically needed as LFT is a one-step process Drilling X Welding X Surface Treatments X X po st -p ro ce ss pr oc es s MATERIAL CHARACTERISTICS Characteristic Long Fiber Composite Aluminum Steel Specific Gravity (g/cc) 1.03–1.71 2.76 7.8–7.9 Specific Strength (Strength-to-Weight ratio) Excellent Good Poor Stiffness Fair Good Excellent Toughness/Fatigue Excellent Fair Fair Creep Good Excellent Excellent Corrosion Resistance Excellent Good Poor Temperature Range Performance Good Excellent Excellent Cycle Time Excellent Good Poor Design Freedom (i.e., complex geometry, part consolidation) Excellent Fair Fair Raw Material Cost Poor Good Fair Total Production Cost Good Fair Fair pr od uc ti on pe rf or m an ce Avient offers a range of customizable long fiber reinforced structural material solutions and design support for your metal-to-plastic conversion projects
