Copper Use Reporting Program Model Year 2003 Redesign

Presentation Transcript

  1. Copper Use Reporting ProgramModel Year 2003 Update Mark Phipps Ph.D. Product Development Manager Federal-Mogul Friction Products Brake Pad Partnership Stakeholder Conference June 22nd 2005

  2. Purpose of the Report • Track trends in the use of copper in OE automotive brake pads. • Monitor the BMC/PEC* members voluntary commitment to reduce the use of copper in the event that it is determined to be a significant cause of water impairment. • Provide information for the fate and transport modeling studies * BMC/PEC = Brake Manufacturers Council - Product Environmental Committee

  3. Data Strengths • Best Data Available • Data provided by the manufacturer (BMC/PEC members) • Coverage • Reliable information on approx. 40% of total car and truck sales in each model year • Trend Indicator • Indicates trends in the use of copper in brake pads

  4. Data Limitations • Coverage • ~60% of new cars sales not included • The data covers new cars and light trucks. It does not include usage in: • Aftermarket (replacement) brake pads • Motorcycles • Heavy duty trucks • Off-road vehicles • Rail cars • Results are not designed for total mass load calculations • Only one of the several inputs needed • Less than half of total new sales are included • Does not reflect regional variations in fleet mix • Regional driving patterns affect wear rates of brake linings

  5. Data Generation • Voluntary submission of copper content by BMC/PEC members • Proprietary information • Basis of “representative” wear debris sample • Vehicle selection (target is to sample ~40% of new car sales) • 1998 to 2001 • Top 20 best selling vehicles. • 2002and2003 • 20 of the top 25 best selling vehicles. (Actual Coverage: 1998 = 42.8% 1999 = 41.0% 2000 = 39.3% 2001 = 39.7% 2002 = 39.4% 2003 = 42.1%)

  6. Copper Monitoring Results • Trend in OE automotive industry towards larger brake systems and larger pads compared to previous model. • Evidence of a slowing of the shift in material type from semi-metallic to NAO/Low Steel friction materials. (Semi-metallic generally do not contain copper; NAO and Low Steel usually contain copper or copper compounds.)
