An tC industries Company Date: Hay 27, 1980 subject: NON-ASBESTOS MATERIALS From: To: B. Iwarsson Steve Conway Memorandum On Frank Herlihy's request, I am hereby submitting a summary on the status of our non-asbestos program. TECHNOLOGY First, It should be realized that the technology to produce friction materials with non-asbestos formulations has existed for many years. The problem has been to do so without a major price and weight penalty. The most common solution was based on a resin-bonded metallic formula tion; and, over the years, we have successfully produced blocks, strips and disc brake parts on this basis. However, until recently, the only serious commercial application of RBM materials was to be found in high performance passenger car disc brakes. This technology was developed by our European operation and later adapted for application in the U.S. Early in 1979, we developed a non-asbestos/non-metallie formulation for strip linings. After considerable dynamometer and vehicle tests, a revised version was introduced to the marketplace in 1980. In order to produce the same basic formula in blocks, we first had to solve some manufacturing process problems. This was accomplished in the Spring of 1980. The blocks are currently being dynamometer and vehicle tested by Abex as well as by Rockwell and Eaton. We expect to introduce these blocks in conmercial quantities later this year. ASBESTOS REGULATIONS The current limit of 2f/CM3 is in jeopardy. A new limit of 0.2f/CM3 has been proposed by NIOSH and OSHA. Although implementation might be delayed by court action, the end of asbestos as a raw material for friction products is in sight. ABEX-203 SPNY 003566 SCF-ABEX-2360
