ABEXi BRAKES ASBESTOS-FREE Heavy Duty Brake Linings Deliver Long Life and More Value. Why Fiberglass The decision to use fiberglass as an asbestos substitute was the result of extensive laboratory testing which compared the numerous alternatives. Fiberglass was tested against Kevlar* aramld, cartoon and ceramic fiber materials to determine which offered the best combination of heat resistance, strength, stability, endurance and overall value. The test results below are for your own comparison. Coefficient of Friction Like ceramic material, fiberglass proved to have a high coefficient of friction. It's significantly higher than Kevlar4 aramid, plus it remains stable over the life of the lining. 7 Specific Wear Rate A relative characteristic, both ceramic and Kevlar4 aramid materials wore down considerably faster than fiberglass material. The result is long, dependable life, and without abrasive steel slag materials. Kevlar* a a registered trademark of E.I. DuPont OoNemoun & Company, Inc. The First Choice Based on these and othertests, fiberglass material was chosen as the best alternative to asbestos fiber. Using any of the other materials would have required either a ' sacrifice to performance, durability or strength. The obvious choice was fiberglass. Because at Abex, quality will not be compromised. 1600 1600 1400 1200 1000 Ict- 800 1 600 & 400 t. 200 mi o Heat Resistance A primary consideration for stability and wear, fiberglass withstood much more heat for a longer period ol time than carbon or Kevlar aramid. The clear choice once again was fiberglass. Reinforcing Value Since performance at high cost is unacceptable, calculations were made to determine the relative materia) values. Fiberglass proved to be 4 to 12 times a belter value than Kevlar4 aramid and ceramic materials respectively. 10000 9000 8000 7000 6000 5000 4000 3000 2000 c 1000 Flexural Strength The ability of a fibrous material to resist breakage is critical to its long lasting Integrity. Fiberglass is 50% stronger than the alternative reinforcements, which helps prevent rivet shifting and lining cracking while in service. Heat Resistance Value The relative heat resistance of fiberglass shows it is by far the best choice for obtaining structural integrity at a reasonable cost Friction Products Division 1827 Powers Ferry Road Building 20 Marietta, GA 30067 Printed in U.S.A.
