Effect of Phenolic Resin and Alignment to the Quality of Prototype Composite Railway Brake Blocks

Abstract

The use of composites for railway brake provides several benefits among others: five times lighter than cast iron, install easily, lifetime five times longer, lower wear rate, cost to lifetime ratio better than other. Studies about composite brake have been done before. Optimum composition have been found also. But when the composition is applied to the manufacture of the prototype, the results are unsatisfactory. Therefore it needs advanced research abaout composition and procedure of process. In this studies, effect of phenolic resin and alignment would be researched. Results of that studies shows that addition of phenolic resin improve the quality of the prototype. Crack would be occured if position of the prototype was not alignment with the axis of dies.
