In the present work, a friction composite material which will be used for material of train
brake shoe was investigated to study the effect of ingredients on flexural strength. The Taguchi
method is used to measure relative effect of ingredients on flexural strength of composite. Taguchi L8 orthogonal array which consists of 7 factors with 2 levels each is applied to perform experiment.
Ingredients of friction composite were considered as factors or parameters and % volume for each factor was varied at 2 levels. Phenolic resin and barite (BaSO4) were not included as factor. Phenolic resin was always kept constant at 30 % volume and % volume of barite (BaSO4) was varied to compensate the changing of other ingredients amount. The results show that glass fiber and cast iron chip have significant effect on increasing of flexural strength of brake shoe composite. Conversely, NBR has significant effect on decreasing of flexural strength of brake shoe material. Cashew dust, Cu short wire, fly ash and graphite have insignificant effect on flexural strength. Cu short wire can’t play a role as reinforcement fiber in brake shoe composite because there is weak bonding between Cu short wire and matrix.
