Studies on mechanical properties of brake friction materials derived from carbon fibres reinforced polymer composite

Friction formulation which is derived from combinations of carbon based materials including those which are present in nano scale are introduced to fabricate carbon fibers reinforced polymer composite to enhance the friction performance in this paper. Two samples of decided combinations of ingredients are prepared adopting the procedure of powder metallurgy method. Mold of cast steel is developed by welding and forging process for preparation of sample number 2, while plastic mold is developed for fabrication of sample number 1. Mixture is poured into plastic mold at room temperature after proper mixing and stirring for 20 min time and allowed it to cure for two days inside mold cavity to fabricate the Sample No.1. Similarly mixture is poured into steel mold and put into stir cast furnace for 10 min at temperature 180 degrees C and 15 Mpa pressure, then mixture is allowed to cure by removing out from stir cast furnace for 6 h and sample No.2 is fabricated. Test specimen from both samples are prepared and tested performing shore D hardness test and compression test following standard test procedure. Test results are reported which shows higher hardness and compression strength values for sample no.2 which is manufactured by application of pressure and temperature and validated by comparison with properties of commercial brake pad mentioned in the literature. In a nutshell, carbon based polymer friction composite is developed and characterization is done to check mechanical behavior of composite. (c) 2021 Elsevier Ltd. All rights reserved.
