NOVELTY - Preparing friction material involves dispersing 10-20 pts. wt. graphene oxide and 20-30 pts. wt. carbon powder in 160-200 pts. wt. water and then adding the dispersed material with 15-30 pts. wt. nano copper powder, nano silicon powder and 5-10 pts. wt. magnesium oxide powder. The obtained material is mixed and then the mixed material is subjected for ball milling and drying. The dried material is pressed into blank and then the blank is sintered in a high temperature vacuum oven to obtain friction material. USE - Method for preparing friction material (claimed). ADVANTAGE - The method enables to prepare friction material with good strength and friction coefficient.
