The paper presents the experiments performed in the laboratory and the results obtained on friction and wear behaviour of the composite materials for the manufacture of brake shoes used for driving and towed rolling stock. The tribological research of these samples made of composite material with organic components aimed to determine the influence of certain material factors and operating regime parameters on the tribological properties of the tested samples. The brake shoes made of composite materials oneusesto replace the conventional cast iron brake shoes, to reduce the noise. The future research will focus on finding composite materials with superior properties compared to the currently used ones, and lower costs.
The paper presents the results of the experiments on obtaining a composite material to be used in manufacturing brake shoes for the rolling stock. The aim was to replace the classical material used at present for the manufacturing of brake shoes: cast iron with a specially designed composite material. Six recipes have been tested and compared to a standard sample made of phosphorous cast iron. The wear trials carried out in laboratory conditions on the experimental test rods have led to results that entitle further experiments that implies the manufacturing of brake shoes made of the composite material in question.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
