Friction and Wear Behaviour of Composite Materials Containing Organic Components

Abstract

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.

Organic modified epoxy resin. Tribologic aspects

“…To obtain optimal performance of the composite material, a broad variety of organic and inorganic modification agents are used [3]. The use of agents helps to improve the material by increasing the abrasion resistance and lowering the coefficient of thermal expansion [4]. Few studies, demonstrated the feasibility of using an organic acids as a novel ecofriendly curing agent.…”

Composite Materials Fabricated of Amorphous and Nanocrystalline Metallic Powders

“…The rapid pace of industrial development has led the specialists, in the technical fields of research and production, to create new materials (composites, ceramic powders, amorphous and nanocrystalline alloys, etc.). If ceramic composite and powder materials are old application [1][2][3][4][5][6][7][8][9], bulk amorphous and nanocrystalline alloys begin to outperform them, in terms of research and practical application, due to their unique physico-chemical and mechanical properties. The researchers have focused mainly on the discovery of new types of metallic glasses with excellent glass forming ability (GFA) so as to allow the production of bulk materials at low cooling rate by conventional casting methods.…”

Experimental Study of Sintered Friction Material with Coconut Fiber for Brake Pads

“…Keywords: brake pad, composite, organic materials, coconut fiber Current road safety requirements call for the development of new technical solutions for the main components of the vehicle. Their technical performances depend on the physical and mechanical characteristics of the materials which they are made [1,2]. Traditional materials used in automotive design have been studied over the time, so today is know their characteristics, their advantages and disadvantages.…”

“…Different papers have been reported in the scientific literature on the use of organic fibers in the production of composite materials, such as: pineapple, sisal, coconut shell, jute, palm, cotton, rice husks, bamboo, wood [2,[9][10][11][12][13][14]. Composite materials with coconut fiber have a wide range of applicability in countries such as Malaysia, Indonesia, Thailand, Sri Lanka.…”

“…They being used as building materials, marine ropes, fishing devices, furniture, household appliances [10]. Given the broad scope of applicability and because they are biodegradable and abundant resources in these geographical areas, their study has been the subject of more research, which have shown that this organic fiber has properties that approve its * camelia.bretotean@fih.upt.ro; Phone: 0732165956 application in use as a friction material, due to its high strength, low weight and superior properties to the products obtained [2,9,10]. In this work will be produced in the laboratory and characterize four recipes of composite materials with coconut fiber, designed to make the brake pads for small vehicles and average performance.…”
