Biomass fibers are promising materials for applications in modern vehicles. They have great economic and ecological significance, as well as a great potential in the fabrication of composite materials due to the relatively high level of strength and rigidity, low density, availability, recyclability, and biodegradability. In this context, the focus is on the development of automotive brake pad materials from sustainable sources. This work refers to the investigation of the behavior of composite materials made of biomass fibers, phenolic resin, graphite and aluminum oxide. These materials are intended to be used for brake pads on automobiles with moderate efficiency. For this purpose, three recipes of composite materials with different percentages of coconut fiber and wood powder were developed in laboratory. The physical and mechanical as well as functional properties of these composite materials with varying amounts of biomass fibers are examined in this paper.

Abstract Hot rolling cylinders are the most important machine parts in plastic deformation equipment. They are taken out of operation due to breakage caused by the predominant action of thermal stresses which cause accidental breakdowns of rolling mills. In view of these aspects, the question arose is to knowing the nature of these stresses, as well as their evaluation. This paper will experimentally determine the mechanical and thermal stresses that arise in the process of plastic deformation of hot rolling cylinders. The purpose of this paper is to evaluate the thermal stresses and compare them with the mechanical ones, as well as to highlight their influence on the thermal fatigue phenomenon. The study shows that the stresses in rolling cylinders are cyclical and occur at each rotation of the cylinders. The thermal stresses are mainly the result of the action of symmetric and asymmetric temperature fields. The overall action of thermal stresses presents an aspect of destruction of the surface layer that characterizes the effect of thermal fatigue phenomenon. The separation of the temperature fields that produce thermal stresses in symmetric and asymmetric and their experimental confirmation represents the originality of the research presented in this paper.

Abstract The friction material used for the brake pads should have a low wear rate, outstanding thermal stability to hold the braking properties of the vehicle and coefficient of friction should constant under different operating conditions which include loads which applied, temperature, dry or wet braking environment and speed. Due to this reason, every newly developed friction material’s fabrication should undergo a series of experimental tests to evaluate the friction as well as wear properties. In this article a study of frictional and wear behavior of friction material for ecological brake pads of road vehicles discussed. In the formulation of the friction material shells as a filler, a small amount of metal, silicon carbide, graphite, resin and hexametiltetramine were used. The main objective of the paper refers to the investigation of the impact of the working regime on friction material’s tribological characteristics. In this sense, were studied the evolution of the coefficient of friction and the thermal field at the contact surface between the friction couplings, the influence of load on the friction coefficient at different speeds and the influence of load on wear rate at a constant speed. The knowledge of the functional properties of the newly developed friction material produced in the laboratory provides the possibility of pertinent assessments regarding the durability of the brake pads during operations, as well as on the quantity of wear products released into the atmosphere. The results concluded that as a filler material this species of shells may be used in the fabrication of brake pads for road vehicles.
