Abstract:
A large number of cracking the conveyor belt, which occur during exploitation at stress level lower than the permitted, indicates a risk of damage and breakage. Therefore in designing it is necessary to define criteria by which one can achieve safety of exploitation conveyors with rubber belt from damage and breakage. In this analysis it is very important to treat the rubber conveyor belt as a classical composite material, which consists of a rubber as a matrix and a polyester- polyamide canvas as reinforcements. Rating of mechanical and exploitation properties, i.e. the emergence and development of damage in composite materials due to the static and dynamic loads is a complex phenomenon which consist: micro cracks in the rubber, a breakage of fiber of polyester-polyamide canvas, weakening of connection rubber-canvas and delamination. In this paper is presented the results of experimental studies of composite materials the rubber conveyor belt with cartridges made of polyester and polyamide. It is also presented the results of a new and exploited rubber conveyor belts in the direction of the load action, as follows: tensile strength, modulus of elasticity, Poisson's coefficient and strain.
