RESEARCH USING COMPOSITE MATERIALS IN MANUFACTURING PRESSURERESISTANT CIRCULAR DETAILS WITH THE TWO SPHERICAL BOTTOM BY WINDING TECHNOLOGY

This paper presents the results of research about the using of composite materials to make circular rotating parts with two spherical ends. From the analysis of the working characteristics of this details, the article selected the winding technology and using composite materials to produce details with cylindrical and spherical shape characteristics. The material group that the article presents is a composite unidirectional glass fiber reinforced composite with polymer matrix. This material is characterized by a specific density of 2.02g/cm3; tensile strength is 1750MPa; elastic module is 55GPa; elongation reached 3.18%. With properties of such materials, it is suitable for working conditions of details.
