Characterization of Filamentwound Polymeric Composite Materials
Jovan Raduloviæ
The mechanical properties of a composite material - glass fiber/polyester resin, obtained by the filament winding technology, are presented in this paper. The filament winding technology produces cylindrical parts; since the methods of investigation of mechanical properties of composite materials define the usage of flat specimens, a new method of production of flat sheets by filament winding was developed first and then a procedure for obtaining defined specimens by machining flat sheets. The paper presents strength, elastic modulus and Poisson's ratio, obtained by the tension and compression parallel and perpendicular to the fibre direction, flexural strength, interlaminar strength, shear strength and shear modulus of mentioned filamentwound composite material.
Key words: composite materials, polymeric materials, filament winding technology, mechanical characteristics, polyester resin, glass fiber.
