DESIGN AND APPLICATION OF COMPOSITE MATERIALS IN MECHANICAL STRUCTURES

Abstract

Design of machine structures with using composite parts allows to combine different sorts of material, manufacturing technology and thereby control stiffness, strength, dynamic response, weight, as well as the costs, and achieve the products “on request”. This paper describes new hybrid composites products based on combination of winding technology with 3D cellular structure and dynamic damping layers. An analytical methods and their effective use for optimization process and a multiscale homogenization on the micro and mezzo scale as well as the FE analysis of the final structure is described. Application of damping layers significantly contributes to the rate of vibration decay and dynamic damping.
