CARBON FIBRE COMPOSITE MATERIALS IN MECHANICAL STRUCTURES
Original language description
This paper described new hybrid composites products based on combination of winding technology with 3D cellular structure and dynamic damping layers. Multiscale homogenization on a micro scale and on a mezzo scale and final FE analysis on the hybrid material composite structure leads to satisfactory design of complicated machine parts. Analytical methods can be conveniently and effective used in the first step of the design phase and for the optimization process. Experimental investigation, as well as numerical simulations, showed that 3D cell composite structure can be more effective in transferring a shearing force than a classical unidirectional or layered structure. Application of damping layers significantly contributes to the rate of vibration decay and dynamic damping. With using of hybrid composites, parts of high stiffness and very good shear and normal strength can be designed. It was demonstrated on the prototype of the carbon/epoxy spindle for CNC machine centre.
