| Description
| - In this paper, two different woven reinforcements (twill 2x2 and plain 1x1) are determined by experimental observation to define their geometrical parameters. Geometrical parameters such as yarn density, type of weaving crimp in weft and warp direction, yarn density in each direction and yarn width in each direction, are measured on real microphotographs of metalurgical cross-section. Real microfhotographs were scanned by using method composed image on metallurgical microscope Nikon Eclipse ME 600 D conected with CCD camera DS-5M, they further were processed by the tools of Image proccesing tollbox in MATLAB® and NIS-elements®. It is necessary to use a special type of scanning based on the idea „every internal structural element reflects light in other way. Experimental observation, based on geometrical approach, seems to have more advantages, and to be more realistic. The multi-scale acces in the set of fabrics (macro-scale), composed of yarns (meso-scale), yarns themselves composed of fibers (micro-scale), leads to mechanical or electrical behavior. It is possible to define the textile geometry of such meso-mechanical models and to define an elementary woven cell. As a conclusion, the observations of real composite structure is not easy, however, it is a very important point of view. Reorganization of the yarns and fabrics during composite manufacturing seems to be a very important phenomenon for mechanical behaviour.
