1. Phase (About Composite Materials)

THE TERM PHASE INDICATES A HOMOGENEOUS MATERIAL, SUCH AS A METAL OR CERAMIC IN WHICH ALL OF THE GRAINS HAVE THE SAME CRYSTAL STRUCTURE, OR A POLYMER WITH NO FILLERS. BY COMBINING THE PHASES, USING METHODS YET TO BE DESCRIBED, A NEW MATERIAL IS CREATED WITH AGGREGATE PERFORMANCE EXCEEDING THAT OF ITS PARTS. THE EFFECT IS SYNERGISTIC.

3. Synthetic Composites

SYNTHETIC COMPOSITES ARE MODERN MATERIAL SYSTEMS NORMALLY ASSOCIATED WITH THE MANUFACTURING INDUSTRIES, IN WHICH THE COMPONENTS ARE FIRST PRODUCED SEPARATELY AND THAN COMBINED IN A CONTROLLED WAY TO ACHIEVE THE DESIRED STRUCTURE, PROPERTIES, AND PART GEOMETRY. THESE SYNTHETIC MATERIALS ARE THE COMPOSITES NORMALLY THOUGHT OF IN THE CONTEXT OF ENGINEERED PRODUCTS.

5. Discontinuous Fibers (Whisker)

DISCONTINUOUS FIBERS (CHOPPED SECTION OF CONTINUOUS FIBERS) ARE SHORT LENGHTS (L/D = ROUGHLY 100). AN IMPORTANT TYPE OF DISCONTINUOUS FIBERS ARE WHISKER – HAIR- LIKE SINGLE CRYSTAL WITH DIAMETERS DOWN TO ABOUT 0,001 mm (0,00004 in) AND VERY HIGH STRENGHT.
