Composite solid of high performance for applications in optical fibre technology and high performance polishing.

摘要

Composite solid of high performance for applications in the technology of optical fibres and polishing of high performance. Invention patent for a composite solid prepared based on a mixture of liquid epoxy epotek 301 - 2 32 or the like with a combination of zirconia and oxides of cerium and amorphous silica.The proportion of the mixture need not be exact and may vary slightly according to a material more or less harsh, more or less plastic, or more or less thermally stable. However, a proportion efficient is obtained with the following concentration: for every 100 grams of epoxy are added 15 grams of oxide, zirconia, 6 grams of oxide of cerium and 2 grams of amorphous silica.The compound is prepared in a porcelain crucible and mixed with porcelain pestle to obtain a mixture viscous and homogenous white colour which is placed in a vacuum chamber 10 ^ - 3 ^ Torr for about 120 minutes for removing micro bubbles which is left after the To dry by the time of curing of epoxy.The solid material thus obtained is then aged with heating and cooling 60 C 198 0 C 198 5 times or more, thereby producing a composite hard but easy to work around and cutter and self abrasive characteristics.In accordance with the characteristics physico chemical analysis presented in the basic experimental composite concerned is a materiaj self abrasive, has a coefficient of thermal expansion significantly lower than that of pure epoxy hardened.With these characteristics can, therefore, be applied in the manufacturing technology of optical fiber connectors, mono or multi fibre scaffolds of ends of optical fibres, polishing wheels, high performance surfaces of silica or optical glass and in the manufacture of CO High precision mechanical mponentes operating in gradients of temperature between - 20 and 40 degrees.
