METHOD OF CO-DRAWING HYBRID INCOMPATIBLE MATERIALS

摘要

A method of drawing different materials includes forming a first material into a preform body defining at least one channel extending therethrough having a first cross-sectional area. A first element formed of a second material is inserted into the channel and with the preform body creates a preform assembly. The first element has a cross-sectional area that is less than the cross-sectional area of the channel, and the second material has a higher melting temperature than the first material. The preform assembly is heated so that the first material softens and the preform assembly is drawn so that the preform body deforms at a first deformation rate to a smaller cross-sectional area and the first element substantially maintains a constant cross-sectional area throughout the drawing process. Upon completion of the drawing step, the cross-sectional area of the channel is equivalent to the cross-sectional area of the first element.

1. A method of co-drawing different materials, comprising the steps of:
providing a preform body comprising one or more first materials, the preform body defining at least one channel extending therethrough, the channel having a first cross-sectional area; wherein an element formed of one or more second materials is inserted into and through the channel in the preform body and in combination with the preform body, creating a preform assembly; wherein the element has a cross-sectional area that is less than the cross-sectional area of the at least one channel, and further wherein the one or more second materials do not melt at melting temperatures for the first one or more materials; heating the preform assembly to a point where the one or more first materials soften; and drawing the preform assembly in such a manner that the preform body deforms to define a smaller cross-sectional area of said at least one channel and the cross sectional area of the element does not change as much as the cross sectional area of the one or more first materials does throughout the drawing process.
