material and normally silica, their material properties are the same as the

materials listed in Table 24.1.

24.3 MECHANICAL PROPERTIES

In most of this section, we deal with general glass properties or with those of

silica fibers. In the final portions of the section, we review nonsilica fiber

properties.

In Table 24.1, columns five through eight, some data on the strengths of a

variety of glasses are given. In column 5, the highest reported measured strengths

are given, with the measurement temperature indicated in parenthesis. For silica

and the soda-lime–silica glass, these are strengths measured at 77 K for what are

thought to be flaw-free samples. The value for silica is the same as that for a

silica-clad light-guide fiber because in this case
