RELATIONSHIP OF MICROSTRUCTURE TO STRENGTH OF GLASS FIBERS)
Abstract
The microstructure in E-glass marbles used as feed stock in commercial fiber production, as well as in laboratory crucible melts and coarse fibers drawn from such melts has been investigated. In each case, electron micrographs showed a high degree of non-uniformity. Some portions of all samples from these sources were almost structureless after etching with dilute HF, while other areas on the same samples showed evidence of a two-phase structure. The two phase areas consisted typically of 150-300 A diameter discrete, quasi-spherical particles in a continuous matrix. It is suggested that the discrete second phase particles are silica-ruich with respect to the matrix glass because of their apparent greater resistance to attack by HF solutions. (Author)
