Abstract : The inter-relationships between conditions employed in processing E-glass prior to fiber production and the resulting microstructure of the glass and the strength of the fibers was the subject of the study. The intrinsic strength of fibers (defined as the tensile strength measured at -196C where stress corrosion mechanisms of failure are suppressed) appears to be particularly sensitive to variations in structure of the glass. On the other hand, strengths measured at room temperature, when stress corrosio can occur, do not parallel the changes measured in intrinsic strength. Considerable conflict in strength data obtained on glass fibers after presumably similar processing of the melt, and even between groups of fibers from the same melt, have been attributed to the unlikelihood of obtaining representative random samples from a non-homogeneous batch of glass by withdrawing a very small portion from one point as fibers.
