title: Factors affecting low strength breaks: fractographic analysis.
abstract: This paper summarizes the results of a scanning electron microscopic study of several hundred low strength breaks. The low strength breaks were caused by several factors: particle damage to the fiber surface; abrasion of the fiber with a foreign surface; surface damage on the thin side of a poorly centered coating; and internal inclusions. Periodic statistics show that one or two causes predominate during any given period of time indicating certain out-of-control processing parameters. Overall particle damage and poorly centered coating were the two major causes of breaks at 345-MPa strength level.
