Role of Fiber Finish in Wet Strength Retention of Glass Fibers

摘要

An experimental program was conducted to establish the role of the finish in the strength retention of E-glass fibers exposed to humid environments. The first phase was concerned with determining the basic strength of the dry fiber, the effects of moisture on the bare fiber, and the effectiveness of certain methods for removing moisture from the fiber surface. For this purpose, dry fibers were produced under highly controlled environmental conditions, thus obtaining reproducible strength. For comparison, fibers were also produced in a normal, humid atmosphere. This provided a basis for the second phase of the program which involved the evaluation of the effectiveness of a silane-epoxy finish in providing strength retention in the fiber. (Author)
