The Wetting Behavior of Fibers

  • Willard D. Bascom

Abstract

Historically, the technologies most interested in the wetting of fibers have been those involved in the processing of textiles.(1, 2) Much of the early scientific literature on wetting was concerned with liquid penetration into fabrics and other porous solids.(3) More recently, the rapid development of fiber reinforced composites, notably carbon fiber and glass fiber reinforced polymers (CFRP, GFRP), has generated a renewed interest in the wetting of fibers. However, in the interim there has been a change in the scientific attitude toward the use of contact angle measurements as a means of characterizing the surface chemical constitution of solids. In the early literature, the contact angle was viewed as a characteristic of the fiber and a parameter in the capillarity equations for liquid penetration. Due in large measure to the studies by W. A Zisman and co-workers, there has been a change in attitude toward the physical significance of contact angle measurements. It is now recognized that the contact angle can be a highly sensitive tool for surface characterization. Consequently, there is a growing body of literature on the wetting of textile fibers and fibers used in composites aimed at surface chemical characterization as well as the processing of these fibers into composite materials.
