Abstract

Fracture in polymers is a complex phenomenon of considerable recent interest. Here we shall discuss an important subclass, i.e. highly-oriented polymer fibers. Several models have been proposed to describe the micro-structure in fibrous polymers. These range from the early fringed micelle structures (1) to more recently proposed folded chain models (2, 3). Although models proposed by Hearle (4); Bosley (5); Keller (6); Fischer et al. (7); Peterlin (2); Dismore and Statton (8); Gubanov and Chevychelov (9); Takayangai et al. (10); and Bonart and Hosemann (3) differ in some very important details, they have a basic common element in their microstructure; that is, they view polymers as alternating between highly-ordered regions and less ordered or “tie molecule” regions. For the particular melt spun, hot-drawn Nylon 6 fibers used in this research, Joon B. Park (11) has recently proposed a paracrystalline, folded chain structure as representative of the fiber microstructure.
