Abstract
AbstractA new kind of acetal fiber has been discovered which has a tensile strength of 1.7 GPa (250,000 psi) and an elastic modulus of 35 GPa (5 × 106psi). This fiber is produced by a special two‐stage drawing process in the solid state which requires careful control of deformation rate and temperature. Previously known drawn fibers are reported to consist of folded‐chain blocks joined by a limited number of tie‐molecules. It is hypothesized that the second stage of the novel drawing process eliminates the lamella (block) surfaces which act as strength‐limiting stress concentrators. A new type of fiber is created in which any remaining chain‐folds are distributed as defects in a continuous crystal matrix. It is the continuity of the crystal matrix which is believed responsible for the remarkable properties of the fiber.
