Abstract:

A model for the compressive buckling of an extended polymer chain is presented. The application of classical elastic-instability analysis to an idealized polymer chain reveals that the bending rigidity and critical buckling loads for a chain are proportional to the force constants for valence bond angle bending and torsion. Highly oriented polymer fibers are treated as a collection of elastic chains or columns that interact laterally. The critical stresses to buckle this collection of chains are calculated following a procedure developed to predict the compressive strengths of fiber reinforced composites.
