Part of the Sagamore Army Materials Research Conference Proceedings book series (SAMC, volume 14)


Electron paramagnetic resonance was used to study the free radicals formed during mechanical fracture and γ-irradiation. The experimental results are reported herein. An identification of the free radicals is given and the rate of recombination and the rate of reaction with oxygen discussed. Preliminary tensile fracture data for drawn Nylon 6 fibers is also included.
