    1. An acid bath confirms the test sample is nylon.
    2. Fiber failure in the sample on the left was concentrated primarily in one area, while the outer fibers in the righthand sample failed along long stretches, indicating complete failure (as well as structural consistency).
    3. A close-up of this sample shows the fiber failure along the outer strands.
    4. Failure in this sample occurred at the start of the splice.
    5. Under a microscope, this sample’s fibers resemble those of a seed pod.
