This is a dry lab due to hazardous nature of the experiment. The students only have to plot the data given in the handout and discuss them. Objective Lecture Lab work Data Reduction Handout Acrylic Miscellaneous Data Reduction Figure 1.3 Failure load vs. exposure time load-environment combination of Nylon 66 fiber. See Miscellaneous for comments on the graph. Materials are continually changing, both on a molecular and macroscopic scale.
Macroscopic changes can occur as a result of energy input to the material system.
This can result in morphological changes that can drastically alter material behavior. To help us become more familiar with materials other than metals, a general overview of polymer morphology will be discussed in the lecture. The experiment will be explained in the lecture and if opportunity arises an experiment in progress will be shown. This experiment investigates the effect of different environments on Nylon 66 fibers. Actual data obtained from the Nylon 66 degradation studies are provided for use in the report write-up.
