About this Dataset

Aged And Unaged Ultra High Molar Mass Polyethylene Flexible Unidirectional Composite Laminate Tensile Testing For Soft Body Armor Applications

This dataset contains mechanical testing data at two different loading rates for two different aging conditions (wet and dry at 70 °C) for five different extraction time points for ultra high molar mass polyethylene (UHMMPE) unidirectional (UD) laminate. In each folder there is a spreadsheet (.csv) with the test data collected during loading, and a (.avi) video file for each of the tests done under those conditions.
