Improved Data Acquisition Using A Novel Dynamic Mechanical Analysis Sample Preparation Technique: The Numbers Do Not Lie, Jordan J. Winetrout May 2019

Improved Data Acquisition Using A Novel Dynamic Mechanical Analysis Sample Preparation Technique: The Numbers Do Not Lie, Jordan J. Winetrout

Honors Theses

Dynamic mechanical analysis (DMA) is a technique commonly used to identify the thermomechanical properties of polymeric materials. In the aerospace industry, a typical DMA sample is a glassy epoxy-amine polymer network. On a laboratory scale, these types of materials are cured in a silicon mold and sanded by hand to yield a sample with testable dimensions. This preparation technique is time consuming and causes sample imperfections which negatively affects data acquisition. This thesis aims to absolve the issues with DMA sample preparation by using a custom vacuum housing and a DeWALTTM brand orbital sander. This novel approach has been …

Design Process Of A Novel Dynamic Mechanical Analysis Sample Preparation Methodology, Julian M. Richardson

Honors Theses

The technique of dynamic mechanical analysis (DMA) has been a frontrunner in the field of polymer science for decades. It’s used as a tool for characterization has been integral in mankind’s understanding of the properties of polymeric materials. The procedure for obtaining data using DMA is widespread and standardized, however the procedure for preparing the samples is a list of dimensions and tolerances with no mention of how to obtain said dimensions. Every research group using DMA is left to their own devices to prepare samples. This discontinuity can create the problem of nonuniform results across the scientific community. This …
