Unintended consequences: Assessing thermo-mechanical changes in vinyl nitrile foam due to micro-computed X-ray tomographic imaging

October 5, 2023
Author(s)
Alexander Landauer, Zois Tsinas, Orion Kafka, Newell Moser, Jack Leigh Glover, Aaron M. Forster
Micro-computed X-ray tomography (μCT) is a volumetric imaging tool used to quantify the internal structure of materials. μCT imaging with mechanical testing (in situ μCT) helps visualize strain-induced structural changes and develop structure-property

Effects of Thermal Aging on Molar Mass of Ultra-High Molar Mass Polyethylene Fibers

March 24, 2022
Author(s)
Zois Tsinas, Sara Orski, Viviana Bentley, Lorelis Gonzalez-Lopez, Mohamad Al-Sheikhly, Amanda L. Forster
Ultra-high molar mass polyethylene (UHMMPE) is commonly used for ballistic-resistant body armor applications due to the superior strength of the fibers fabricated from this material combined with its low density. However, polymeric materials are

Effects of temperature and humidity on high-strength p-aramid fibers used in body armor

Amy E. Engelbrecht-Wiggans, Faraz A. Burni, Emilien Guigues, Shefei Jiang, Vivian Yu, Thang Huynh, Zois Tsinas, Deborah Jacobs, Amanda L. Forster
To improve the reliability and design of body armor, it is imperative to understand the failure modes and the degradation rates of the materials used in armor. Despite the best efforts of manufacturers, some vulnerability of armor materials to aging due to

Protocols for Determining the Mechanical Properties of High Strength Copolymer Aramid Fibers

September 1, 2018
Author(s)
Amanda L. Forster, Viviana Rodriguez Cardenas, Ajay Krishnamurthy, Amy E. Engelbrecht-Wiggans, Zois Tsinas
The primary goal of the manuscript is to develop a protocol to prepare consistent specimens for accurate mechanical testing of high strength copolymer aramid fibers, by removing a coating and disentangling the individual fiber strands without introducing
