Connecting Molecular Exchange Dynamics to Stress Relaxation in Phase-Separated Dynamic Covalent Networks

January 22, 2024
Author(s)
Neil Dolinski, Ran Tao, Nicholas Boynton, Anthony Kotula, Charlie Lindberg, Kyle Petersen, Aaron M. Forster, Stuart Rowan
A suite of phase separated dynamic covalent networks based on highly tunable dynamic benzalcyanoacetate (BCA) thia-Michael acceptors are investigated. In situ kinetic studies on small molecule model systems are used in conjunction with macroscopic

Temperature-insensitive silicone composites as ballistic witness materials: the impact of water content on the thermophysical properties

July 28, 2021
Author(s)
Ran Tao, Fan Zhang, Huong Giang Nguyen, Philip Bernstein, Amanda L. Forster, Randy Mrozek, Aaron M. Forster
In this work, different formulations of a room-temperature silicone composite backing material (SCBM) composed of polydimethylsiloxane (PDMS), fumed silica and corn starch were investigated using different characterization techniques, i.e., differential

Calibration Procedures for Orthogonal Superposition Rheology

November 18, 2020
Author(s)
Ran Tao, Aaron M. Forster
Orthogonal superposition (OSP) rheology is an advanced rheological technique that involves superimposing a small-amplitude oscillatory shear deformation orthogonal to a primary shear flow. This technique allows the measurement of structural dynamics of

Multiscale polymer dynamics in hierarchical carbon nanotube reinforced glass fiber composites

June 5, 2019
Author(s)
Ajay Krishnamurthy, Ran Tao, Erkan Senses, Sagar Doshi, Erik Thostenson, Faraz Burni, Bharath Natarajan, Donald L. Hunston, Amanda L. Forster, Aaron M. Forster
Carbon-nanotube (CNT) grafted glass fiber reinforced epoxy nanocomposites (GFRP) present a hierarchy of stiffness (GPa to MPa) and lengths (µm to nm) scales at the fiber-matrix interphase. The contribution of interfacial CNT networks to the local and bulk

Rheology of ballistic clay: the effect of temperature and shear history

May 9, 2017
Author(s)
Ran Tao, Kirk D. Rice, Aaron M. Forster
Ballistic clay is used as a backing material for standards-based ballistic resistance tests for the purposes of providing a measure of the energy transferred to the body when a threat is defeated. However, this material exhibits complex thermomechanical
