WASHINGTON, D.C., March 21, 2017 -- Polymers are used for myriad applications today, and perhaps the most important property that dictates which polymer is chosen for a given application is its "glass ...

THE variation of ultrasonic velocities with temperature in methyl methacrylate polymers was determined by Protzman 1 and by Melchor and Petrauskas 2. Using the optical diffraction method, Protzman ...

Polymer matrix composites (PMCs) exhibit impressive stiffness and strength properties that are commonly attributed to the reinforcing fibers. However, for many important mechanical properties, the ...

This series of articles is designed to help molders understand how a few analytical tools can help diagnose a part failure. Michael Sepe is our analyst and author. He is the technical director at ...

High-Q microcavities have provided increasing opportunities for optical sensing and precision measurement in the past decades, with intriguing features of miniature size, non-invasiveness and fast ...

Thermoplastics are processed in the molten state, their final shape and internal structure are established by cooling, and they can be softened and reshaped by reapplication of heat and pressure. Also ...

This article focuses on the application of thermogravimetric analysis (TGA), thermomechanical analysis (TMA), and dynamic mechanical analysis (DMA) techniques. It comprehensively discusses the various ...

In the race to lighter, safer, and more-efficient electronics — from electric vehicles (EVs) to energy grids — one component literally holds the power: The polymer capacitor. Seen in such applications ...
