Thermal Diffusivity and Conductivity via Flash Method
Thermal Diffusivity and Conductivity via Flash Method PMIC recommends thermal diffusivity testing using the flash method for design applications, process control, quality assurance, and high sample throughput measurements. The flash method is invaluable as a relatively inexpensive, fast test method, usually requiring only a small amount of material for testing. PMIC introduced a TA…
Edge and End Effects of Low-Expansion Composites in Thermal Expansion Measurements
Edge and End Effects of Low-Expansion in Thermal Expansion Measurements Low-expansion graphite composites such as graphite face sheets, honeycomb panels, and similar materials have what PMIC refers to as edge and end effects, roughly depicted in Figure 1. These effects negatively influence length change measurement in Coefficient of Thermal Expansion (CTE) testing. For graphite…
Artemis Program and SPACECOM
Artemis Program and SPACECOM In November, Precision Measurements and Instruments Corporation attended SPACECOM in Houston, Texas. During this conference, numerous groups ranging from NASA to the Department of Energy discussed tactical matters impacting the commercial space industry. Part of the conference included NASA Theatre sessions where contacts from NASA discussed their upcoming missions, one of…
Composite Layup Check
Composite Layup Check As a testing laboratory, we have noticed that errors can occur with fiber layups, specifically when the layup of the material is not what it was intended to be. For example, we recently received material for Coefficient of Thermal Expansion Testing that was supposed to have a layup of 0-degree plies with…
CAMX 2019 Tradeshow Summary
CAMX 2019 Tradeshow Summary Precision Measurements and Instruments Corporation (PMIC) attended CAMX 2019 in Anaheim, CA this fall. The Exhibit Hall had a great turnout and we were able to talk to people from numerous industries, including a lot of our West Coast aerospace customers as well as an Asian company interested in measuring the…
