Coefficient of Thermal Expansion: A Crucial Material Property

NETZSCH Kunststoffe TMA CTE

The design of parts and components made of fiber-reinforced composites needs to take the coefficient of thermal expansion into account because it determines the extent to which a material changes its dimensions when heated or cooled. Thermomechanical Analysis is the perfect method to predict product performance and processing behavior. Read our contribution to the journal Kunststoffe International for an overview of applications.

Der Wärmeausdehnungskoeffizient: Eine entscheidende Materialeigenschaft

NETZSCH Kunststoffe TMA CTE

Bei der Konstruktion von Bauteilen und Komponenten aus Faserverbundwerkstoffen muss der Wärmeausdehnungskoeffizient berücksichtigt werden, denn er bestimmt, wie stark sich ein Material bei Erwärmung oder Abkühlung in seinen Dimensionen verändert. Thermomechanische Analyse (TMA) ist die perfekte Methode für die Vorhersage der Produktleistung und des Verarbeitungsverhaltens. Lesen Sie unseren Beitrag in der Zeitschrift Kunststoffe!

What TMA Measurements Can Tell About Filler Orientation in Injection Molding

Fillers have long played an important role in the polymer manufacturing industry. An important property to measure how the filled material changes in length when being heated or cooled is the coefficient of thermal expansion. Knowledge about this material behavior is required to be able to determine important design values. Learn how the flow field and sample preparation influences the property and see how measurements with the TMA 402 F3 Hyperion® Polymer Edition are carried out.

Quality Control of Electronic Assemblies Using Thermomechanical Analysis

TMA Polymer Edition Electronic Assemblies1

A major source of failure of electronic assemblies is thermal expansion and the problems it causes. To make sure that the circuit base boards conform to a certain quality, IPC standards were put into place that require measurement of the thermal expansion, glass transition and softening point. Learn how you can comply to the standard with the new TMA 402 F3 Hyperion® Polymer Edition.
