Zwick USA will host a free webinar to discuss some of the key considerations engineers should evaluate when testing long fiber reinforced composites.
The event takes place on Thursday, 30 July at 10 am Eastern Time and will be presented by Helmut Fahrenholz, plastics and composites industry manager for Zwick/Roell. It will offer an overview of different tools and fixtures for composites testing, methods of strain measurement and typical differences in the international testing standards.
Demand for long fiber reinforced composites with polymeric matrices continues to increase as engineers seek specialized materials with mechanical properties that can be tuned to support the requirements of a structural part. Fiber reinforced composites consist of long, thin fibers that are either directionally or randomly oriented. It is the fiber orientation in composites that makes measuring their properties disproportionately more complex than for other materials, such as metals and plastics, according to Fahrenholz. Testing of composite materials is also complicated by the broad array of standards and test procedures in use. There are currently more than 150 standards – some more than 30 years old – that describe the physical testing of fiber-reinforced composites, he said.
Static materials testing is required to generate sufficient data for material qualification and for optimization of elements and sub-structures; however, the multitude of methods available through organizations such as ASTM, ISO and EN, as well as specifications set by aerospace industry manufacturers, can be difficult to navigate. As selection of the testing standard plays a vital role in robust material qualification, this informational seminar from Zwick USA offers information to support decision-making on protocols for static testing of fiber-reinforced composites.
