CARBON FIBER TUBES
Textechno, a German manufacturer of testing equipment for textiles, and the Leibniz Institute for Polymer Research Dresden, have won the JEC World Innovation Award 2016 for a new testing system which can access the properties of a fiber to matrix interface.
The quality of a composite laminate, especially the stiffness, can be dependent on a good adhesion strength between the reinforcing fiber and the polymer matrix. To accurately and reliably measure the bonding between fibers and resins, Textechno developed Fimatest, the first system that is commercially available consisting of two devices Fimabond, a partially automated embedding station suitable for all fibers and resins systems, and the pullout tester Favimat+, which can also be used for single filament linear density and tensile testing.
"The FIMATEST system is a new building block for testing the quality of composite laminates with glass or carbon fiber reinforcement," said Dr Ulrich Mörschel, CEO of Textechno. "This development was possible through an excellent collaboration with the well known expert Professor Edith Mäder from the Dresden Leibniz Institute for Polymer Research who contributed the knowledge of the micromechanical behaviour."
"The composite market is continuously growing and requires world-class testing systems measuring the quality of the products," said Dr Michael Effing, CEO of AMAC GmbH and advisor for Composite Materials to Textechno. "The fiber matrix interface is a key feature for mechanical performance. I am very pleased that Textechno has developed this system in a very short time frame and can already present it at the JEC."
The first system has been delivered to the new Fraunhofer ICT Institute in Augsburg, Germany and another unit has been sold to a glass fiber producer in the USA, the company says.
