The standardization of the micromechanical single-fibre pull-out test is urgently requested by the industry. The corresponding DIN SPEC 19289 “Fibre-reinforced Composites – Measurement of Interfacial Shear Strength by means of a Micromechanical Single-Fibre Pull-Out Test” was recently published within the scope of the publicly funded WIPANO project “WiPull”, which was conducted between the partners Fraunhofer IGCV, Faserinstitut Bremen and Textechno. This project also included testing of the most relevant thermoplastic matrices like PA6, PP, PEEK and PC in combination with carbon fibres, recycled carbon fibres, glass, and natural fibres. This paper includes key findings of the WiPull project including the impact of tempering, ageing, degradation, and temperature profiles on the measured fibre-matrix adhesion strength. Furthermore, results of the round robin trials are shown and discussed.

Investigation of interfacial strength parameters in polymer matrix composites: Compatibility and reproducibility

Effects of various geometrical and physical factors, as well as the method of data reduction (analysis of experimental force–displacement curves) on the values of local interfacial strength parameters (local IFSS, τd, and critical energy release rate, Gic) determined by means of a single fiber pull-out test are discussed.

FIMATEST – A New Testing System to Determine the Fibre-Matrix Adhesion Strength by Means of Pull-Out Tests

Textechno has a focus on the development of instruments for the characterization of the physical properties of reinforcement fibers, rovings and the fiber-matrix adhesion. We discuss in detail the measurement of the fiber-matrix adhesion strength by means of the FIMATEST system which has been developed together two research institutes, the Leibniz-Institut für Polymerforschung (IPF) in Dresden and the Faserinstitut Bremen (FIBRE).

FIMATEST – Qualitätsmessung an Verbundwerkstoffen

JEC Composites Magazine No. 102, 2016, 49-51

Die Glas- und Carbonfaserindustrie setzt ihr schnelles Wachstum fort und erschließt immer neue Anwendungsgebiete. Eine Schlüsselgröße für hochqualitative Verbundwerkstoffe ist die Stärke der Haftung zwischen Faser und Matrix. Dieser Artikel beschreibt verschiedene Methoden und messtechnische Lösungen mit deren Hilfe ein hohes Niveau der Faser-Matrix Haftung erreicht und sichergestellt werden kann.


DIN SPEC 8100 – Neuer Standard für die Composite-Branche

Die DIN SPEC 8100 „Textilien – Verstärkungstextilien – Automatische Prüfung der Drapierbarkeit an Gelegen und Geweben für endlosfaserverstärkte Werkstoffe“ wurde durch Textechno in Zusammenarbeit mit dem DIN sowie SAERTEX, dem Faserinstitut Bremen (FIBRE), der Groz-Beckert KG und der FTA Albstadt erstellt.

New European Standard for Crimp- and Shrinkage Tests

The new European standard EN 14621 partially replaces the German standards DIN 53840 and DIN 53866, and contains crimp contraction- and shrinkage tests on multifilament yarns. Measurements according to the new standard can be automated by means of the automatic crimp- and shrinkage tester TEXTURMAT ME.

The tester has already been in use for measurements according to the DIN standards as well as to ASTM D 4031 (crimp properties) and ASTM D 2259 (shrinkage). A special software for testing air-textured yarns enlarges the scope of application of this tester.

Testing of Carbon Fibers

Testing of carbon fibers with FAVIMAT+ and ROBOT 2

The importance of carbon fibers as a reinforcement material in energy-saving lightweight composites is well accepted. Fast and reliable, i.e. automated, linear-density- and tensile testing of carbon fibers thus becomes increasingly important. Due to the special properties of carbon fibers an automatic handling of individual filaments has been considered to be problematic. TEXTECHNO in Mönchengladbach realizes an automated test of linear-density- and tensile properties on such carbon filaments in their automatic fiber test system FAVIMAT+ with ROBOT 2.

Automatic linear-density and tensile testing on carbon fibers

Automatic single-fiber linear-density and tensile tests on up to 500 individual carbon fibers are possible with the FAVIMAT-ROBOT 2 and FAVIMAT-AIROBOT 2 of Textechno. These carbon fiber testing techniques are described in this article.
