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

Proceedings of 56th Dornbirn-MFC (2017)

Textechno has a focus on the development of instruments for the characterization of the physical properties of reinforcement fibers, rovings and the fibre-matrix adhesion. We discuss in detail the measurement of the fibre-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).

To Characterise the drapeability of reinforcement fabrics, is one of the most sought after abilities of those designing composite processes and components. Получить больше информаций…

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.
