Fiber Length Analysis

FILDAS® - Test systems for fibre distribution analyses

Important properties of injection moulded or extruded fibre composite plastic components are influenced by the effective length of the embedded fibres. The determination of the fibre length after the end of the process has therefore been part of the quality assurance of FRP processors as well as in the R&D sector for several years. However, previously available test methods were often very time-consuming and associated with certain limitations in terms of accuracy and practicality.

Many years of practical experience in the fields of systems engineering, digital image processing and physical-chemical laboratory analysis have gone into the Fildas instrument series. The powerful FiLDAS systems use an automated sequence of image acquisition, pattern recognition, classification and data analysis with report generation in Excel format.

The systems, which are available with dark-field and/or bright-field illumination, allow analyses of glass fibres, aramid fibres, natural fibres or carbon fibres, depending on the configuration.

Features / Equipment:

• Depending on the type of unit and the task, various analysis procedures with different degrees of automation are available
• Fully automated analysis, optimised for short (or straight) fibres
• Analysis of samples with ultra-long and/or crossed fibres / clusters
• Image acquisition using special scanner or DigiMic systems
• Test report, automatically generated (diagrams and data listings in Excel format)
