Fiber Length Analysis Testing Services

We analyze raw fibers, pellets, composite materials, finished components, and customer-supplied image data.

Fiber length is a critical factor influencing the mechanical properties of fiber-reinforced components.

Through our testing services, we support developers, quality managers, and material specialists in the reliable evaluation of plastic pellets, injection-molded parts, and finished components, including those used in the automotive industry.

As the developer of FASEP®, we are recognized worldwide for our software and measurement systems for fiber length analysis. Combining instrument development, software expertise, and many years of practical experience, we provide testing services at the highest professional and technical level.

We not only understand how to interpret measurement data, but also how fiber length analysis must be performed in the laboratory to deliver reliable and reproducible results.

Contact us if you need dependable information about the fiber length distribution of your plastic components. As the technology developer behind FASEP®, we provide expert support and results you can trust.

Wide Range of Sample Types

Our testing services are suitable for a broad range of materials and data sources. Depending on your application, we analyze:

  • Fiber-reinforced plastic pellets
  • Injection-molded parts and other plastic components
  • Raw fibers and fiber bundles
  • Composite materials and fiber-reinforced composites
  • Customer-supplied fiber images and microscopic images

Thanks to the flexibility of FASEP® technology, both physical samples and existing image data can be analyzed. This enables efficient support for development, quality assurance, and research projects without necessarily requiring the preparation of new samples.

Transparent Reporting​

Results are provided in a clear and structured Excel report, including:

  • Material data or component identification
  • Histogram of the fiber length distribution
  • All relevant characteristic values and key metrics
  • Complete data tables for further processing and documentation

Fast Support for Your Development Projects

Short turnaround times enable rapid evaluation of materials and components, providing development teams with the information they need for material selection, process optimization, and quality assessment.
