Flax Fibres

  • 1.  Flax Fibres

    Posted 03-07-2018 12:25

    I am interested in linking up with anybody who is involved with the use of natural fibres such as flax in commercial / industrial composites. My specific area of interest is concerned with the structural attributes of flax fibres and how this may impact upon their use in composites
    I look forward to feed back from fellow SAMPE Members

    Best Wishes

    Hi Patrick,

    I encourage you to contact Sunstrand LLC as they are working with flax in this area.  Likewise, we are working on the physical testing of natural fibers, including flax, in my lab for industrial use.  The problem is not an easy one, but I would happy to talk with you directly if you like.

    I made a saddle using natural fiber composites while exploring these materials at CCA. Flax is an interesting starting point, although silk and hemp are likely to provide a better strength-to-weight ratio. Haven't seen any testing, though. Would love to know more about this project

    Patrick: At some point the flax fiber that is developed by your team for commercial applications has to be incorporated into a thermoplastic or thermoset polymer of Portland cement composition.


    At the Nano-interface where the flax and polymer (or any dissimilar material meet), the flax and polymer must be bonded atomically in order to maintain long term aging properties and overcome any of the normal deficiencies that occur with any material.


    My Mission is to teach the more efficient use of raw materials such as flax using 1.5-nanometer organometallic titanates and zirconates.


    Summary:  We can couple the flax to a polymer with titanates and just like silanes couple fiberglass. 


    When you have a specific program to develop a product and process – I can supply you with a titanate in a product form with application details.

    I have a question, do basalt fibers fall into the category of natural fibers?

  • 6.  RE: Flax Fibres

    Posted 03-09-2018 15:09
    No, basalt fiber is made from "basalt" which is rock material. It is not a "natural fiber" like hemp, flax, jute, etc.

    Basalt is not a natural fibre, but is made from natural volcanic material without significant reformulation, i.e. just melting and spinning.
    Conversely, bamboo can be a natural fibre, but much of what is on the market as "bamboo fibre" is reconstituted cellulose, rather than raw unprocessed fibre where the solvents used may not be environmentally friendly!

    We do not use, manufacture or sell natural fibers for composites but we do sell polypropylene fiber for use with natural fibers in composites. If I can be of assistance please contact me.

    Hi Patrick,

    I am the North American representative for Dia-Stron. 

    Dia-Stron's history may be rooted in hair fibre metrology, but our mission has always been to drive innovation in line with our customers' ever changing requirements. A customer enquiry in early 2000 led Dia-Stron to begin trialling tensile and dimensional measurements of carbon fibres on our existing hair testing instrumentation, resulting in the development of the range of technical fibre testing instruments that we offer today.

    These instruments have evolved specifically for measuring challenging technical fibre samples; starting with the inception of the LEX Linear Extensometer - a tensile measurement system with the high level of precision and sensitivity required for measuring carbon or glass filaments.
    The FDAS770 utilises a high-frequency Laser Scanning Micrometer for accurate, non-contact dimensional measurement of fibres with fully automated fibre rotation and translation. Fibre cross-sectional area can be calculated for the conversion of force to stress data. The FDAS770 lends itself to irregular, opaque or semi-transparent fibres, and our sample mounting techniques can support a wide variety of specimens, such as cotton, glass, flax, bamboo and silk.  A Dynamic Swelling Module (DSM770) can be incorporated for swelling and wet diameter measurements.

    Our equipment has been successfully applied to the measurement of natural fibers, which is where we meet your interests.
    Please visit out website or reach out to me at for further information.

    Kind Regards
    Joe Flitcroft

    Impressive that you test human fibers (hair) in addition to graphite fibers.
