The expanding offer
With a twofold bonus of mechanical and
environment-friendly properties, European
flax and hemp semi-finished products cover
a broad range of applications for thermoplastic and thermoset composites. This broad
product range was developed by emulation
by the players in the European industry, and
substantiates the technological maturity
of flax and hemp reinforcements for all
composite processes. Thanks to first-rate
management of the raw-material resource
and of the conversion and production tools
within the European flax and hemp industry,
this product range is able to address both the
commodity and high-performance markets
for composite semi-products. About a dozen
major stakeholders work closely with user

manufacturers to develop a European range
of flax and hemp semi-finished products in
the form of preforms, either dry (nonwoven
mats, technical textile roving) or preimpregnated (compound, tapes, UDs). These
fibres are not being used merely as a substitute for other synthetic fibres - they enable a
high number of industrial optimizations, yet
without obliging users to make changes to
their manufacturing processes.

Consolidated technical data
For reasons ranging from "green marketing"
to the availability of innovative high-performance products, the way flax and hemp
reinforced composites are perceived in the
European market has rapidly changed. With
the help of its European Scientific Committee, the CELC has supported the initiatives
of its industry for over a decade, through
methodical steps involving deliberation,
assessments and, especially, in-the-field
actions. Meeting industry needs at the international level requires being able to identify
performance according to standardized
criteria. The CELC Technical Section has
introduced harmonized datasheet templates
for flax and hemp preform producers.
Thanks to these guidelines, user manufacturers can be sure which flax and hemp
preforms fit their specifications according to
ISO standards.

Key application sectors

preforms, standardized ISO framework

The processability of flax and hemp
composites has enabled them to penetrate
the composites market. This includes the
sports and leisure segment, where vibration
damping is a key criterion, and the automotive segment, where optimizing the weight
of materials is always a goal. In segments
where the development process takes

Sports and leisure
The main added value of flax and hemp
reinforcements in the sports and leisure
sector is their vibration damping performance, providing more comfortable use
and higher precision for both amateur and
professional athletes. There are a number
of product families, including cycling,
sliding and racquet sports, and especially a
very broad range of international manufacturers that are now combining flax with
pragmatic innovation in the field. This is a
new market reality.
Automotive
One focus for the optimization of vehicle
energy consumption is lowering the weight
of the materials used, among other things.
Flax and hemp fibre reinforcements are
