With a wealth of expertise in natural fibres and especially in flax fibre, Groupe DEHONDT® launches an innovative range in composite reinforcement : FLAX TECHNIC

FLAX TECHNIC exploits the intrinsic mechanical properties of long flax fibres and fills a slot in the market next to glass and carbon reinforcement, opening prospects along the path toward eco-composites.

Groupe DEHONDT® is present at all stages of the technological transformation of raw materials for the flax industry :

Design, manufacture and marketing of materials and industrial equipment

Marketing of flax fibre reinforcement and semi-products

More than 8 % of its turnover is spent on R&D.

FLAX TECHNIC consists of 3 types of reinforcement : NATTEX ®, TWINFLAX®, LINTEX®, which are implemented according to their application : automobile, aeronautics, rail, marine, sport & leisure, construction, etc.

FLAX TECHNIC represents a large range of natural flax fibres issued from a specific culture, different from flax fibres for the textile industry. All of these products incorporate a complete quality approach that englobes : Traceability of raw materials from the seed to growing conditions, harvesting and

processing Qualified products meeting specific standards (ISO and NF XP T 25-501) for technical flax

fibre Experience of over 10 years in the use of bio-based reinforcement in composite

materials working in collaboration with industry players and recognized composite laboratories

NATCUT Cutter

The NATCUT cutting device can adjust a spray-up system to use continuous natural fibers. After several years of development, NATCUT can now be installed on robotic or semi-automatic equipment in place of chopper guns for spray-up. When used with NATTEX® Roving, the implementation of composite parts by spray up is now possible.

NATCUT, designed for spray up.

Specifications Fed with 2 or 4 bobbins of 3000 Tex Discharge rate between 2 and 10 kg/min Dimensions of NATCUT (without robot)

o Height 530 mm o Width 255 mm o Length 350 mm

Electrical power < 1 kW Weight 5 - 15 kg depending on model On-site setting up study on request
