Flax 2×2 Twill – Amplitex – 200gsm

BComp AmpliTex™ 2×2 twill is an environmentally friendly and sustainable alternative to traditional composite reinforcements such as glass fibre. As well as its environmental credentials, flax fibre has an attractive natural aesthetic and excellent vibration damping properties. It is suitable for most laminating processes including hand-layup, vacuum bagging and resin infusion.

The flax fibres used in ampliTex™ fabrics have a modulus of about 60 GPa and a tensile strength of 800 MPa, which makes them a performing technical fibre. Comparing the specific stiffness of ampliTex™ and glass fibres shows that the tensile performance of ampliTex™ fabrics is about 50% better. Further advantages are vibration damping properties which are much greater compared to glass or carbon fibre, and less fragile fracture behaviour than carbon fibre.

Key performance advantages:

• Very high specific stiffness and strength
• Architecture optimized for composite processing and performance
• Reliable and highly consistent performance across batches
• Viscoelastic behaviour providing very efficient vibration damping
• Excellent inherent compatibility with thermosets via covalent bonding
• Very low CTE, hence high thermoelastic compatibility with carbon fibres
• Highly radio-transparent accross the entire RF spectrum (1 – 40 GHz) even in thick laminates
• Long fatigue life in cyclic loading
• Compatible with vacuum infusion, wet layupm RTM, BIM, autoclave processes and compression moulding
• CO2 sequestrator: the emissions related to process energy from the flax seed to the ampliTex™ roll are offset by the sequestration at growth via photosynthesis (1.65 kg of CO2 sequestrated / kg fibre) ampliTex™ coupled with Bcomp powerRibs™ patented surface reinforcement can produce a full natural fibre laminate that matches the flexural rigidity of a monolithic CFRP laminate of the same weight.

This woven cloth is 1m wide and sold by the linear metre.
