Flax fiber composite fabric 5051

braid

Product description Flax fibre braid, suitable for manufacturing fibre reinforced composite tubes with high performance and low environmental impact. Performance advantage Considering that glass fibers have a density of 2600 kg/m3 and a tensile modulus of 70 GPa, the flax ampliTex® braid can replace a 50.8 g/m glass fiber braid Processing guidelines • Great compatibility with epoxy and polyester • Near zero CTE, hence good processing compatibility with carbon fibres • Compatible with infusion based processes (vacuum infusion, RTM), wet layup, bladder inflation moulding (BIM) and compression moulding • Flax fibres always contain some humidity at ambient conditions. Some resins (especially polyesters) are sensitive to moisture and may badly polymerize or create bubbles. In that case, dry the fabrics before use (110°C for 15 minutes) • Fibre weight fraction of 50% can be reached with process pressure > 5 bars. However, the fibres absorb a lot of resin when hand-laminating the fabric and it tends to look “dry” (unless too much resin is used) before pressure is applied. We recommend controlling the amount of adhesive used for laminating and impregnating it with 50 to 60% resin in weight. Excess resin comes out while pressing the fabric.
