Flax fiber composite fabric 5027

unidirectional

Product description ampliTex flax-carbon fusion UD tape, non-crimp, 52 mm width, 225 gsm. Performance advantage The fusion tape brings the best of two worlds: the very high stiffness of carbon and the light weight and damping of flax. Both fibers also have a very good compatibility, since they have similar thermal expansion coefficient and failure strain. Processing guidelines • Good compatibility with epoxy and polyester • Near-zero CTE, • Compatible with infusion‐ based processes (vacuum infusion, RTM), wet layup, bladder inflation moulding (BIM) and compression moulding • Flax fibers 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 65% can be reached with process pressure > 5 bars. However, the flax 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 resin used for laminating and impregnating with 45 to 55% resin in weight. Excess resin comes out while pressing the fabric.
