Flax fiber composite fabric ampliTex® 5040

braid

Product description Bidirectional fabric with fibers oriented at 0° and 90°, suitable for manufacturing fiber reinforced composite products with a high performance and a low environmental impact. ampliTex® 5040 has a very good drapability and is ideal for complex shapes. High laminate stiffness is obtained due to the low crimp twill 2/2 weave as well as zero-twist yarns. Performance advantage Considering that glass fibers have a density of 2600 kg/m 3 and a tensile modulus of 70 GPa, the flax ampliTex® 0°/90° 300 gsm can replace a 495 gsm glass fiber 0°/90° fabric to have the same stiffness in tension. In compression, the performance of flax is a bit lower, thus the flax ampliTex® 0°/90° 300 gsm can replace a 410 gsm glass fiber 0°/90° fabric to have the same stiffness. This fabric is ideal to be combined with the powerRibs fabrics 5019 and 5020, replacing a 600 gsm carbon fiberlayer with same performances in bending. 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.
