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.- Features

Applications & Uses
- Applications
- Compatible Polymers & Resins
- Composites Processing Methods
- Processing guidelines
- Great compatibility with epoxy and polyester
- Near zero CTE
- Compatible with infusion based processes (vacuum infusion, RTM), wet layup, bladder inflation molding (BIM) and compression molding
- 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)
- Fiber weight fraction of 50% can be reached with process pressure > 5 bars. However, the fibers 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.
