PRE IMPREGNATED FIBERS
The new NOTUS NE7 prepreg system was developed by our sister company NOTUS Composites, also based in the UAE. The novel low-temperature curing chemistry offers significant cost advantages and allowed us to switch from the infusion lamination process without developing expensive new high-temperature tooling.
The overall production cost is similar to or even lower than vacuum infusion due to cost savings in the shop during application and cleaning, less waste and lower health and safety costs. We are using the system for all AEOLOS yachts and the AEOLOS Flying Dutchman.
NE7 prepregs can be cured at temperatures as low as 70˚C, with the standard cure cycle being 12 hours at 70˚C, matching the typical cycle time for an infused part with a component Tg of 85˚C. NE7 materials have a good outlife of 30 days at 20˚C and are available with unidirectional, multiaxial and woven reinforcements. NE7 can also be supplied as a resin film.
Notus Composites is also well known for the outstanding fire performance of its’ specialist epoxy FR prepregs. The company’s EPFR-609 FR prepreg materials (tested and certified to NFPA 285, ASTM E84 and EN13501-1) are now available with the NE7 low temperature curing technology, combining additional processing options with market leading fire performance.
THE BEAUTY OF FABRIC
Composite materials have their own beauty. In recent years we have gained unsurpassed experience in applying great looking fabrics even to complex surfaces. These surfaces turn a carbon part into an iconic object.
Fabrics applied on 20cm width curved objects
Each material has its own characteristics. The fibres are embedded in the matrix. The stiffness can be drastically increased with light "spacer" materials.
- carbon fiber (CFK)
- glass fiber (GRP)
- aramide fibers: Kevlar and Twaron (AFK)
- polyethylene fibers (Dyneema)
- polyester fibers
- basalt fibers
- ceramic fibers
- boron fibers
- natural fibers
The king of the fibers
Unidirectional carbon fibre is a real asset: because the fibre can be placed exactly in the direction of force, it offers enormous potential for increasing strength and durability while reducing weight. In addition, unidirectional fibre is again much stronger (typically twice as strong) than woven fibre because the tensile potential is much higher at only a fraction of the weight density. In woven materials the fibre makes curves, which means that it is more flexible. UD fibre does not bend when subjected to force - it lies flat. Flexibility is as important as strength. In unidirectional fibres, you can overlap them at different angles and orientations to maximise strength in different areas while keeping the fabric stiff and stable.
If aesthetics are an important part of the design, unidirectional fibres allow you to overlap the fabric with a variety of carbon fabrics to create a dynamic new look that is pleasing to the eye.
