PRE IMPREGNATED FIBERS

​

Our prepreg production process offers with 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. 

​

• less weight than classic GRP (20-30%)

• less waste (<2%)

• almost zero production errors

• no harmful styrene or VOC emissions

• no human contact to chemicals

• no chemical mixing and vapour exposure

​

Our 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.

FIRE PROOFED

​

Notus prepregs are 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.

Fire resistance is a particularly important factor. In the past, composite materials have often been unable to comply with regulations, but we capable to create solutions to fit into the standards.

​

- special coatings (intumescent paint)

- coatings with Gypsum plaster, GPC, UHPC or ceramic tiles

- fire retardant resins and foams

- fire protection (rockwool, metal)

- construction methods

For Example:

In the UK the Building (Amendment) Regulations 2018 states that building work shall be carried out so that material which become part of an external wall are of European Classification “A2-s1, d0” or “A1”.

These classifications are taken from BS EN 13501-1:2007+A1:2009.  The Building (Amendment) Regulations 2018, came into force on 21st December 2018 and will apply to all projects, as described above, that started on site after 21st February 2019.

​

In the Middle East, NFPA 285 is a standard for fire testing. We can design, produce and test panels and parts that meet the testing standards.
