Nida-Fusion STO Complex

Used for production of planar sandwich structures, Nida-Fusion STO complex is made of :

• Rigid foam core with closed cells to prevent resin absorption,
• Fibres reinforcement on each side of the foam,
• Fiberglass roving, which goes through them obliquely, forming triangulations Truss Network.

AVAILABLE CONFIGURATIONS

Rigid foams:

These foams have an excellent insulation factor: between 0.018 and 0.023 W/m°K

Polyurethane foams (PU)

These are the most commonly used on the market..

Size :

• Length : from 1.5 to 3.2 meters, according to customers needs
• Width : 1.25 meter
• Thickness : 10 to 65 mm, according to customers needs

Polyisocyanurate foams (PI)

With the same dimensions as the polyurethane foam, they have a good fire resistance :

• Standard NF 92501 : M1
• Standard DIN 4102 : B2
• Standard ISO 3582 ou BS 4735 : max.mm 10
  Brankkennziffer : 5.3

Nida-Fusion STO Complex before and after impregnation with cavity partial of foam.

Phenolic foams (PH)

This kind of foam has a very high fire resistance without any toxic fumes.

• Standard NF 92501 : M1, (F : under approval)
• Standard DIN 4102 : B2
• Standard iso 3582 or BS 4735 : max mm 10

This type of foam is easily damaged and must be handled with care before impregnation.

Size :

• Length : 1.00 meter
• Width : 1.25 meter
• Thickness : from 20 to 65 mm, according to customers needs

Reinforcements :

All the reinforcements available on the market can be used (fibreglass, aramid, carbon) :

• Woven fabrics,
• Non woven fabrics,
• Complexes.

The Nida-Fusion STO complex is produced with only one layer of reinforcement on each side.

Triangulations :

The triangulations of the sandwich material are characterised by :

The Spacing

The spacing corresponds to the distance between two stitches that have the same orientation. It can vary from 10 to 60 mm.

More the spacing of triangulations will be small, better will be the mechanical properties. However, this core will be heavier.

The Orientation

Two possibilities :

Parallel Orientation

All the stitching lines are parallel to the length of the sheet.
Flexural strength is good in the length side of the sheet.

Off Axis orientation

All the stitching lines are oriented with a 30 degrees angle to the length of the sheet.
This configuration gives good bending resistance across the width of the core as well as along the length.
