Aluminium Paddle Roller (longitudinal grooves)
Robust aluminium deaeration roller with pronounced longitudinal grooves for glass fibre wet laminates.
For effective deaeration, compaction and consolidation of glass fibre mats, glass fabrics and glass non-crimp fabrics during hand lay-up. The profiled roller supports even resin distribution and helps work trapped air reliably out of the laminate.
The R&G aluminium deaeration roller with longitudinal grooves is a proven laminating tool for processing fibre-reinforced wet laminates. Especially with glass fibre reinforcements, the rigid profiled aluminium roller allows intensive and controlled processing of the wet laminate.
The pronounced longitudinal grooves transfer pressure directly into the reinforcement. As the roller passes over the laminate, the fibre layers and resin are pressed against the mould surface while trapped air between the fibres and individual laminate layers is worked towards the surface.
The roller is particularly suitable for glass fibre mats as well as medium and heavy glass fabrics and non-crimp fabrics. Its rigid aluminium construction also allows effective compaction of thicker laminate build-ups.
With a working width of 70 mm, the roller provides a good balance between surface coverage and controlled handling. It is particularly suitable for flat and slightly curved surfaces as well as medium-sized components. For tight internal radii, corners or narrow recesses, dedicated edge or radius rollers are more suitable.
Typical applications:
- Deaerating glass fibre wet laminates
- Compacting glass fibre mats
- Processing medium and heavy glass fabrics
- Processing glass non-crimp fabrics
- Pressing reinforcement evenly against the mould surface
- Distributing laminating resin throughout the reinforcement
- Hand laminating in mould and composite component production
Dimensions:
- Working width: 70 mm
- Roller diameter: 21 mm
- Overall length: 26 cm
Roller material: Aluminium
When is this roller particularly useful?
The longitudinally grooved aluminium roller is especially suitable for glass fibre laminates where intensive deaeration and compaction are required. The 70 mm wide roller is easy to control while still providing good surface coverage for medium-sized and larger laminating work.
Note on carbon fabrics:
When working with sensitive carbon fabrics, profiled aluminium rollers should only be used with light pressure. The pronounced grooves can disturb fibre orientation or distort the weave pattern if excessive pressure is applied. For high-quality visible carbon laminates, less aggressive roller profiles are often the better choice.
