Aluminium V-Roller (Bubble Buster)
Robust aluminium deaeration roller with longitudinal grooves and V-notches for glass fibre wet laminates.
The profiled roller surface effectively works trapped air out of the laminate and supports uniform impregnation and compaction – particularly with glass fibre mats and heavier glass fabrics.
The R&G aluminium deaeration roller with longitudinal grooves and V-notches is a versatile laminating tool for processing glass fibre reinforcements in hand lay-up applications. With a working width of 100 mm, it is particularly suitable for medium-sized and larger surfaces.
The combination of pronounced longitudinal grooves and V-shaped notches provides intensive action on the wet laminate. As the roller moves across the surface, trapped air bubbles are mobilised and worked towards the surface. At the same time, the reinforcement is pressed against the mould contour and the laminating resin is distributed throughout the fibre layers.
The V-notches interrupt the continuous longitudinal grooves and reduce the tendency for resin to splash sideways when the roller is moved quickly. This allows controlled and clean operation over the laminate.
The aluminium roller is particularly well suited for glass fibre mats as well as medium to heavy glass fabrics and non-crimp fabrics. Its rigid metal construction allows effective compaction even with thicker laminate build-ups.
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
- Hand laminating in mould and composite component production

Roller material: Aluminium
When is this roller particularly useful?
The relatively wide and strongly profiled aluminium roller is a good choice for larger glass fibre laminates and thicker reinforcement layers where trapped air needs to be removed reliably. For small radii and tight contours, narrower deaeration rollers are more suitable.
