How does it work?
Advanced Composite Production Ensuring High Quality, Low Material Consumption, and Reduced Environmental Impact
Vacuum infusion is a technique within composite production used by SP Group, where vacuum is employed to draw liquid resin into a dry reinforcement pack. The process requires the reinforcement to be enclosed to achieve vacuum tightness. This can be ensured using a plastic film sealed with butyl rubber or a solid mould composed of multiple parts joined with gaskets. Typical materials include epoxy, polyester, and phenolic resins, as well as glass fibre or carbon fibre mats as reinforcement.
The technique can be applied to produce both large and small items, such as 120-metre-long wind turbine blades, boat hulls of various sizes, and diverse industrial products.
Advantages of Vacuum Infusion at SP Group:
Complete impregnation of the reinforcement pack ensures optimal laminate properties.
Closed process prevents the emission of environmentally harmful substances during production and curing.
Controlled resin usage in repeat mouldings ensures consistent results.
Minimal resin waste, reducing material consumption and costs.
Capability to produce items with complex geometric shapes.
