Filament Winding Technology


Filament winding is a fabrication technique for manufacturing composite material. The process involves winding filaments over a male mould or mandrel. The most common filaments are carbon or glassfiber and are coated with synthetic resin as they are wound.Once the resin has cured, the mandrel is removed, leaving the hollow final product.Filament winding is well suited to automation, where the tension on the filaments can be carefully controlled. Filaments that are applied with high tension results in a final product with higher strength.Products currently being produced using this technique range from pipes, poles, pressure vessels and aeronautical and yacht elements. VEM uses various filament winding technologies, namely STEEL BAND TECH and LAM TECH for continuous winding and 2 to 5 axis machines for discontinuous winding.
