A New Composite Material Based on Dry Impregnation

26 February 2007

Fibroline has patented its innovative dry impregnation process as a new concept for obtaining a composite reinforced with extra-long fibres, trademarked as FibroComp.

The innovative properties of the manufacturing process for FibroComp have just been rewarded by the JEC Innovation Programme 2007, which selected it as one of the finalists in the category “Process”.

The process uses powdered thermoplastic or thermoset resins to impregnate chopped rovings. Based on the application of an alternating electrical field, the dry impregnation process can be used to impregnate porous structures (such as non-woven material, fabric, foam, paper) with all types of powdered materials. Different types of powders with different levels of conductivity can be used, providing a flexibility that allows a wide range of applications and fibre-reinforcement/matrix combinations.

“The process we have developed allows the fibrous structure to be fully impregnated, guaranteeing perfect homogeneity. The flexibility of the process, which is just as suitable for mass production as for small series, offers a customisable solution that can meet very specific requirements,” said Laurence Caramaro, the head of R&D at Fibroline.

Fibroline says that the process also helps to reduce production costs, thanks to the use of inexpensive raw materials, low energy consumption and no solvents.
