The lightweight veils can be interleaved between reinforcement plies to improve the interlaminar toughness of a composite structure.
The lightweight veils can be interleaved between reinforcement plies to improve the interlaminar toughness of a composite structure.

The veils are designed to improve the mechanical properties in composites and will be on show at JEC Europe in March.

‘The lightweight veils can be interleaved between reinforcement plies to provide a means to significantly improve the interlaminar toughness of a composite structure, increasing resistance to both mode-I and mode-II fracture,’ said business development director Adam Black.

Resin flow

As well as the new range of thermoplastic veils TFP will be showcasing an array of products from its Optiveil, Optimat and Tecnofire ranges. The Optiveil and Optimat ranges enable a high quality surface finish whilst simultaneously imparting surface functionality such as conductivity, EMI shielding and corrosion and abrasion resistance to a composite structure. They can also be used as a resin flow medium, providing improved resin transportation in both interlaminar and surface regions and removing the need to use additional flow media. 

The ultra lightweight veils, from 2 g/m², are an effective carrier or support for adhesive films, ensuring a minimum weight addition whilst improving handling and setting the bond line.
