FLAXPREG 110g Unidirectional Prepreg Flax Fibre (600mm)

This uncured prepreg is made using 110gsm unidirectional flax fibre with 50% RW epoxy matrix (resulting in an overall weight of 220gsm) and is laminated and cured in just the same was as a conventional glass or carbon fibre prepreg.

Like all ‘prepreg’ reinforcements supplied by Easy Composites, it is stored frozen (at -20°C) and shipped to customers straight from our freezers however the prepreg does have an outlife of 6-8 weeks at 23°C and so can travel safely on normal transport and does not necessarily need to be stored frozen on receipt.

For a UD reinforcement, FLAXPREG is surprisingly conformable and easy to laminate and is quite capable of conforming around tight and complex mould shapes and contours, as can be seen in the additional image of an S-Bend intake component, laminated using a FLAXPREG surface ply.

About Flax Fibre

Flax fibre is environmentally friendly and sustainable alternative to traditional composite reinforcements such as glass fibre.

Although flax fibre offers lower overall strength and stiffness compared to reinforcements such as glass fibre, it does offer particular advantages in vibration damping and sound absorption, along with adequate mechanical properties and a natural aesthetic to complement its environmental credentials.

How to Process

FLAXPREG can be cured at temperatures from 110°C (2hrs, resulting in a >113°C Tg) to 150°C (30mins, resulting in a >136°C Tg).

Although the prepreg is primarily designed for curing under positive pressure, such as in an autoclave or hot-press, good results can be achieved under vacuum pressure-only oven cure (out-of-autoclave) where the main compromise is likely to be some slight dryness of the surface texture.

See datasheet for full details on storage, handling and cure cycles.

Typical Uses

This UD flax prepreg can be used on its own (in multiple plies) or combined with other prepreg reinforcements (provide they have similar cure profiles and rheology). When used in combination with other reinforcements, FLAXPREG can be used to provide a natural appearance or to add vibration damping properties to glass or carbon prepreg laminates.

FLAXPREG is already being successfully used in volume production for automotive interior trim components.
