flax for composites

Material for a low carbon future

Flax has exceptional ecological properties. That is why this natural European fibre is found more and more on the innovative industrial markets. The industrial sector today must after all consider the sustainable development of their production methods.

The excellent mechanical properties of flax fibres can compete more and more with other synthetic fibres in the composite world.

Flax fibres are green by nature. But as a 100% renewable raw material, these sustainable fibres are also perfectly recyclable, biodegradable and compostable. Furthermore, they are at the same time exceptionally strong yet very lightweight. Flax fibre is characterised by high rigidity and vibration absorption and low density (1.4 p (g/cm³)) compared to glass fibre (2.54 p (g/cm³)) and other composite fibres. As thermal and acoustic isolator, it offers many ecological benefits and its impact on the environment is limited. Its low abrasion is also a strength not to be denied.

The best mechanical properties in composites are achieved by using full uni-directional layers. So it's not by applying yarns, fabrics or flax rovings. The mechanical properties of the uni-directional layers are high because of the absence of twist and shrinkage. A cross-ply laminate of UD layers of flax and a PP matrix offers rigidity of more than 10 GPa in a fibre volume fraction of 35%. In a composite, this has a strength of 130 MPa and a density of 1.05 g/cm³. (source JEC Composites). Precisely because of its many years hackling experience, Procotex is able today to offer a UD flax prepreg which is quite regular in weight and fibre per m².

Procotex can offer UD flax prepregs for both the Thermoplast and Thermoset market. In cooperation with the customer, by-products can also be offered such as UD flax fibres in the form of a flat strip (raffia), (spread tow fabrics)…
