With the drive for lighter weight, lower cost composite parts in a wide range of sectors and applications, Composites Evolution are working with companies to utilise the benefits of our natural fibre reinforcements when used in conjunction with carbon fibre.
Using Biotex Flax, in prepreg format, to replace a portion of carbon fibre layers in a laminate can
- Lower cost
- Reduce weight
- Increasing the vibration damping of the final component
- Maintain bending stiffness*
- Maintain impact properties**
|Laminate density (g/cm³)||1.5||1.3||1.4|
|Flexural modulus (GPa)||47||12||44|
|Flexural strength (MPa)||870||180||560|
|Damping loss factor||0.012||0.028||0.019|
In addition, the carbon/flax micro-sandwiches have recently been shown to perform very well in automotive sled impact tests. A 50/50 carbon/flax hybrid crush structure was found to have equal specific energy absorption to an all-carbon structure, whilst exhibiting a safer mode of failure.
Flax/Carbon Impact Test
With a similar Coefficient of Thermal Expansion (CTE), Biotex Flax can be considered for use in both components and tooling applications. All Biotex Flax grades can be used in hybrid laminates to enable your design whilst reducing cost, weight and environmental impact of your products.

As part of our recent research, Composites Evolution have driven several large-scale funded projects to gain a great understanding of the benefits of using flax fibres in conjunction with carbon fibre reinforcements.
