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, both woven and UD tape formats, can be used in hybrid laminates to enable your design whilst reducing cost, weight and environmental impact of your products..
