Composites Evolution (Chesterfield / UK; www.compositesevolution.com) has launched a range of polyfurfuryl alcohol (PFA) thermosetting bioresin prepegs for composite applications. PFA is derived from hemicellulose crop waste such as sugarcane bagasse, and is similar in nature to phenolic resins.

Brendon Weager, managing director at Composites Evolution, says: “Customers can now specify bioresin composite components that have mechanical properties, fire performance and cost – all equivalent to existing oil-derived composites.”

The PFA bioresin prepegs are based on aligned fabrics such as woven glass and flax, as well as other fibre types including carbon. They can be consolidated by vacuum, autoclave or press and are designed for applications in mass transport, aerospace, furniture and construction, among others. The flax/PFA prepregs are made from Composites Evolution’s “Biotex Flax” fabrics and are therefore 100% bio-derived, the company notes.
