Bio-based aerospace composites – step 1

The project ran between November 2020 and July 2021.

New variants of bio-based benzoxazines were developed for lower melting points and to enable filling of fabrics and molds in composite production. A unimolecular resin based on naringenine benzoxazine (NarBz) has been prepared. The availability of a unimolecular resin system is expected to have the effect of making it easier to correlate molecular structure with properties which can facilitate material development. Achieved results show that bio-based benzoxaziner are promising as future aerospace composites.
