Carbon fiber reinforced composites (CFRCs) are a kind of most
potential materials due to high strength-to-weight ratio, excellent fatigue and
corrosion resistance. However, the vast majority of CFRCs prepared from
carbon fiber and thermosetting matrices are difficult to be recycled and depend
on limited fossil resources. Here, for the first time, we reported fully bio-based catalyst-free epoxy vitrimers for
CFRCs. The epoxy vitrimers exhibited excellent
malleability and could be reprocessed by compression molding. Outstanding
degradability was also achieved, which enabled multiple recovery of CF without
damage from their CFRCs. In addition, CFRCs regenerated from multiple
recovered CFs exhibited insignificant differences from the original CFRCs. This
work will provide an effective method for the sound development of CFRCs from
both economic and environmental aspects.
