Abstract
Malleable crosslinked polymers represent a new class of materials, wherein reversible covalent bonds are employed. These materials can exhibit mechanical properties of typical thermosets under ambient conditions, yet at elevated temperatures or under other stimuli they can be reprocessed and recycled like thermoplastics through a cross-link exchange and rearrangement process, usually with the aid of catalysts. This presentation will focus on the development of a light-weight composite material consisting of a catalyst-free thermoset matrix and low-density nanofillers or carbon fibers (CFs). The resulting composites become malleable upon thermal activation, thus enabling its unique reprocessability, rehealability, and full recyclability while retaining good mechanical properties.
