Summary: A new kind of reprocessable shape memory thermosetting resins (DBE) is developed with enhanced heat resistance and mechanical strength by constructing a crosslinked network based on N,N' -4,4' -diphenylmethane bismaleimide, bisphenol A epoxy resin and 4,4' -dithiodiphenylamine. The DBE resins exhibit multiple phase structures, and 1DBE shows the best integrated performance with high T-g, tensile strength, good reprocessability, and excellent shape memory performance.

Summary: The study focuses on composite fabrication, characterization, and recyclability of biobased polymer resins reinforced with flax fiber. By selecting different biobased resins and evaluating their mechanical properties, an epoxy resin cured with a cleavable hardener is found to have the highest glass transition temperature, ensuring full recyclability. The study also demonstrates the possibility of separating and recovering fibers and resin from composite panels through a specific chemical process.

Summary: This study demonstrates the enhancement of epoxy resin by incorporating soft butyl glycidyl ether (BGE) and rigid nano-silica (nano-SiO2) in a controlled manner. The synergy between the self-assembly effect of BGE and the well-dispersed nano-SiO2 results in improved mechanical properties and processing performance compared to the Pure EP system. The low viscosity of the toughening systems provides superior processing performance for large-scale production of composites in automotive manufacturing.
