Interlaminar fracture toughness behaviour of carbon fibre reinforced polymer with epoxy-dicarboxylic acid vitrimer matrix

Self-healable fiber-reinforced vitrimer composites: overview and future prospects

“…In a very recent study, Gresil and co-workers have studies the instability of the crack propagation for vitrimer/CFRP composites. 72 The authors observed that laminates within the vitrimer matrix acquired a higher load than pure epoxy CFRP to propagate the crack, especially when interface adhesion between vitrimer matrix and the carbon fiber is strong. While considering the energy at crack propagation, fracture toughness for fibers/vitrimer was increased by ∼63%, with respect to epoxy/CF, confirming that apart from toughness of the matrix, interface and the interphase between matrix and the fibre play a very important role on fracture toughness.…”

Vitrimer composites: current status and future challenges

“…Furthermore, SEM micrographs of fracture surfaces after double cantilever beam test showed matrix residues onto the carbon fibres indicating a satisfying interfacial adhesion. 56 Considering the societal invectives towards bio-based resins, the use and development of such matrices in combination with vitrimers also attracted considerable attention. 57 Based on renewable resources, Wang et al prepared a CFRP composite comprised of a Schiff base epoxy matrix with a high T g of 172°C and good mechanical properties.…”

Preparation and Properties of Polysaccharide‐Based Epoxy Vitrimers

“…[1,2] The curing agents are of great importance to the properties of the cured epoxy resins. Common curing agents include amines, [3][4][5] acid anhydrides, [6][7][8][9][10] polyphenols, [11][12][13] polythiols, [14][15][16][17] and other modified curing agents. [18] Although there are currently various kinds of curing agents on the market, which can make the cured epoxy resin meet various market demands.…”
