“…Likewise, the weight content of CFRPs in Boeing 787 Dreamliner and Airbus A350 has reached over 50% [ 9 ]. For modern high-performance CFRPs, epoxy resins are the most widely utilized thermosetting matrix due to their superior mechanical performance, dimensional stability, adhesion, and heat and chemical resistance [ 10 , 11 , 12 , 13 ]. Different from aerospace applications, the successful implementation of CFRPs in automotive mass production requires a much higher rate of production and throughput, which sets a significantly shorter time limit for the part cure cycle.…”

Imidazole cured epoxy resin systems were evaluated for one-component, fast-curing resins for liquid molding of automotive composite parts according to industry requirements. It was demonstrated that an epoxy resin-1-(cyanoethyl)-2-ethyl-4-methylimidazol(EP-1C2E4MIM) system would cure in a few minutes at 120 °C, while exhibiting acceptable pot life, viscosity profiles, and low water absorption. Moreover, this system yielded high Tg parts with mechanical properties similar to the amine-epoxy systems, which are the mainstream two-component epoxy resin systems for automobiles.

“…Therefore, epoxy is needed to mix with the curing agent just before use. Several types of one-component epoxy systems were reported, , which did not need to be mixed before use. The microcapsule system, in which the microcapsules including the curing agent are dispersed into epoxide in advance, is one of the attractive methods for preparing a one-component epoxy adhesive system.…”

Preparation of Microcapsules Containing a Curing Agent for Epoxy Resin by Polyaddition Reaction with the Self-Assembly of Phase-Separated Polymer Method in an Aqueous Dispersed System

To prepare cured epoxy resin particles encapsulating a curing agent (diamine), the self-assembly of phase-separated polymer (SaPSeP) method was developed to be applicable to polyaddition reaction of a stoichiometrically imbalanced system. The SaPSeP method was developed by the authors for preparation of micrometer-sized, hollow cross-linked polymer particles by radical polymerization based on the self-assembly of phase-separated polymer at the inner interface of particles. Although a polyaddition reaction, in general, requires that the reactants are in stoichiometric balance for the cure reaction to proceed well, diamine was successfully encapsulated within a cured epoxy resin shell by utilizing the SaPSeP method regardless of stoichiometric imbalance. The results provide further support of the previously proposed SaPSeP mechanism for the formation of hollow particles. Moreover, such diamine capsules can be employed in one-component epoxy adhesives.

“…Its reaction with an amine released from the imine results in the formation of a thiol group able to catalyse the amine-epoxide reaction. From the viewpoint of the adhesive properties, they report that the addition of methacrylate copolymer results in an improvement of the adhesive strength [188].…”

Recent advances in macromolecular chemistry have revolutionized the way we perceive the synthesis of polymers. Polymerization, to be modern, must be "controlled", which usually means capable of producing macromolecules of well-defined structure. The purpose of this review is to examine how the chemistry of epoxy resins, an almost century-old chemistry, is also involved in this movement. Epoxy resins are characterized by both the flexibility of implementation and the qualities of the polymers obtained. Key materials in health-, mobility-and energy related technologies, these resins are heavily present in high-performance composites, electronic boards, adhesives and coatings. Currently, a large number of resins and hardeners are available on the market or described in the literature and an interesting point is that almost any combination of the two is possible. Common to all these recipes and processes is that a liquid (or soluble) resin at some point becomes insoluble and solid. It is very important to know how to manage this transition, physically known as the gel point, as it is the point after which the shape of the object is irreversibly set. Taking into account the variety of epoxy polymerization processespolyaddition, anionic or cationic polymerization-we detail a number of methods to program the occurrence of the gel point and how this type of control affects the structure of the growing network.
