“…27 A reduction in curing temperature can reduce the energy consumption and cost of manufacturing adhesively bonded structural parts, 28,29 especially when the structural parts are large. 30 Seraji et al 31 utilized 2-ethyl-4-methylimidazole (2E4MI) and boron trifluoride ethylamine (BF 3 ) to accelerate the curing of flame-retardant-modified epoxy amine resin systems. They found that both 2E4MI and BF 3 accelerated the onset of curing and that increasing the flame retardant content in the modified epoxy resin reduced the glass transition temperature.…”

Accelerating the curing of epoxy/aromatic amine adhesives and improving their toughness are challenges in heat-resistant epoxy structural adhesives. Herein, we report an epoxy/aromatic amine adhesive accelerated curing system with an oxo-centered trinuclear (chromium III) complex, which is toughened using a thermoplastic block copolymer (TPBC). The reaction characteristics, heat resistance, microstructure, and bonding properties of the accelerated epoxy adhesives were analyzed. The reaction peak temperature of the epoxy with 3% catalyst was 113.1 C, which was 113.6 C lower than that of epoxy without catalyst, and the modified epoxy resin demonstrated a potential for rapid curing at medium temperature. The glass transition temperature of the TPBC-toughened epoxy adhesive was 125 C after curing, indicating excellent thermal stability after medium temperature curing. The introduction of the TPBC increased the single-lap shear strength of the epoxy adhesive without reducing its heat resistance. The shear strength at room temperature and 120 C of the modified epoxy adhesive with 50 phr of TPBC was 25.2 and 10.9 MPa, respectively. Moreover, the epoxy film adhesive exhibited outstanding bonding properties when used in the bonding of lightweight honeycomb sandwich structures.

Adhesively bonded cutting tools possess many advantages over classic (insert) tools due to different manufacturing processes: With reduced manufacturing temperatures, the damage to the cutting edge decreases, and the damping effects of the adhesive enhance the tool’s life. In contrast to standard joining technologies like soldering, adhesive bonding enables the joining of various cutting materials and tool base bodies, like ceramic and steel. Furthermore, the usage of expensive, abrasive-resisted cutting materials, like carbide, has to be reduced in future because of the classification of the components (cobalt, wolfram carbide) as a critical resource. Therefore, this article conducts a feasibility study of adhesively bonded drills with a ceramic tip for cutting carbon-fiber-reinforced plastics. The main contents are investigations of different surface preparation methods (laser surface texturing and SACO-blasting), examining four different adhesives for cutting tool usage, and manufacturing and validating prototype drills for cutting operations. The experimental results show a high scattering of the toughness of the joints between 2.8 MPa and 27.8 MPa, depending on the combination of surface preparation and adhesives. Also, the choice of adhesive influences the performance of the manufactured drills. The maximum number of drilled holes scatters between 15 and 67 holes before breakage. A linear relation within the analysis of axial forces and factors of the covered area is observed. For further studies, the surface preparation needs to be improved, the glass transition temperature must be maximized, and the drill geometry must be optimized. Furthermore, a cooling concept for the cutting tools needs to be investigated.
