“…The significant improvement in EP mechanical properties by the addition of two different modifiers was already confirmed and reported in the literature. 32,33 Tensile adhesive strength (TAS) and shear adhesive strength (SAS) of EP are presented in Table 2 as a function of nanoclay (Nanobent ZW1) and reactive rubber (ATBN) content. Addition of either modifier improved the adhesive strength of the polymer matrix.…”

The present work investigates the effect of organomodified nanoclay (ZW1) and butadiene-acrylonitrile copolymer terminated with amine group (ATBN copolymer) on the properties of epoxy resin (EP). The impact strength (IS) and the critical stress intensity factor (K C ) values of EP containing 1% nanoclay increased approximately by 200% and 75%, respectively, in relation to neat EP. Moreover, hybrid composites containing 1% or 2% nanoclay and ATBN showed improved mechanical properties in relation with unmodified EP. The magnification and analysis of the Fourier-transform infrared spectra showed an increase in the peak height of 3338 cm -1 due to polymeric modifier incorporation. This finding might be explained by the reaction between modifier or hardener amine groups and the unreacted part of EP cured at room temperature. Hybrid composite containing 2% Nanobent ZW1 and 5% ATBN exhibited synergistic effect in terms of tensile adhesive strength toward composites with one modifier. Moreover, scanning electron micrographs showed more elongated and leaf-like structure for hybrid compositions, explaining the enhancement of IS and K C values of the tested composites.

“…Recently, studies have focused on novel approaches to toughen epoxy thermosets. For instance, interpenetrating networks 21,22 and hyperbranched polymer 23,24 can not only toughen epoxy resin but also improve modulus without sacricing T g which has attracted the attention of researchers. However, prohibitive costs and complicated preparation limit the applications of these strategies.…”

“…The value of impact performance was 76.6 kJ/m 2 , which is better than the 9.25 kJ/m 2 in Park’s study and the 17.63 kJ/m 2 in Hai-an Xie’s study [34,35]. Compared with that reported in other people’s research, the performance of the pressure resistance is greatly improved [36]. The results are in agreement with those shown in Figure 2.…”

In this paper, a novel modified epoxy resin with an interpenetrating network structure for use as a grouting material with high toughness was prepared by a method of graft copolymerization between polyurethane prepolymer (PUP) trimer and epoxy resin (E-44). Polyurethane prepolymer was synthesized using poly(propylene glycol) (PPG) and 2,4-toluene diisocyanate trimer (TDIT) at 70 °C for 3 h. The graft copolymer was prepared by grafting polyurethane prepolymer onto the side chain of epoxy resin at 110 °C. The mechanical properties, fracture surface morphology, chemical structure, thermal properties, and corrosion resistance of the modified epoxy resin curing products were studied. Due to the beneficial flexible segments and the interpenetrating network structure, the results show that when the ratio of epoxy resin to polyurethane prepolymer is 10:2, the optimum mechanical properties are obtained; these include a compressive resistance of 184.8 MPa, impact property of 76.6 kJ/m2, and elongation at break of 31.5%. At the same time, the modified epoxy resin curing product also has excellent heat and corrosion resistance. This work provides a new method for the study of epoxy resins with high performance.
