“…Recently, it has been shown that the hybrid combination of CNTs and graphene materials can be used to improve the mechanical and electrical properties of FRPs. 28–31 The mixture of 1D (CNTs) and 2D (graphene) nanomaterials can result in hybrid forms (3D structures) with synergetic effects on properties. Although various research works have demonstrated the effectiveness of carbon nanofillers either individually or in combination on the improvement of some mechanical properties of FRPs, the effect of using a hybrid combination of CNTs and graphene materials, specifically for the GIC and GIIC has not completely addressed.…”

This work reports the influence of seawater ageing on the mode I and mode II interlaminar fracture toughness ([Formula: see text] and [Formula: see text]) of prepreg-based unidirectional carbon fiber/epoxy laminates containing carbon nanofillers. Double cantilever beam and end notched flexure specimens were fabricated from composite laminates containing multiwalled carbon nanotubes and/or reduced graphene oxide at their middle plane interface. Experimental results showed that the addition of carbon nanofillers moderately increased the [Formula: see text] and [Formula: see text] propagation of composite laminates before and after their immersion in seawater with respect to the reference laminate under dry condition. For double cantilever beam and end notched flexure specimens aged in seawater, it was observed that [Formula: see text] and [Formula: see text] increased by 57% and 13% for specimens with multiwalled carbon nanotube/reduced graphene oxide hybrid combination, 39% and 4% for specimens with multiwalled carbon nanotubes and 53% and 8% for specimens with reduced graphene oxide respectively, as a consequence of the plasticization effect of seawater immersion on the matrix. Fracture surface examination by scanning electron microscopy revealed interlaminar failure associated to mode I and mode II delamination and toughening mechanisms produced by the multiwalled carbon nanotubes and reduced graphene oxide at delaminated regions of composite laminates.

“…SEM was used to observe the fracture surface of the specimen in order to clarify the above mode II interlaminar fracture results of the composite laminates 71 . Figure 7 presented the SEM images of fracture cross‐section morphology of composite laminates under the action of different concentrations of modified BN solution.…”

At present, the application of epoxy resin and its composites was severely restricted by its disadvantages of intrinsic brittleness after curing, poor fatigue strength, and low fracture energy. In order to improve its mechanical performances and broaden its applied range, the modified boron nitride‐basalt fiber/epoxy resin composite laminates (EP‐BF/mBN) were successfully prepared via a hot‐press process by using BF as reinforcement of epoxy resin composites and BN nanosheets treated by codeposition of PDA and PEI as toughening agent. The effects of the concentration of modified BN solution on the mechanical properties of the composites were studied in terms of flexural strength, flexural modulus, the interlaminar shear strength (ILSS), and the mode II interlaminar fracture toughness (GIIC). When 6 g L−1 modified BN solution was added, the flexural strength, flexural modulus, ILSS, and GIIC increased by 12.7%, 10.4%, 37.0%, 62.3%, respectively. And flexural strength, flexural modulus, ILSS, and GIIC approached to 894.6 MPa, 34.6 GPa, 60.4 MPa, and 483.9 J m−2, respectively, which was 20.0%, 10.7%, 38.9%, and 68.9% higher than that of EP‐BF at −60°C, suggesting that EP‐BF/mBN even had better mechanical performances at low temperature, which would be widely used in more fields in the future.

“…Contact angles were measured using a DSA100 instrument (Krüss, Germany). The dispersive components, polar components and total surface energy can be calculated according to Eqns :

γ = γ^{normald} + γ^{normalp}, γ_{normals} = γ_{normals}^{normald} + γ_{normals}^{normalp}, γ_{normall} = γ_{normall}^{normald} + γ_{normall}^{normalp}

γ_{normall} (1 + \cos θ) = 2 {((), γ_{l}^{d} γ_{s}^{d})}^{1 / 2} + 2 {((), γ_{l}^{p} γ_{s}^{p})}^{1 / 2}

where γ l ( γ s ), γ l d ( γ s d ) and γ l p ( γ s p ) are surface tension, dispersive and polar components of the test liquid (sample), respectively. In the present study, the test liquids were deionized water ( γ d = 21.8 mN m −1 , γ = 72.8 mN m −1 ) and glycerol ( γ d = 34.0 mN m −1 , γ = 64.0 mN m −1 ).…”

The incorporation of hyperbranched polyamide-functionalized graphene oxide (HPA-GO) into epoxy was proposed to improve the interfacial and mechanical properties. Benefiting from improved dispersion and strengthened interfacial interaction, epoxy composites with HPA-GO showed significant improvements in mechanical and thermomechanical properties at low GO loading. The interaction at the HPA-GO/epoxy interface was investigated to confirm the occurrence of chemical bonding. Strong interfacial bonding improved the stress transfer and distribution of HPA-GO/epoxy interface. Accordingly, the overall strength of epoxy composites was effectively improved on account of the uniform dispersion of HPA-GO and interfacial chemical interaction between HPA-GO and epoxy. Compared with neat epoxy resin, the inclusion of 0.10 wt% HPA-GO led to 310.5 and 37.2% increase in impact strength and tensile strength, respectively.
