“…This is attributed that the presence of graphene in the epoxy enables conductive paths (as seen in Figure 3 and Figure 7B) between the carbon plies, [ 18 ] and help carrying electrons through the matrix‐CF networks by reducing the surface resistance of the epoxy matrix. [ 28 ] Because the epoxy matrix used in the present study is an aeronautical grade and dielectric in nature, increasing its conductivity as in the present study could improve its ability to dissipate electric charge due to the lightning strike. [ 29 ] The measured T–T–T conductivity of 1.25 GNP sample (239 × 10 −3 S/m) is comparable to that reported by Kandare et al [ 15 ] as 170 × 10 −3 S/m for a 1 vol% GNP epoxy/CF composite.…”

In this study, graphene nanoplatelets (GNPs) added to epoxy matrix composite reinforced by aeronautical grade carbon fibers (CFs) were fabricated by the vacuum infusion method, and the effect of different GNPs contents (0.05, 0.25, and 1.25 wt%) on electrical conductivity, flexural properties, and dynamic mechanical properties were investigated. The results revealed an 8-and 73-times improvement in conductivity values across the thickness with the addition of 0.05 and 0.25 wt% GNPs, respectively, compared to the neat composite. Flexural test results showed that with the addition of 0.05 GNP, only 6% increase in flexural strength was obtained, while with the addition of 0.25 wt% GNP flexural strength remained almost the same as for the neat composite. On the contrary, the addition of GNPs (1.25% by weight) causes a reduction in the flexural strength with respect to the neat composite. This was confirmed by the fractured surfaces examined by scanning electron microscope which reveals that considerable amount of fiber-matrix debonding was observed with 1.25 GNPs loading. Dynamic mechanical analysis (DMA) revealed that the storage modulus of the neat composite increased by 12.6% with the addition of only a small amount of GNP (0.05% wt) compared to the neat composite. Composite with 1.25 GNP shows upward bending, affecting the shape of the cole-cole plot obtained from DMA results, indicating inappropriate interactions of GNPs in both the matrix and CF in the composite.

This review aims to review the biomedical applications of nanocarbons to various cardiovascular devices including implantable scaffolds, patches, and stents against coronary artery diseases (CAD). The clinical applications of nanocarbons in cardiac tissue engineering, cardiomyocyte supporting implants, biosensors for cardiovascular biomarkers, bioimaging and monitoring of pathological conditions of CAD are addressed. In addition, the current challenges in minimizing the toxicity of nanocarbon materials and alleviating techniques are discussed from a clinical perspective. A novel fabrication approach for nanocarbons in cell-laden cardiovascular stents is a promising regenerative means for the treatment of damaged infarction in CAD.

“…[2][3][4][5] One of the most important methods to improve the lowspeed impact resistance is the interlayer toughening technology. [6][7][8][9][10][11][12][13][14][15][16][17][18][19] Usually, this technology inserts high toughness or high strength interleaves into the interlayer of laminates. The interleaves play the roles in crack bridging, deflection and viscoelastic energy dissipation, thus they effectively improve the areal energy dissipation density during crack propagation, resulting in the improvement of fracture toughness.…”

“…16 On the other hand, improving the surface conductivity and the conductivity through thickness direction (σ z ) is important for the lightning-strike protection of CFRPs. [17][18][19] A higher σ z and more conductive paths in the matrix are even more important for a composite without surface protection, which can effectively disperse the lightning current through more highly conductive carbon fibers. 20 The common methods for improving the conductivity include adding conductive particles into the resin matrix [21][22][23] and introducing conductive materials into the interlayers.…”

A composite laminate with high conductivity and high mode I fracture toughness was prepared by using a silver-plated nylon mesh as the interleaf. Through in-depth comparison with the silver-plated non-woven veil interleaved composites, the mechanisms of the conductivity improvement and interlaminar toughening were discussed. The conductivities along the fiber direction, in transverse to fiber direction and through thickness direction reached 739 S/cm, 734 S/cm, and 5.4 S/cm, respectively, which increased by 196%, 344,500%, and 4326%, respectively, and are much higher than these of the other modified systems. At the same time, the mode I interlaminar fracture toughness increased by 112%. Mechanism study shows that the conductivities along the fiber direction and in transverse to fiber direction are greatly affected by the interleaf conductivity, while the conductivity through thickness direction is little affected. The toughening mechanism of the plain or silver-plated nylon mesh is much different from that of the non-woven veils. Both of the composites interleaved with the plain or silver-plated nylon mesh have higher mode I interlaminar fracture toughness, but less improved mode II toughness. The effect of silver-plating on the mode I and mode II fracture toughness was studied.
