Graphene nanoplatelets are two-dimensional carbon structure materials with single or multilayers graphite plane which possesses attractive characteristics. In this study, the environmental aging effect on interlaminar properties of graphene nanoplatelet containing different proportions (0.25, 0.50, 0.75 wt%) reinforced epoxy/carbon fiber (carbon fiber reinforced plastic) composite laminates including interlaminar shear strength and fracture toughness were investigated. The interlaminar properties of graphene nanoplatelets/carbon fiber reinforced plastic composite laminates were improved over that of neat carbon fiber reinforced plastic composite laminates. Experimental results showed that the composite laminates containing graphene nanoplatelets possesses the appreciable improvement. The mechanisms responsible for the interlaminar enhancement were identified by studying the fracture surfaces using field emission scanning electron microscopy.

Carbon Fiber Reinforced

This paper investigates the working performance of reinforcement concrete (RC) beams strengthened by Carbon-Fiber-Reinforced Plastic (CFRP) with different anchoring under bending moment, based on the structural stressing state theory. The measured strain values of concrete and Carbon-Fiber-Reinforced Plastic (CFRP) sheet are modeled as generalized strain energy density (GSED), to characterize the RC beams’ stressing state. Then the Mann–Kendall (M–K) criterion is applied to distinguish the characteristic loads of structural stressing state from the curve, updating the definition of structural failure load. In addition, for tested specimens with middle anchorage and end anchorage, the torsion applied on the anchoring device and the deformation width of anchoring device are respectively set parameters to analyze their effects on the reinforcement performance of CFRP sheet through comparing the strain distribution pattern of CFRP. Finally, in order to further explore the strain distribution of the cross-section and analyze the stressing-state characteristics of the RC beam, the numerical shape function (NSF) method is proposed to reasonably expand the limited strain data. The research results provide a new angle of view to conduct structural analysis and a reference to the improvement of reinforcement effect of CFRP.
