The mechanical response of unidirectional composites subject to uniaxial transverse compressive loads was measured and analyzed by finite element simulation. Consistency in failure plane orientation was observed when comparing simulated matrix shear band angle to measured crack angle. A model based on hexagonal packing of fibers was proposed and the shear band angle was shown to depend on the fiber volume fraction. The effects of strong and weak fiber–matrix interfaces were considered using models with randomly distributed fibers for a valid statistical analysis. The results of these models showed that the composite compressive strength increased with the fiber loading for the strong interface case, while the strength was independent of the fiber loading for the weak interface case because of interface debonding.

“…Single fiber fragmentation test (SFFT) is a widespread method to evaluate IFSS as demonstrated by several researchers . The micromechanical interfacial properties play a significant role to provide better strength of resulting hybrid composites such as CNT‐coated CF/Epoxy (CNT‐CF/Epoxy) compared to the neat‐CF reinforced composites.…”

A floating catalyst chemical vapor deposition (CVD) unit was utilized to grow CNT onto the surface of carbon fiber (CF). The surface morphology of the resultant fibers, CNT population density and alignment pattern were found to be depended on the CNT growth temperature, growth time, and atmospheric conditions within the CVD chamber. In contrast to the neat-CF reinforced composites, improved interfacial shear strength (IFSS) between CF and matrix were obtained when the surface of CF was coated by CNT. Particularly, CF treatment condition for CNT-coating with 700 C reaction temperature and 30 min reaction time has shown a considerable increase in IFSS approximately of 45% over that of the untreated fiber from which it was processed. The proper justification of fiber-matrix adhesion featured by composite interfacial properties was explained through

“…A series of studies showed that adding carbon fiber into the concrete could improve effectively the strength and elastic modulus of the concrete [1][2][3]. The mechanical property of carbon fiber reinforced material mainly depended on the interfacial adhesion between the carbon fiber and the matrix [4,5], but the carbon fiber with smooth surface, low surface energy, resulted in the weak bonding strength between the carbon fiber and the matrix [6][7].When mixed the carbon fiber into the concrete via mechanical agitation, the fiber frequently winded with each other, which leaded to heterogeneous disperse in concrete; What's more, it was hard to exert the high strength and modulus of the carbon fibers in concrete due to the low bonding strength between the fiber and matrix resulted from the smooth surface of carbon fiber [8]. Therefore, the carbon fiber was necessary for surface treatment in practical application.…”

Four kinds of polymer emulsions were coated on the surface of coal pitch carbon fiber using atomized flow static coating method. The surface morphology of the carbon fiber after modification was analyzed by fluorescence microscope.The tensile strength of coated carbon fiber in the cement mortar and the mechanical property of the coated carbon fiber reinforced concrete were tested. The results showed that all the polymer emulsions were coated successfully on the surface of carbon fiber. The tensile strength of the coated carbon fiber in the cement mortar increased obviously, specially for the carbon fiber coated by meta chloride copolymer emulsion, whose tensile strength improved by 61%. The tensile strength of the coated carbon fiber reinforced concrete increased by 11%, the fracture energy increased by 47% and the max crack width increased by 18.5% when the content of the carbon fiber coated by meta chloride copolymer was 1.7 kg/m3.
