Micro-CT technique poses significant applications in characterizing the microstructure of materials. Based on the CT three-dimensional(3D) reconstruction technology and “Avizo” 3D visualization software, the microscopic pore-throat structure of porous media can be quantitatively characterized. This paper takes the carbon fiber reinforced resin matrix composites as an example to introduce the operation process of “Avizo” in details, which mainly covers the following modules: Volume Edit, Interactive Thresholding, Fill Holes, Mask, Separate Objects and Generate Pore Network Model, then further discuss the difficult problems when the “Avizo” is employed to analyze. The microstructures of carbon fiber reinforced resin matrix composites illustrate that pores in the upper part of sample are dramatically dispersed, and mainly concentrated in the lower part of sample. The porosity of adopted cuboid is 3.6%, accordingly the numbers of pores and throats reach 268 and 7, respectively. The equivalent radius of pores seems mainly distributed in the range of 0.7–0.8μm, accounting for 28.73% of the total pore number. The surface area of pore ranges from 5 to 10μm2, accounting for 14.16% of the total pore number. The pore volume concentrates in the range of 1–20μm3, accounting for 57.46% of the total pore number. In addition, the equivalent radius of throat mainly concentrates in the range of 1–5μm, the overall length of throat is distributed in the range of 37–60μm, and the equivalent area of throat is distributed non-uniformly in the range of 5–75μm2. This work provides a basis for the further investigation of fluid migration mechanism and law in the composite materials by the numerical simulation methodology.

As a special lifting device, the lifting pole is widely used in construction of transmission line powers. Due to the special working environment, a new-type lifting pole made of carbon-fiber reinforced resin matrix composites is designed to facilitate transportation and usage. It is shown by comparison of material properties that new materials can greatly reduce structural self-weight on the condition of ensuring mechanical properties. In order to ensure the equipment is used safely and reliably, this paper carries out mechanical calculation and ANSYS finite element analysis by setting up a mechanical model, and the results show that the design is reasonable and accords with national relevant specifications.

This study investigates the transverse section property of unilateralism carbon fiber reinforced resin matrix composites in shot-beam shear conditions. Carbon fiber composites made in China and a composite T300 made in Japan were tested. Analysis was made for these composites on the shear strength data and the appearance of macro characters. Possible sequence of failure initiation and propagation of each composite was proposed by the SEM with optical microscopy observations of failed specimens. The result revealed that the interfacial property is the most important factor responsible for the failure mode of unilateralism carbon fiber composites, and the Chinese carbon fiber composites need to improve the interfacial property for wider use.

AbstractThe interfacial interaction between the fiber and matrix is the most important factor which influences the performance of the carbon fiber-epoxy composites. In this study, the graphitic surface of the carbon fibers was modified with graphene oxide nanomaterials by using a spray coating technique which is an easy, cheap, and quick method. The carbon fiber-reinforced epoxy matrix composites were prepared by hand layup technique using neat carbon fibers and 0.5, 1 and 2% by weight graphene oxide (GO) modified carbon fibers. As a result of SEM analysis, it was observed that GO particles were homogeneously coated on the surface of the carbon fibers. Furthermore, Young's modulus increased from 35.14 to 43.40 GPa, tensile strength increased from 436 to 672 MPa, and the elongation at break was maintained around 2% even in only 2% GO addition.
