“…Mesophase pitch-based carbon bers have a higher elastic modulus and thermal conductivity than the PAN-based carbon bers due to the structure in which the planar graphite molecules are highly oriented in the longitudinal direction 4) . Casting techniques, such as the melt in ltration process, have been widely used for fabricating the carbon ber-reinforced aluminum composites [5][6][7][8][9] . Some researchers [8][9][10][11][12] reported that the PAN-based carbon ber easily reacted with the aluminum melt and produced a mechanically and chemically unstable Al 4 C 3 at the ber-matrix interface during the casting process.…”

Pure aluminum and AC8A aluminum alloy matrix composites, which were reinforced with PAN-and pitch-based short carbon bers, were fabricated by squeeze casting, then the composites were exposed to a heat treatment. The effects of the ber types, composition of the matrix, and heat treatment on the mechanical properties of the composites were investigated. The bers were in a random planar arrangement in the composites. Although the aluminum carbide was formed due to the reaction between the PAN-based ber and pure aluminum during the casting process, there was no reaction products near the PAN-AC8A, pitch-pure aluminum and pitch-AC8A interfaces. Although the ultimate compressive strength of the PAN-based ber composite was greater than that of the pitch-based ber composite under every condition, the strength of the PAN-based ber composite degraded due to the heat treatment when pure aluminum was used as the matrix. Examination of fracture surface indicated that the lower reinforcing effect of the pitch-based ber would be due to delamination at the boundary between the highly-developed graphite crystallites in the ber. A hardness measurement of the bers in the composites using a nano-indenter revealed that the interfacial bonding strength between the pure aluminum and PAN-based ber degraded due to the heat treatment.

“…So, adding fibers to reinforce RMC has become one of the hot topics for researchers now. [3][4][5][6] Compared with the reinforced mechanical strength, the use of fibers also produces a certain effect to the damping performance of RMC inevitably. Therefore, related scholars all over the world have conducted a series of research on the damping mechanism of fiber-reinforced resin mineral composite (FRRMC).…”

Compared with cast iron and welded steel, fiber-reinforced resin mineral composite has better damping property that it can be used to produce precision machine tool beds in order to better satisfy the requirement of vibration alleviating. Suppose that the distribution of fibers in fiber-reinforced resin mineral composite is homogeneous, the damping model of single fiber is built on the basis of energy dissipation theory and the direction efficiency coefficient is defined as a new parameter to indicate the influence of single fiber's orientation to the damping property of fiber-reinforced resin mineral composite. Typical fiber-reinforced resin mineral composite samples with different component ratio and surface treatment of fibers are prepared and their damping ratio is measured to validate the aforementioned assumptions. Research results show that the damping performance is better with longer fiber and lower interfacial bonding strength.
