“…Short carbon fiber-reinforced magnesium alloy matrix (C sf /Mg) composites are one typical representative of the short fiber-reinforced composites, which have important potentials in many cutting-edge industries including automotive, aviation, aerospace, and national defense industries, etc., due to their lightweight, excellent mechanical properties, low thermal expansion coefficient, and high damping capacities.

In this article, the fiber orientation evolution in the C sf /Mg composites with a large deformation is investigated. The principal strain-induced fiber orientation evolution mechanism, which states that the fiber orientation evolution in the C sf /Mg composites with a large deformation is determined by the principal strains, is proposed. The fiber orientation distribution factors F i ði ¼ 1, 2 and 3Þ taking the form of the principal strains are proposed to quantitatively characterize the fiber orientation distribution in the C sf /Mg composites. The fiber orientation factors F s i predicted by the finite element simulation based on the principal strain-induced fiber orientation evolution mechanism are compared against those F m i measured from the micrographs of the extrusion experiments of C sf /Mg composites. The results demonstrate that the principal strain-induced fiber orientation evolution mechanism is valid and convenient to predict the fiber orientation evolution in the C sf /Mg composites with a large deformation. In the extruded C sf /Mg composites, the fibers are reoriented toward the direction of the maximum principal strain and deviated from the direction of the minimum principal strain.

“…In general, the strength of Al matrix composites or Mg matrix composites decreased monotonously with the increase in temperature [16][17][18][19][20][21][22][23]. Akbulut and Durman [16] found that the strength of short Al 2 O 3 fiber-reinforced 7075Al composites was decreased with the increase in temperature, and they concluded that the high temperature performance of short fiber-reinforced composites was mainly affected by the properties of matrix alloy at elevated temperature.…”

In this work, aluminum alloy with a high concentration of magnesium (5A06) was reinforced with 55 vol% unidirectional ultra-high modulus and highly graphitized carbon fiber (M40J) using pressure infiltration method. The effect of temperature on the bending strength of the C f /Al composites was investigated from room temperature to 500°C. The experimental results showed that the strength of M40J f /5A06Al composites was not affected by temperature from room temperature to 200°C. The bending strength of the composite at 300°C was decreased by 30% compared with that at room temperature. In order to evaluate the extent of interface weakening, the length of fiber pullout was measured. The results showed that the pullout length reached the maximum at 300 and 500°C, which indicated weak interface at the corresponding temperature. The DSC curve presented obvious heat absorption peak at around 300°C, which may be attributed to the dissolution of the interfacial product b (Al 3 Mg 2 ) phases at the C/Al interface. The bending fracture surfaces of the composites after three-point bending tests were observed by SEM, plastic-viscous flow of the matrix were observed at the samples tested at 500°C. The predominant mechanisms for high-temperature damage of M40J f /5A06Al composites are matrix softening caused by dislocation recovery and interface weakening caused by the dissolution of interfacial products.
