滚动半固体的方法成功地被开发准备 Ni 涂的编织的碳纤维增强的 Al 矩阵合成。由于适当矩阵 flowability 和滚动压力, Al 矩阵能足够地渗透到编织纤维并且属于仔细形成一个光滑的接口的加强。4 的滚动速度 ? rad/min 提供了在热转移和材料变丑之间的微妙的平衡。盖住的矩阵应该以半固体状态被控制在碳纤维上提供更好的渗入行为和保护的效果。与纤维的增加,为超过 25% 的改进在材料的弯曲力量被获得。而且,编织的碳纤维能加强在多重方向合成,而非仅仅沿着纤维纵的方向。退火的过程支持了 Ni 涂层反应与并且扩散进矩阵,导致了弯曲力量的明显的增加。
Semisolid-rolling method was successfully developed to prepare the Ni-coated woven carbon fibers reinforced Al-matrix composite. Due to the appropriate matrix flowability and rolling pressure, the Al-matrix could infiltrate into the woven fibers sufficiently and attach to the reinforcements closely forming a smooth interface. The rolling speed of 4 rad/min offered a subtle equilibrium between the heat transfer and the material deformation. The covering matrix should be controlled at semisolid state to provide a better infiltration behavior and a protective effect on the carbon fibers. With the addition of fibers, an improvement for more than 25% was obtained in the bending strength of the materials. Furthermore, the woven carbon fibers could strengthen the composite in multiple directions, rather than only along the fiber longitudinal directions. The annealing process promoted the Ni coating to react with and to diffuse into the matrix, resulted in an obvious increase of the bending strength.
