摘　　要：采用超声波振动法制备了油气田领域中应用较为广泛的炭纤维铝基复合材料,研究了层间角度对层状炭纤维铝基复合材料显微形貌和拉伸性能的影响,并对断口形貌进行了观察。结果表明,当层间角度在0°~90°时,方向A的炭纤维/铝基复合材料的抗拉强度都高于铝合金基体,而方向B的炭纤维/铝基复合材料只有在层间角度90°时的抗拉强度高于铝合金基体,其余方向的抗拉强度都低于铝合金基体;在层间角度为0°时,方向A和方向B的复合材料的抗拉强度差值最大,约为140.2 MPa;随着层间角度的增加,方向A和方向B的复合材料的抗拉强度差值逐渐减小;层间角度为90°时,炭纤维/铝基复合材料的拉伸性能均匀性最好,为适宜的制备炭纤维/铝基复合材料的层间角度。Carbon fibre reinforced aluminum matrix composites,which are widely used in oil and gas fields,are prepared by ultrasonic vibration method.The effect of interlaminar angle on the morphology and tensile properties of layered carbon fibre aluminum matrix composites is studied,and the fracture morphology is observed.The results show that the tensile strength of carbon fiber/aluminium matrix composites in direction A is higher than that of aluminium alloy matrix when the interlaminar angle is between 0°and 90°,while that of carbon fiber/aluminium matrix composites in direction B is higher than that of aluminium alloy matrix only when the interlaminar angle is 90°and that of other directions is lower than that of aluminium alloy matrix.When the interlaminar angle is 0°,the tensile strength of composites in both direction A and direction B are higher than that of aluminium alloy matrix.The maximum difference of tensile strength is about 140.2 MPa.With the increase of interlaminar angle,the difference of tensile strength between direction A and direction B gradually decreases.When the interlaminar angle is 90°,the uniformity of tensile properties of carbon fiber/aluminum matrix composites is the best,which is the best choice of interlaminar angle for the preparation of carbon fiber/aluminum matrix composites.
