摘　　要：对碳纤维复合材料内孔隙的微观形态进行了观察和图像分析,并对孔隙的形态特征进行了统计分析。结果表明,在碳纤维复合材料中孔隙大多发生在层间,而且会沿层间发展,孔隙的面积和长度都会随孔隙率的增加而增加。孔隙率越大孔隙的宽长比越小,形状越细;而孔隙率越小孔隙的宽长比则越大,形状更加接近圆形,而且分布比较分散。The morphology of pores in carbon fiber reinforced plastics （CFRP） was statistically studied using microscopy and image analysis. The results show that pores tend to occur at the interfaces between the adjacent laminae and elongate along the interfaces. Both the area and the length of the pores increase if the pores content rises. It is also observed that the aspect ratios （width to length of a pore） of pores tend to be larger when the pores content decreases, and the pores are rounder and distribute more sporadically.
