摘　　要：以14 K展宽碳纤维为原料,采用单层碳纤维平行排布、10 mm间隔的双层碳纤维垂直分布的空间模式,利用高透明水晶滴胶A、B胶复合双层碳纤维丝束并固化成型,制备了弹性滴胶/展宽碳纤维压力分布监测的传感型复合材料。利用FT-IR、接触角和偏光显微镜对该复合材料组分、结构和形貌进行表征,并测试该复合材料的压弹性能,研究了其压力分布的监测效果。结果表明:滴胶基体具有优异的回弹性能,通过铺层碳纤维形成的若干电容阵列,每个垂直碳纤维束交点形成的电容具有线性的压力-电容变化关系,电容阵列的组合形成了可以测试压力分布的灵敏传感复合材料,在应用于脚底压力分布的监测方面具有重要的应用前景。Using 14 K spreading carbon fibre bundle as raw material,using single layer carbon fibre parallel arrangement and 10 mm spaced double layer carbon fiber vertical distribution spatial pattern,using high transparent crystal A,B glue composite double layer carbon fiber tow and solidifying,the sensor composite material for monitoring pressure distribution of elastic glue/broadening carbon fiber is prepared. The composition,structure and morphology of the composite are characterized by FT-IR,contact angle and polarizing microscope. The ballistic performance of the composite is tested and the monitoring effect of the pressure distribution is studied. The results show that the adhesive matrix has excellent springback properties,through a number of capacitance arrays formed by the layer carbon fiber,the capacitance of each vertical carbon fiber bundle intersection has a linear pressure capacitance change relationship,and the combination of capacitance array forms a sensitive sensing composite that can test the pressure distribution. It has an important application prospect in monitoring the pressure distribution of sole.
