摘要: 通过改变固化工艺制备了含孔隙的碳纤维复合材料试样,采用超声检测对试样进行了初步的孔隙检测与筛选,采用金相显微法对典型区域的孔隙率、孔隙分布和形貌特征进行统计。实验结果表明,固化压力不足和袋内真空不合适会引起复合材料内部孔隙的产生,且孔隙的分布存在必然性和随机性,孔隙形貌与孔隙率存在一定的联系。

关键词: 复合材料, 孔隙率, 形貌特征, 超声检测

Abstract: Composite specimen was prepared by changing forming parameters. Ultrasonic testing was used for preliminary detection and screening. Porosity of specimen, voids distribution and morphology characteristic of typical area were counted and analyzed by metallography microscope. Experimental results show that the composite internal voids are caused by insufficient pressure and inappropriate bag vacuum. Pore distribution is inevitable and random, and pore morphology is related to porosity.

Key words: composite, porosity, morphology characteristic, ultrasonic testing
