摘要: 纤维增强树脂基复合材料性能优异，广泛应用于航空航天及工业领域，而复合材料在成型过程中不可避免的产生孔隙缺陷，显著影响复合材料的力学性能。本文对纤维增强树脂基复合材料中孔隙的形成机理、测量表征方法以及孔隙对力学性能的影响进行了简要的概述。大量的试验研究表明，孔隙体积含量在0%~4%范围内时，含量每增加1%，层间剪切强度大约降低7%，层间剪切强度减少与孔隙近似呈线性关系。其它机械性能比层间剪切强度所受影响较低。
Abstract: Fiber reinforced polymers with excellent performance are widely used in the field of aerospace and industries. Voids couldn’t be avoided which affect the mechanical properties dramatically. Void forming mechanism of fiber reinforced polymers, characterization methods and effect of void on mechanical properties are reported in this paper. A large number of tests show that the interlayer strength is reduced by 7% with void content increase of 1% while void volume content is in the range of 0% - 4%. The effects of void on other mechanical properties are lower than those of the interlayer shear strength.
