一、前言以前，提高复合材料层间剪切性能的途径主要是通过改进基体与增强材料的界面性能，这种方法成本高，工艺复杂且作用也不太明显。到了８０年代，国外出现了复合材料三维整体编织技术，它主要是通过改变增强材料的编织方法由二维编织物改为三维整体编织物。用三维整体编 First, before the introduction, to improve the interlaminar shear properties of composite materials is mainly through improving the substrate and the reinforcing material interface properties, this method is costly, the process is complex and the role is not obvious. In the 1980s, three-dimensional integral weaving technology for composite materials emerged abroad. It mainly changed the two-dimensional weaving fabrics into three-dimensional integrated weaving fabrics by changing the weaving method of reinforcing materials. Three-dimensional overall editing
