缝合技术作为一种复合材料液体成型预制体的有效连接增强的方法,对薄厚制件均适用,同时根据预制体的实际情况选取不同缝合方式与工艺参数,可满足实际应用中对复杂形状纤维预制体的要求。以碳纤维为增强体的先进复合材料与传统金属材料相比,具有比强度和比刚度高、可设计性强、疲劳性能好、耐腐蚀、便于制造大型整体件等优点。随着复合材料设计和制造技术的不断发展和成熟,先进复合材料在军、民用飞机上的用量也在不断
As an effective method to enhance the effective connection of liquid preform of composite material, the suture technique is applicable to the thin and thick parts, and different suture methods and process parameters are selected according to the actual situation of the preform so as to meet the requirements of prefabrication of complex shape fibers in practical applications Body requirements. Compared with the traditional metal materials, the advanced composite materials reinforced with carbon fiber have the advantages of high specific strength and specific stiffness, strong designability, good fatigue performance, corrosion resistance and easy manufacture of large integral parts. With the constant development and maturation of composite design and manufacturing technology, the amount of advanced composite materials used in military and civil aircraft is also constantly
