摘　　要：复合材料桨叶作为直升机旋翼系统的关键部件,凭借较高的比强度和比模量、优异的抗腐蚀性能、较强的可设计性以及极长的疲劳寿命等特点广泛应用于直升机领域。但是,在模压成型过程中总会存在某些因素影响桨叶成型质量,进而形成缺陷。基于此,针对3m内的模压桨叶提出常见生产缺陷的修理工艺及故障预防方法,以期有效预防和处理复合材料桨叶生产中的缺陷,使其保持或接近原有的使用性能。As a key component of helicopter rotor system,composite blade is widely used in helicopter field due to its high specific strength and specific modulus,excellent corosion resistance,strong designability and high fatigue life.However,in the process of molding,there are always some factors that affect the molding quality of the blade,and then form defects.Based on this,the repair process and fault prevention methods for common production defects of the molded blade within 3 m are proposed,in order to effectively deal with and prevent the defects in the production of the composite blade,so that it can maintain or close to the original performance.
