The invention discloses a foam sandwich structure composite airfoil and a forming method thereof, and belongs to the technical field of composite design and forming. In order to solve the problems that in the forming process of a traditional composite airfoil, the foam unloading forming pressure is insufficient, volatile matter cannot be discharged and the like, a mold pressing co-curing forming process is mainly adopted, and a glue flowing hole with a specific structure is designed in a foam core material so as to optimize resin fluidity and gas emission. The overall quality of the composite airfoil can be effectively improved, the defects of lack of glue, bubbles, layering and the like are avoided, and uniform distribution of resin in the curing process is ensured, so that the compactness, uniformity and structural stability of the composite are improved, and the resistance performance and durability of a product are enhanced.

    本发明公开了一种泡沫夹心结构复合材料翼面及其成型方法,属于复合材料设计成型技术领域。本发明为解决传统复合材料翼面在成型过程中出现的泡沫卸载成型压力不足、挥发份无法排出等缺陷问题,主要采用模压共固化成型工艺,并在泡沫芯材中设计具有特定结构的流胶孔以优化树脂流动性和气体排放。本发明能够有效提高复合材料翼面的整体质量,避免缺胶、气泡和分层等缺陷,确保树脂在固化过程中的均匀分布,从而提高复合材料的致密性、均匀性及结构稳定性,增强产品的抗力性能和耐用性。
