摘　　要：预制体缝合结合液体成型工艺可以有效地改善复合材料制件的层间性能,对复合材料预制体OSS缝合的工装进行了研究。采用不同针距、行距缝合了预制体,采用RFI工艺固化了制件,并测试固化后制件的弯曲强度和层间剪切强度,对比了不同缝合参数对制件弯曲强度和层间剪切强度的影响。Preform stitching combined with liquid forming process can effectively improve the interlaminar properties of composite parts.This paper studies the tooling of OSS suture of composite preform.The preform was sewn with different needle spacing and row spacing,and the parts were solidified by RFI process.The bending strength and interlaminar shear strength of the cured parts were tested,and the effects of different stitching parameters on the bending strength and interlaminar shear strength were compared.
