摘要:

试验研究了用于航空结构的三维整体编织复合材料单耳承力接头在静载条件下的承载能力与破坏模式。单耳接头试样采用RTM(Resin Transfer Molding 树脂传递模塑)工艺制成,重点研究了由3种编织工艺(三维四向、三维五向和三维六向)、2种连接孔加工方式(机械钻孔和编织孔)、2种几何外形所组成的10组三维编织复合材料单耳承力接头的破坏机理与破坏载荷。对其在航空结构中的可应用性做出了评估。

Abstract:

Load response and failure modes of 3d braided composite lugs were studied experimentally. The objective of the study was to get information on the stiffness, strength and failure mode of the lug, as well as on the applicability of the analysis method used to predict lug load response and failure. The test lugs were manufactured with the Resin Transfer Molding (RTM) technique. The test specimens were loaded parallel to the lug centerline.
